Prof. Ishikawa through the Eyes of His
Siblings, Family, and Relatives

6.1 Talking about Elder Brother Kaoru

Prof. Kaoru Ishikawa, My Elder Brother, and I
Kiyoshi Ishikawa
My elder brother Kaoru and I were close in age. We also went to the same highschool under the old system and graduated one year apart from the same department of
the same university. Because of these, people often mistook me for my elder brothersince we were students.
I was upset when a department professor started talking to me about graduation
thesis, standing next to my stool in a bathroom. He mistook me of the sophomore for
Kaoru of the junior. His students would greet me at Tokyo Station after the war andsome executives of a large enterprise would address me Professor Ishikawa on the train
or elsewhere. I have experienced these mistakes countless time. We lived close to eachother, but it was fortunate our wives did not make the same mistake.
I am getting old recently, so I am afraid of the same thing might happen on me.
Three or four years ago when Kaoru got the latest sick, he recovered for a shortperiod. I gave him a serious advice, but he did not listen to me. On the contrary, hebecame stubborn and did not take care of himself. He suddenly passed away after two
years. He lived ten years shorter than our father, and 6 to 7 years shorter than ourmother.
I suffered from intracerebral hemorrhage, the same disease with Kaoru even I tookcare of myself. Fortunately it was not serious and now I get rehabilitation training. I
hope I will live longer than Kaoru and stay healthy till my parents’ age. However I don’tknow what will turn out from now on because Kaoru and I are quite alike.
Kaoru was so stubborn about his health that he didn’t listen to his family andyounger brothers. He used to tell CEOs of some large enterprises that they had toPART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

manage the company avoiding being confused in any case like CEO’s absence for amonth or two or becomes ill. However he insisted that, when he himself fell ill, heshould attend the school’s commencement and enrollment ceremony. Those were held
just two weeks before he passed away. He attended those and collapsed afterward.
I may be biased for him because I am his brother. He learned statistical quality
control in late 1940s, developed a sampling method of iron ores, contributed to therationalization of the steel industry, initiated the QC Circle Movement and establishedthe concept of TQC for all the industries. As a result, the Japanese economy had been
extremely strengthened. In a way, I believe that Kaoru was one of Japanese wirepullers
behind the today’s Japan-US economic frictions.
I hope I will live as many years as possible not like Kaoru. Now my age is one year
older than that of Kaoru’s death. How many years longer can I live from now?
(Second brother; Chairman of Mitsubishi Oil Co.)

Memories of Brother Kaoru
Makoto Ishikawa
Brother Kaoru, you have passed away too early. Everyone goes to the heaven
sooner or later, I expected you could live at least ten years more, so I am very sorry
indeed. Since you passed away, the Ishikawa family has lost its core. Of course, his
sister-in-law Keiko does her role instead of Kaoru, however I realize that we reallyrelied on Kaoru. Please observe us from the heaven.
Other people will write about him after he got into society. I will write about a few
memories of him when I was a small child.
When I was a child, I was cheeky a little bit. I was selfish because I am theyoungest one of four brothers. I would often take it out on Brother Kiyoshi. He wasalways patient and did not pay me much attention. However, finally his patience run out
and he beat me. I resisted him with all my strength, but there is no help for it. At thetime Brother Kaoru came and relieved me. I really felt relieved even I said nasty thing
to Brother Kiyoshi.
In the first summer at his junior high school days, Kaoru’s white school uniform
pants looked like he was so smart for me. I remember how proud he was of himself.
There were iron bars in the athletic field behind our house in Takinogawa. There weresand underneath the iron bar. Kaoru was practicing there for his school curriculum andhe fell down from the bar. His lower jaw was cut with his teeth, and he had several
114

Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

stitches. The scar had been remained for many years. Mom was quite worried about that.
These iron bars were taken away soon after Kaoru got injured. Maybe because of this,Brother Kiyoshi and I were not good at iron bar.
Brother Kaoru was quite a hard worker and he had studied all the time. I think his
success resulted from his constant efforts.
Here is one memory of him after I became an adult.
During the war, I think it was June or July of 1942. I was going to be transferredfrom the Fourth Naval Fuel Factory in Kyushu to the Naval Fuel Factory in Borneo inthe south. I got on a naval ship in Kure after I once went home. Mom suggested that weall three brothers also should see him off together. At that moment Brother Kaoru who
was already in the reserve unit however, he went there from Wakamatsu in Kyushu with
Sister in law Keiko. They had just been married in this year’s spring. Brother Kiyoshi
went there from the Naval Fuel Factory in Tokuyama. Both of them put on their whitesummer uniform. Mom and I went there from Tokyo. We were all together at Suikoshain Tokuyama. Late at night, we decided to take a picture of all of us. We visited several
photo studios in town. Finally one of them was willing to open and took photos. Mom
looked very happy surrounded by all three sons putting on white uniform. I think Sisterin law Keiko also put on a white dress. It was my farewell photo, though.

Thinking of Brother Kaoru Ishikawa
Rokuro Ishikawa
My brother literary grew up with expectations and faith of parents, siblings andsurrounding people on his own shoulders, as the first and legitimate son of 8 brothers
and one sister (8 men, 1 woman) in the Ishikawa family.
When a notice, in which my brother passed the exam for the Department ofApplied Chemistry, at the University of Tokyo, came in, from Uncle Nobuo Seki who
was a professor in the Department of Engineering at that time, I clearly remembered myparents happened to be at home, and were delighted with tears. As this kind of scene
never happened with other brothers and sister, I could tell how much my parents
expected of him.
Because there were a lot of boys, my parents tried to keep order in the family bybringing up my brother idealistically, as good examples for other brothers and sister. My
brother steadily grew up following expectations, completed study with outstanding
academic results, became a member of society, welcomed a beautiful, warm and cleverwife (widow, Keiko) to our family in a nearly all-male environment, and built a happy
family.
After graduating from the University of Tokyo, he joined the Nissan Liquid FuelCompany, which introduced technology from Germany “to manufacture artificial
petroleum by liquefying coal,” in alignment with a national policy, at that time, in orderto succeed our father’s business. Then, upon retiring from a short-term engineering
service officer, in the Navy, he became an associate professor at the University of Tokyo,
in response to their request.
Although he played an active role, as an authority on QC, in bridging academy andindustry, I imagine that my brother would have been highly successful even as
management, considering his personality and capability, if he had chosen to stay in theindustry.
My brother was beloved by everyone, with respect, because he treated surrounding
people calmly, evenly and reasonably out of goodwill, as a family head. He was also
extremely precise and diligent in nature. In his school days, he used the Rolleiflex ofGermany, which was rare in those days, and engaged himself in film development,
printing, enlargement, trimming and producing an elaborate photo album, whenever hefound himself free. His sorting and putting personal belongings in order, was an objectof magnificence to our eyes.
When I became the President at Kajima Corporation in 1978, I introduced TQC, in
116Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

order to eliminate the negative effects created throughout its 140 year-history, torejuvenate the company and to create a culture of openness, which resulted in a huge
success through my brother’s strong guidance and assistance. Now I recall, withappreciation to my brother, that we were able to achieve constitutional improvement,
drastic improvement of business results, and were awarded the Deming Prize 5 years
after introduction of TQC.

