Towards building a startup ecosystemthat solves the challenges facing thehealthcare industry, and contributes
to the achievement of SDGs

Hiroshi Igahara
Executive Officer cum General Manager,
MD Business Division“Make Yokowo a good company.” This phrase isalways being repeated by Yokowoʼs President
Takayuki Tokuma, and represents guiding principles
for officers and employees when making daily
management and business decisions.
At Yokowo, we started our Medical Devices
business in 2006. The key leader in starting up thisbusiness was President Tokuma, who was at the timeworking as an officer in charge at the Management
Planning H.Q. for new businesses. This includes astrong desire to link our core technologies directly to
making a contribution to society. In 2017, I was
appointed to the position of General Manager of the
MD Business Division. While contributing to society
through our business, I wanted every single employee
to feel a sense of fulfillment in playing their parts.
At the same time, I realized the difficulty of achieving
this on our own.
It was at this juncture that we met Kazuya
Shobayashi, the CEO of Biomedical Solutions Inc. In
exchanging opinions with Mr. Shobayashi about the
medical industry in Japan, we shared issues such as
Japan lagging behind in developing medical device
ventures, and Japanʼs medical industry being heavily
dependent on imports̶we agreed to work together
in order to resolve these issues.
During our discussions, in which I included stories
of my own experience in start-up business investment
and M&A, Mr. Shobayashi presented a proposal for astartup ecosystem as a framework for the domestic
development of medical devices at the Council for

Promotion of the Next-Generation Medical Equipment
Development sponsored by the Cabinet Secretariat in2018. In full agreement with this, Yokowo has
assumed a role as the manufacturing partner in thisventure in order to bring these innovative productideas to reality.
With Mr. Shobayashi, universities, and venture
capital developing the vision and concepts, they havecome up with plenty of product ideas, centeredaround innovative developments, with many related
to the treatment of rare diseases. For Yokowo, 2020
has already seen cooperation started with three
medical device startups (investment completed in two,and under consideration in one), and we plan to begin
cooperation with several more companies within theyear. At present, this initiative is situated as animportant part of our future strategy for our Medical
Device business.
Regarding this initiative, we have heard from anexternal director that “startup ecosystems arefundamental to SDGs,” and from many members ofbusiness divisions that they felt they were contributing
to society more than as in their daily business, and thatthese gave them a sense of fulfillment. For myself, I am
convinced that these initiatives will help bring aboutboth a better company, and a better society.
Looking forward, while working together withvarious parties in the medical industry, I am
determined to fulfill my responsibilities as the leaderof the business in contributing to bringing this startup
ecosystem to success.

Main R&D Themes

Based on the Yokowo Groupʼs company-wide growth strategy,
the R&D department, the business divisionʼs technology
department, and local development centers work together topromote research and development centered on the Companyʼscore technologies. In particular, Yokowo is focusing on the
research and development of new technologies and new
products with an emphasis on developing products with a higher
degree of technological integration and increased added value.
In the fiscal year ended March 31, 2020, Yokowo invested
3.59 billion yen in research and development, and plans towholeheartedly strengthen its R&D activities in the next fiscal
year and beyond.

Over the medium to long term, Yokowoʼs main markets,
namely the automotive, semiconductor testing, mobile
communication terminals, and medical device markets, areexpected to grow in size due to: advances in new eco-friendly
vehicles such as plug-in hybrids and electric vehicles as well as
advanced driver-assistance systems (ADAS) and automateddriving; the actualization of new semiconductor demand fornext-generation high-speed, large-capacity communications
typified by 5G; the rise of next-generation products such as
wearable devices; and the spread of minimally invasive
treatment and advances in genetic testing technology.
The main R&D themes for each segment related to the above
markets are as follows:▼ R&D expenses
