English: Later, Naomasa was promoted to Taishin (great feudal lord) of the family when Ieyasu moved to Kanto, while Shigetsugu was given only 3000 koku crop yields.
Japanese: 年が下って家康が関東に移ると直政は家中一の大身となったのに対し、重次は3000石しか与えられなかった。
English: And Naomasa, who had now become Taishin (great feudal lord), blatantly said, "I managed to become Taishin because I served as well as a fine horse, even though you treated me like a fool, calling me brat or something, when the lord gave me that famous horse. It was you who were blind," when he met Shigetsugu.
Japanese: そして、大身になった直政は重次と顔を合わせた時、「昔、殿が名馬を下さった時に子倅だの何だのと馬鹿になされましたが、このような大身になれたのは、名馬に違わぬ働きをしたからでございます。目が暗かったのは本多殿の方でありましたな」と言い放った。
English: From that episode, it is clear that Naomasa either held grudges easily about what people said about him, or he was a person who hated to lose ('II Nenpu' (The Chronological List of Main Events of the Ii clan)).
Japanese: このことから、直政は人に言われたことをすぐ根に持つタイプ、すなわち負けず嫌いであったということが分かる（「井伊年譜」）。
English: Takakage KOBAYAKAWA, who was a senior vassal of the Mori clan, once praised Naomasa's military prowess and political ability by saying, "Even though Naomasa is from a low status family, he has the potential to become the ruler of the world'.
Japanese: 毛利家の重臣である小早川隆景は直政の武勇・政治的手腕に関して「直政は小身なれど、天下の政道相成るべき器量あり」と評価したことがある。
English: That meant Naomasa could the take reins of government if he wanted (not only Takakage but also other busho of the provinces whispered the same thing).
Japanese: これは直政がその気になれば、天下を取ることもできるということを意味している（隆景だけでなく、地方の武将達も同じようなことを噂していた）。
English: However, it is said Nomasa never expressed such ambition in his life.
Japanese: しかし、生涯直政にそのような野心を見せる様子はなかったと言われている。
English: Ii's Akazonae (red arms) were renowned around the country as the most elite force among Sengoku (warring provinces) during the Azuchi Momoyama Period, however, there seem to have been many vassals who couldn't stand the strict military discipline of Naomasa and left to serve Tadakatsu HONDA instead.
Japanese: 井伊の赤備えは、戦国屈指の先鋭部隊として安土・桃山時代の初期から末期にかけて天下に名を轟かせていたが、家臣達の中には直政による厳しい軍律に耐えられなくなり、本多忠勝の下に去る者達も多かったという。
English: Even Morikatsu KIMATA, who was the Hitto karo (head of the chief retainers), became terrified of serving under Naomasa, and asked Ieyasu to reinstate him in his former position as a hatamoto (bannerman).
Japanese: 筆頭家老である木俣守勝ですら、直政の下にいるのが怖くなり、家康に旗本に戻してくれるように頼んだといわれている。
English: Naomasa is regarded as one of the wise rulers of the Ii clan for reviving the once moribund clan, and developing it into the head of the fudai daimyo (a daimyo in hereditary vassal to the Tokugawa family) in the Edo Shogunate.
Japanese: 直政は一時期滅亡していた井伊氏をわずか一代で再興させ、さらに江戸幕府の譜代大名の筆頭にまで成長させた井伊氏の英雄とされているため、井伊氏の名君の一人と言われている。
English: Naomasa won Hideyoshi's confidence and was his favorite baishin (indirect vassal) among the vassals of the Tokugawa clan, however, one theory has it that Naomasa himself didn't much like Hideyoshi.
Japanese: 直政は徳川氏の家臣の中で秀吉から最も気に入られていた陪臣であったため、秀吉からも厚い信頼を受けていたが、一説では、直政自身は秀吉をあまり快く思っていなかったとも言われている。
English: It is said this was because after Odawara no Jin (The Siege of Odawara) Hideyoshi suddenly confiscated the five territories Ieyasu had spent decades gaining the hard way (Mikawa, Totomi, Suruga, Kai and Shinano provinces), and gave him seven former Gohojo clan territories (Musashi, Izu, Sagami, Kozuke, Shimotsuke, Kazusa and Shimousa provinces) instead, which Naomasa regarded as unsatisfactory.