Chairman, Kajima Corporation)

Memories of My Brother-in-Law
Mrs. Kiyoko Ishikawa
I joined the Ishikawa family as the wife of their seventh brother Shichiro and mybrother-in-law Kaoru was always great to me. Shichiro, my husband, would tell me
about Kaoru worked vigorously as a grand senior member of JUSE (Union of Japanese
Scientists and Engineers). I also was always impressed with his wife Keiko for thefaithful and submissive manner she served him with. Her attitude which she gave thefirst priority to serve him was a role model for me.
We spent our holidays together at Karuizawa when our children were small. In one
summer, some professors of JUSE also stayed overnight. In the daytime, they studied
their quality control and played golf. In the evening, they had drinks and sang various
songs one after another. Those who forgot tunes were called tone-deaf, and those who
forgot words were labeled as word-deaf. I remember well the pleasant time we had
together.
My contacts with Kaoru were usually through my husband Shichiro as a cushion,
but in 1980 Shichiro developed an incurable illness. Since then I had to rely on Kaoru.
Shichiro’s parents had already passed away and Kaoru as the family head had to makeup his mind whether tell me about Shichiro’s cancer or not. He had talked about it withhis brothers and relatives beforehand. He decided to tell me about the illness of myhusband because I am tough. Then he came to Hotel Ohtani and told me that even hisbusy schedule. To meet his expectation, I determined to fight this situation. The doctor
told us he would live only for six months. He received the latest treatments, thanks to
Kaoru. He was in and out of the hospital for three years since then, and he was able to
be at the wedding of our eldest daughter and at the birth of our first grandchild. He had
no pains and died in 1983. We never told him about the cancer. I was always consoled
117

PART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

when his brothers visited him and encouraged him without telling anything about theillness. Kaoru with the deepest brotherly affection observed the illness calmly as ascientist and gave proper advice. I am deeply grateful to reliable Kaoru being there in
those difficult moments. But he passed away so suddenly and I have no words to utter.
Perhaps Kaoru and Shichiro are talking about QC in heaven.
(Wife of the late seventh brother, Shichiro Ishikawa,
Managing Director of Honshu Paper Co.)

Thinking of My Big Brother-in-Law
Shinichiro Shimojo
I met elder brother in law Kaoru for the first time in the fall of 1948. My
wife-to-be and I were together in an interview arranged by the late Hisatada Hirose who
was the second Minister of Health and Welfare. Kaoru, who is the eldest son of
Ishikawa family was there to introduce me his sister Yasuyo, my wife-to-be. He musthave approved me in the match-making interview. That was the beginning of myassociation with Prof. Kaoru. He was an academic and solid figure since his youth, but
he was also very considerate to his sister. We became relatives after I married to her, andwe would drink together and play golf. Those memories pass my eyes with nostalgia. I
think he had in himself the fruit of the stern home education by his father Ichiro
Ishikawa, the first chairman of Keidanren, and his mother Tomiko. Even though hegrew up in a famous business family, he was always plain and modest. People were
impressed with his attitude and they respected him.
After graduating from the university, he served in the Navy as a duty engineering
officer. He still had some of his Navy habits even long after the war. For instance, hewould call anyone “Kisama†” (you) in front of others, and I was often annoyed with it.
He loved to drink, and he was a heavy drinker. When he had more drinks, he would
become more talkative and argumentative. He would also utter more “Kisamas.” His
speech was often not clear even when he was sober, and we did not understand him
when his words were slurred as he got drunk, but he would still keep arguing.
His great contributions were his devotion to the study and promotion of QC as hislife work. Japanese industries have become very competitive globally and largely thanks†

Kisama is a formal expression used by the officers of the Imperial Japanese Navy addressing eachother. Outside the Navy, it was considered a very rough but friendly expression, therefore we seldom
used it.
118

Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

to his management guidance of quality control, and his works were highly appreciatednot only in Japan but also in the western countries. We miss him very much.
He was a serious scholar and ran around all over for QC promotion. He studied late
into the night. He was also a heavy smoker. Thus he did not take good care of himself.
Shortly before he passed away, I played golf with him at Karuizawa. His score was notgood then and I think his health steadily deteriorated afterwards. He was a dearbrother-in-law for me, and he was an important scholar for the country. Prof. Kaoru
Ishikawa passed away too early. I wish to pay my sincere respects for him.
(Husband of his sister Yasuyo; a member of House of Councilors;
former Minister of Health and Welfare)

About Prof. Kaoru, My Elder BrotherHachiro Ishikawa
My eldest brother Kaoru was 15 years older than I. He was also my senior at the
Applied Chemistry Dept. of the same university. Not only that, he was my teacher in theclass of Design of Experiments. When I was in the kindergarten, he was in theuniversity. I put on his school cap and pretended to be Fukuchan who was a character inthe comic on The Asahi Shimbun (newspaper). When his wife Keiko asked me to write
something in his memory, I accepted it right away as he had been such a dignified figureof almost 60 years for me.
Prof. Kaoru majored in Applied Chemistry. Even he was not particularly good atmathematics, he went from Design of Experiments to statistics, and then to quality
control. Behind these, there is the fact that he had been involved in the work to produce
fuel oil by liquidating coal in Northern Kyushu during the war.
In his experiments of processing coal, he was bothered with the quality dispersionof coal. He must have felt keenly that a statistical approach was required to analyze theresult of his experiments. Thus he studied it hard and became an expert of quality
control.
After I joined the company, I was disappointed when I used the Design ofExperiments I had learned from Prof. Kaoru. If you plot experimental data on a graph,
you could tell its correlation instantly. I easily thought you would get the same result if
you take time by calculating in the Design of Experiments. But I gradually understoodthe significance of showing objective results of experiments in figures.
As he analyzed statistically the dispersion of quality of raw materials and the119PART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

experimental results, he must have stepped into the quality control which ensured
products of stable quality and predictable experiment results with the use of
stable-quality materials.
After the war, we decided to live close to our parents and Kaoru’s family in
Chofu-city; west of Tokyo. All our brothers gathered together, drank, argued, andlectured. The parents and brothers also played mahjong. On Sundays, we all worked on
the field. I still remember clearly the odd-looking Brother Kaoru who was spreadingchicken droppings in the field.
Whenever I visited him in the evening, he was always in kotatsu† and wrote
something, a report or a lecture. A glass of whisky with ice and a large ashtray full ofcigarettes butts were always by his side. We used to call each other stubborn, but Kaoru
was after all the most stubborn as he never stopped smoking despite the serious warningfrom his wife. If he had listened to her, he would have lived ten more years and give me
more guidance.

6.2 Relatives talk about Kaoru

Kaoru’s Kisama††
Eiichi Ujiie
Kaoru was famous for addressing his colleagues, schoolmates, students, andyounger brothers alike as “Kisama (impolite way of addressing someone).” One day, I
heard his mother, Tomiko, whispered to me “I hope he is not being bossy,” when she
heard him say Kisama. Well, it’s not at all mean that he was arrogant. It was his way ofaddressing others with a sense of intimacy like there is a Japanese song “Doki No
Sakura (literally, cherry blossoms of the same season).” It’s a popular song of theJapanese Imperial Navy, whose lyrics include the phrase, Kisama To Ore (you and I).
We should say that it was based on the tradition of the Navy that he treasured, as heserved as a 2nd short-term engineering officer of the Japanese Navy, as a naval†††

Kisama (“貴様” in Japanese Kanji, the pronoun “kisama”) means “you” in English. Kisama is aformal expression used by officers of the Imperial Japanese Navy addressing each other. Outside theNavy it was considered a very rough but friendly expression, therefore seldom used. Prof. Ishikawa
favored the use of this word among friends even outside the Navy.