Japanese: その理由は、小田原の陣の後、突然、秀吉が家康が何十年間も苦労して手に入れた三河国、遠江国、駿河国、甲斐国、信濃国の5カ国の領地を没収して、その代わりに後北条氏の旧領である武蔵国、伊豆国、相模国、上野国、下野国、上総国、下総国の7カ国に移封したことを不満に思っていたためだと言われている。
English: It appears that not only Naomasa, but also other vassals of Ieyasu complained about this.
Japanese: また、直政だけでなく、他の家康の家臣も同じようにこのことを不満に思っていたとされている。
English: Naomasa was given the 180,000 koku crop yield Sawayama, Omi Province after the Battle of Sekigahara, however, this did not satisfy him because Sawayama was a former territory of Mitsunari ISHIDA, whom Naomasa disliked, so he asked Ieyasu to allow him to Takasaki, Kozuke Province.
Japanese: 関ヶ原の戦いの後、直政は近江国佐和山18万石を与えられたが、自分が嫌っていた石田三成の旧領であったため、直政自身はあまり納得しておらず、家康に上野国高崎に戻してもらうように頼んだという。
English: Despite his great ability in both military and political matters, Naomasa didn't earn his place in history (that is not to say he is completely unheard-of).
Japanese: 直政は武力と政治的手腕の両方ともにかなりの実力を有していたにもかかわらず、後世にその名があまりしられていない（かと言って、全く無名というわけでもない）。
English: It is said the reason was that Naoyasu was so loyal to Ieyasu that he became too strict with his vassals, and this worked against him.
Japanese: その理由は直政が家康に対して忠義を篤くしすぎて、あまりにも家臣達に厳しくなってしまったことが裏目に出てしまったのではないかと言われている。
English: Even though it was normal in samurai society for vassals to follow their master to the grave, no vassals followed Naomasa when he died,
Japanese: 武家社会において、主君が亡くなった時に家臣が殉死することは当たり前であったが、直政の死に従う者は一人もいなかったという。
English: Naomasa was always injured in battles despite being heavily-armored, while Tadakatsu HONDA, who wore light armor, was never injured in the 57 battles he joined in his life.
Japanese: 生涯に参加した57回の戦で軽装備であったにもかかわらず、一度も傷を負わなかった本多忠勝に対して、直政は重装備であったが、戦で常に傷を負っていたという。
English: In addition to his love of fighting in the front line and his own fierce disposition, it is said he had no other way to make his name renowned around the country (it is also said that he didn't care about being injured in battle in order to avoid being envied by other vassals on account of him being treated as a senior vassal despite being so young, and to make the other vassals understand his efforts).
Japanese: 先陣で自ら戦うのを好む直政自身の激しい性癖によるところも大きいが、自分の存在を天下に轟かせるためには、こうするしかなかったとも言われている（直政は自分が若いにもかかわらず家康に重臣として扱われることで周囲からの嫉妬や妬みの対象にならないようにするために、戦で戦傷を負うのを厭わず、それによって自分の苦労を他の重臣達に理解してもらおうとしていたとも言われている）。
English: Naomasa fought 16 battles in his life, and it is said he was never defeated (the Ii Akazonae [red arms] were defeated by the Akazonae of Nobushige SANADA in the Osaka Fuyu no Jin [The Winter Siege of Osaka]).
Japanese: 一方で生涯に参加した戦は16回であり、いずれの戦でも直政が負けたことは一度もないと言われている（井伊の赤備え自体は大坂冬の陣で真田信繁率いる赤備えと戦って敗北している。
English: It is said Naomasa and Tadakatsu were on bad terms because they were rivals and were often compared with each (according to some documents, only Tadakatsu saw Naomasa as a rival).
Japanese: また、上記のように直政と忠勝は度々比較の対象となったりすることがあり、この2人はお互いにライバル同士であったため、あまり仲がよくなかったと言われている（記述によっては忠勝だけが直政をライバル視していたとされることもある）。
English: It is also said that at first Naomasa was not on good terms with Yasumasa SAKAKIBARA, who was the same age as Tadakatsu, however, it seems they became closer through acting together after Ieyasu entered Kanto.