ordnance lieutenant.
Kaoru boarded the Maya, a state-of-the-art heavy cruiser of the time, as a trainee in
1939. I also boarded the Maya in 1940 as a Paymaster Sub-Lieutenant, 1st Class, inservice for two years. I was a Paymaster Lieutenant-Commander when the war ended,
but I still have fond memories of the Maya on which I served as a 1st class officer. My
sister, Keiko, married Kaoru on February 11, 1942 and I became a relative of the
Ishikawa family. In 1944, my younger brother Takuya was ordered to board the Maya asa Paymaster Sub-Lieutenant, 1st Class, in service for two years.
I think it was an extremely rare occurrence in the Imperial Navy that three brothers,
although in different periods, boarded the Maya as a lieutenant solely by chance. I am
intrigued by the inexplicable connections between us. Under the Treaty for the
Limitation and Reduction of Naval Armament, known as the London Naval Treaty of1930, Maya was the last cruiser built. While it was being built, many additional requests
and changes in design were made by the Naval General Staff and Imperial Japanese
Navy Engineering Department. So, the inside of the cruiser was narrow andcomplicated.
As Kaoru was a neat and meticulous person, wearing a navy cap for on board use
and the brownish-red work uniform of an engineer officer, he must have carefully
checked from the main gun command post on the bridge to the engine room located in
the ship's hull to complete the detailed journal of each day. And while in the gun room,
he must have had heated discussions with lively young officers, addressing each otheron a kisama basis.
As I reflect on the days gone by, I warmly and strongly remember his great
personality.

To commemorate the 3rd anniversary of the death of Prof. Kaoru Ishikawa, theyplanned to publish his memoir and I was requested to contribute with my memories ofProf. Ishikawa. Right up to the end, Prof. Ishikawa performed his duties as the Presidentof Musashi Institute of Technology, sustained his enthusiasm for companywide
Japanese-style quality control and TQC activities and left a major mark in the world. I
121PART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

am sure that his great achievements will be described by people in various industrial
communities from their respective viewpoints.
I hardly had any dealings with him in the public place where he was very active
until when his second son, Akira, and my second daughter Kazuko married in 1979.
After that I had had family-like relations with him for about 10 years.
We were the generation that entered an old-style-education-system high school,
and then the University of Tokyo, joined the military, and then became a member of thesociety almost simultaneously. Therefore, as soon as we had a drink together, we felt
like we had been friends for years. Sometimes while chatting and drinking, we
discovered that we had a mutual acquaintance, and episodes with him made us singsongs and drink many more cups of Sake. I think it was the year following the marriageof our children, when my wife and I invited Prof. and Mrs. Ishikawa, and Mr. and Mrs.
Hibino, who are the parents-in-law of my first daughter, to hold a cherry-viewing party
in our house, as we could enjoy the cherry blossoms in the grounds of Todoroki
Fudoson temple as viewed from our house. When we got very drunk, Prof. Ishikawa
suddenly stood up, leaned against the rail of the veranda, caught a few falling cherry
blossom petals with his Sake cup and calmly drank them up. I can still see his graceful
posture on that occasion.
On another occasion when the newlyweds’ new house was completed in thepremises of his house, we had a celebratory drink, sitting with our grandchildren under
the wisteria trellis in his beautiful garden. I can still remember as if it were yesterday.
I think it was around that time that I had an opportunity to meet Prof. Ishikawa for
the first time in his public capacity. This was a memorable experience in many ways
which I would like to share. I was in the middle of a major turning point in my life; it
was soon after I had retired from the position of the President of Tokyo Hoso Kogyo
Corporation, a subsidiary of Mitsubishi Mining, where I had worked for many years andbecame the Senior Advisor to the company. As I was now related to Prof. Ishikawa, I
wanted the executives of our company to listen to his lecture. As Prof. Ishikawa kindly
accepted my request, I informed our company staff to gather as many employees as
possible as it was an unrepeatable opportunity.
When I reached to the venue on the day, I saw many young employees there, but
no executives. This made me annoyed. Prof. Ishikawa, however, discussed fromJapanese style management to the essence of TQC activities in detail, which deeply
impressed the entire audience.
Well, after the session, when there were just the three of us, that is, Prof. Ishikawa,the General Affairs Manager who served as the MC, and myself, he murmured, “All the122Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

managers of your company look young.” The General Affairs Manager had a hard timecoming up with what to say and finally explained that the company had offices indifferent locations and it was difficult for busy executives and mid-career workers toparticipate in the event, and all new employees had been assembled. Of course, theDoctor was well aware of that and had made his remarks in jest. I was so ashamed that I
wanted to crawl under the rug. Our staff, including myself, deeply regretted forgenerally having had little interest in these activities. As the proverb goes, the sting of a
reproach is the truth of it. His lecture, however, encouraged young employees to get
enthusiastically involved in the activities. I hear that now a QC Group has been
established in the company and even the President is deeply committed to the activities,
which again impressed me a lot. Although this is a minor episode, I wanted to mention
it here as evidence of his positive influence.

6.3 Thinking of Father“Have Three Children and Send One Abroad”
Tadashi Ishikawa
It was midnight when my flight arrived in Sao Paulo one day behind schedule due
to engine failure. When I finally checked into the hotel, a phone call was waiting for me.
It was my wife calling from Chicago to tell me that my father had collapsed.
It was 2 years ago, and half a year from my relocation from Komatsu Ltd., Japan to
Komatsu Dresser Company in the U.S. and shortly after my wife and 5 children joined
me in Chicago. Before leaving Japan, I asked my father’s doctor if he would be OK and
to please take good care of him, because he was not in the best of health at that time.
But still, I was simply shocked to hear the news.
When I arrived back in Japan, he was unconscious and could not speak to me. It
seemed to me, however, that he had left this life, saying, “Good things and bad things
happen to everyone,” which was one of his pet phrases.
My father always came home late from work and seldom had a chance to havedinner with his family. While at home, it was usual for him to keep working in the roomwith a kotatsu heater until over midnight. He was a work-oriented, hard worker, stern inmany ways. On the other hand, he was a good-natured person, cherishing his friends as123

PART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

well as his wife, children and grandchildren, and often moved to tears while watchingTV.
“Embrace good and evil alike,” “Constant pitch,” “Have three children and send
one abroad,” and “Good things and bad things happen to everyone” were among his
frequent sayings. When I fondly remember these phrases, I think we children should
hand them down to his grandchildren.
Last but not least, I would like to thank all, including the editorial committee
members and contributors of stories and other materials, who kindly took time out of
their busy schedule to make the publication of his memoir possible.

currently Vice President of Komatsu Dresser Company, U.S.A.)

I Wanted to Thank You More
Mrs. Noriko Ishikawa
When I heard the news that my father-in-law had broken down, it was only 3
weeks after I had moved to the U.S., with my 5 children to live with my husband, who
had been transferred there for work.
I felt as if I heard my father-in-law’s voice saying that he was glad I had departed
safely, and that I should be diligent.
My husband and I were at a major turning point a few times in our lives. On eachoccasion, my father-in-law gave us appropriate advice, supported and encouraged us. At
the side of my father-in-law, who sat at the kotatsu having the same look on his face,with documents in front of him, my mother-in-law smiled and spoke for him. He only
nodded for our words of appreciation, and she gazed at him with a smile on her face. A
scene like that still floats vividly in my memory.
His tenderness and care were always nonchalant and wrapped broadly around us.
Because of his support, I was always able to go on a new path with the sense of security,
I believe.
I wish I could have said thanks to him more. That’s my only regret.
(Wife to the first son Tadashi)

Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

Thank You, Father
Yasushi Kurokawa
My emotional exchanges with my father-in-law, Prof. Kaoru Ishikawa, began inAugust 1968, before I married Hiroko, his eldest daughter, or at least that is my
self-serving understanding. In April 1968, Prof. Ishikawa had Hiroko and I make apromise. He told us if we kept that promise for four months, he would give us
permission to marry and August was the month when the promise was to be fulfilled.
On the day in August, I told him on the phone that we had kept our promise and hetold me to come to his house. I was shown into the living room and nervously waitedfor him. As soon as he hurried into the room, he extended his right hand to shake handswith me, saying, “Good job.” As I heartily shook hands with him, in my mind, theterrifying father-in-law transformed into a sensible old man, and I felt a subtle
emotional exchange between us.
Since then, the channel of exchange continuously broadened year after year for
about 20 years until his death. In all those 20 years, I learned a lot from him.
“Good things and bad things happen to everyone,” “You are only a half-fledged
businessman if you can make the best of your subordinate, but a full-fledged
businessman if you can make the best of your superior,” “Turn a listening ear to others,”“Communication over a cup of Sake”—these are some of his frequent sayings, which I
heard from him at the table and over a drink (Actually, I learned to drink from him.). On
days off when I was feeling rather down or when I started getting lazy, I used to drop
into his house, and quite often found him writing some draft in the living room with the
TV on. Laying down his pen, he talked with me for a while, and each time I was
encouraged by his words and often felt like the scales had fallen from my eyes.
There is not enough space to write all of these memories, but I would like to tellyou.
It was when my father-in-law came to my company to teach quality control. As he
was a leading figure in the field of quality control, my expectation was high for aninteresting and informative lecture, and on the other hand, I was worried if we could
live up to his expectations. So, I was all ears on the first day with other participants inthe lecture. But the session from start to end was disarmingly easy to understand.
In the evening of that day, I said to him a little disapprovingly, “It was rather
elementary.” He said, “Speaking of quality control often involves difficult mathematicalformulas and some people think that a good teacher is one who teaches hard tounderstand concepts. But it will not help anyone. What is important is to make everyone
125PART II Human Beings are Human Beings: Kaoru Ishikawa as a Common Man

understand, so as to make their company better. Some teachers easily get mad and act
bossy, which also will never work. The point is how to communicate your idea…”
Now I have 1,400 people in my division and am often keenly aware of the
difficulty of communication. On such occasions, I remember what he said at that time:“What matters is not whether you said it or not, but rather, whether you successfullycommunicated it or not.”Early on the morning of April 13, 1989, he suddenly collapsed. In the hospital, he
was losing consciousness quickly. Kneeling down by his bedside, I said in a loud voice,“Thank you,” to him with my mind filled with thousands of thoughts from the day when
he permitted me to marry his daughter, to all the things he taught me. I am sure he heardme.

Memories of Father
Mrs. Hiroko Kurokawa
The first thing that comes to mind when I think of my late father is the image of
him sitting at the kotatsu heater, writing some draft. And my mother was always sitting
beside him. It is almost three years since he died. I would like to describe my father as I
see him in my mind.
Systematic person
He did everything systematically. If you are to buy a car, you should get a quality
car and keep it at least 10 years. This was his motto. The first family car was a
Volkswagen, which we drove for 17 years. Next came a Cedric that lasted 10 years. We
visited quite a lot of places. During each of these travels, he kept a record of everythingin his pocketbook, such as what time we left, how many hours it took from a certain
place to another, how many liters of gasoline we purchased, and how long our break
was. He wrote down everything throughout our travels. There are many suchpocketbooks of my father, serving as a reminder of our travel history.
Family Mahjong player
My father was so busy that he seldom dined with us. On rare occasions when hecame home early, his mother almost always called him, saying “Kaoru dear, are you
there?” She was inviting him to a game of Mahjong. He always accepted the invitation,
126

Chapter 6 Prof. Ishikawa through the Eyes of His Siblings, Family, and Relatives

tired he was. I think it was his way of being a good son, but my mother and we children
felt indignant at this game. It was a family mahjong played by my grandparents, myuncle and my father in a room we could not get near to.
Stubborn but gentle father
My father was in a sense very stubborn. There were times when everyone else in
the family was sure about what he had said, but if he said, “I did not say it,” theneverything got cancelled. Once on a winter’s day during our family travel, he was sittingby the window, half naked with no shirt on, and getting goose flesh. Someone said,“Why don’t you close the window? It’s cold in here,” and he stubbornly said, “No, I
don’t think so.”But that stubborn father who at first said no to my marriage, probably out ofconcern, eventually gave willing permission that even seemed all too easy.
As his work can be applied to, from time to time during the past three years, I
heard my father’s name mentioned while I was getting acquainted with someone, whichmakes me aware of the fact that my father was a great man, which I never knew while
he was alive and active.

My DadAkira Ishikawa
When I recall my father, I wonder what the source of his dynamism was. In thechaos after the War, QC started with a desire to reconstruct the country. Having people
from JUSE at the center, my father compiled QC into one structure and made every
effort to promote it, not only in Japan, but also to countries in the world. Though he hada sharp tongue, he always valued people’s hearts. Also, he was never short of defiant
spirit, and he looked so full of life and brightened up, when it came to a talk about QC.

Even when coming home late at night, he always took a bath which he loved,
firmly sat at the kotatsu in the living room, only wearing underwear, and worked until 1
or 2 o’clock while smoking, and having a glass of drink. Thanks to that, there wasalways a pile of documents in the living room, and it troubled my mother. When hewrote, he methodically brought all documents from the past and checked to make surethere was no error. He left the TV turned on, even when working, and it appeared he
was focused on his work and wasn’t watching it, but he also had an aspect ofmulti-tasking ability, and was listening to it. I believe his passion for his work was
supported by his desire that “make society (individuals, companies, countries and theworld) happy and better through QC.”
It was my pleasure and also learning opportunity to hear about my father’s
experience while sitting together at the kotatsu, in the living room with him, facing eachother. Needless to say, the lectures were very helpful, even after I started working. There
were also many occasions when I sought his advice on work and my worries. He wasnever carried away by his feelings, but always gave me a pin-point opinion, after
confirming the data.
After his death, I left Daiwa Seiko, the company I had worked at for 19 years, put
an end to my life as a corporate employee, and I am moving to a new business. I wonder
how he sees me now. Through much advice he left, in my mind, his experience and wayof thinking continue to live forever.

Father’s Looks and Glances
Mrs. Kazuko Ishikawa
Around the time when we got married, the three children and their family members
often gathered in my parents-in-laws’ house on weekends to have dinner together. We
talked a lot in a close family atmosphere and Father, smoking and with a glass ofwhisky in his hand, always kept calm, nodding along to what we said and watchinghappily over his grandchildren. In Karuizawa, in summer, during the Bon holidays, we
had a merry, happy and busy time under one roof. With a total of 10 grandchildren, it
must have been rather noisy for him, as he was usually working at his desk. But henever complained about the noise we were making, and kept doing his work. So, I think
his grandchildren were lucky to have such a grandfather, living freely and easily andenjoying the happy life of a large family. Moreover, I do not think he ever scolded or
reprimanded us. I think that was an example of his thoughtfulness toward us. We were128

greatly encouraged by the way he affectionately looked and glanced at us.
His stay in hospital started with his words: “Doctor says I have a polyp in thebowel and I think I will have it removed.” His recovery was delayed and he was foreverin and out of hospital. It was soon after the family of my husband’s elder brother moved
to the U.S. The family members remaining in Japan were busy supporting Mother, as
she was exhausted due to the daily visit to St. Luke’s International Hospital throughout
the daytime hours while Father was in hospital. On that morning, he was back home.
There was an urgent phone call from Mother, and we rushed to the main house. My
husband gave artificial respiration as best he could and kept encouraging his
unconscious father in the ambulance and in the hospital, as if they understood each other.
Mother kept watch at his bedside with almost no sleep. Hiroko, my sister-in-law, kept
rubbing his hand and leg gently, hoping that he would react. I still vividly remember thedays when all family members came together simply for the recovery of Father.
I now feel that Father is asking us bereaved how we will live and support eachother from now on. His existence within us will never change, as he always taught us
the guidelines for our life.
Since Father’s death, my husband has been making efforts, although he is facedwith various problems. But I believe that he started moving forward, step by step, toanswer the questions Father posed. I will brace myself and make efforts together withhim. This is what I have been thinking about these days.