Japanese: なお、忠勝と同年齢の榊原康政とは、最初はあまり仲がよくなかったと言われているが、家康が関東に入国してから共に行動をすることが多くなり、段々と仲がよくなっていったとされている。
English: It is said Tadatsugu SAKAI, Ieyasu's Hitto karo (head of the chief retainers), looked favorable on Naomasa in the same way as Ieyasu.
Japanese: 家康の筆頭家老である酒井忠次も家康と同じように直政に対して暖かい目で見守っていたと言われている。
English: Tadatsugu reprimanded Yasumasa for that out of jealousy when Naomasa had just become the head of an army.
Japanese: ちなみに忠次は直政がまだ一軍の将になったばかりの頃に康政がそのことを妬んだために叱ったことがある。
English: On one occasion, Ieyasu gathered Naomasa's vassals in one place, made Naomasa take off his clothes, and, with tears in his eyes, explained each injury left on Naomasa's body to them (it is said Ieyasu always cared about Naomasa's being injured in battle).
Japanese: ある時、家康は直政の家臣達を1つの場所に集めて、直政の衣服を脱がせて体に残っていた戦傷の一つ一つを涙ぐみながら説明したという（家康は直政が常に戦で戦傷を負うことをいつも気にしていたという）。
English: It is said upon hearing this, Naomasa's vassals cried in sympathy with Ieyasu and determined to do their best in battle for their lord Naomasa.
Japanese: このことを聞いた直政の家臣達も家康を見てもらい泣きをし、自分達も主君である直政のために全力で武功を挙げようという決意をしたと言われている。
English: It appears that Naomasa's ability in politics was well known among the vassals of other clans, because after the Battle of Sekigahara he was asked by Yoshihiro SHIMAZU, who was a member of the Western Camp, to serve as mediator with Ieyasu for peace talks (even though Masanobu HONDA, whose specialty was politics, was among the vassals of the Tokugawa clan).
Japanese: 関ヶ原の戦いの後、直政は西軍の一員であった島津義弘から家康との和平交渉の仲立ちを依頼された（徳川氏の家臣の中に政治を専門とする本多正信がいるにもかかわらず）ことからその政治的手腕は、他家の者達に知れ渡っていたと思われる。
English: It is said Ieyasu sometimes consulted Naomasa because he was thoughtful and discreet.
Japanese: 直政は思慮深く、口重であったため、度々家康の内々の相談相手になっていたと言われている。
English: Therefore, Ieyasu, who rarely praised others, thought highly of Naomasa saying 'Naomasa gives his opinion when nobody else will'.
Japanese: そのため、他人を評価することがめったにない家康は、直政のことを「余人がいない時に直政が意見を出してくれる」と高く評価している。
English: Along with Kazumasa ISHIKAWA, Naomasa made a significant contribution as a diplomat, of which there were few among the vassals of the Tokugawa clan, and, along with Masanobu HONDA, was regarded by Ieyasu as a man of wisdom needed to take the reins of government.
Japanese: 直政は石川数正と並んで徳川氏の家臣の中でも数少ない外交官として、大いに力を発揮し、また、家康から見て本多正信と並んで天下取りの知恵袋とされていた。
English: It is said the reason Naomasa was assigned as a Hyobu-shoyu (junior assistant minister of the Hyobusho Ministry of Military) was that Toramasa OBU, a vassal of the Takeda clan who had first organized the Akazonae (red arms), had been assigned as one.
Japanese: なお、直政が兵部少輔に叙任されたのは、最初に赤備えを組織した武田氏の家臣である飯富虎昌が兵部少輔に叙任されていたためだとも言われている。
English: It is not widely known that Naomasa was such a submissive husband to his lawful wife Tobaiin that he could not fight with her, even though he hated defeat more than anyone.
Japanese: あまり知られていないことだが、直政は正室である唐梅院に対してはかなりの恐妻家で、誰よりも負けず嫌いであった直政もこの唐梅院だけには頭があがらなかったという。
English: Naotaka, Naomasa's second son, was born to a waiting woman of Tobaiin, however, Naomasa did not try to meet him for about 10 years after his birth.
Japanese: 直政の次男である直孝は唐梅院の侍女を母に産まれたとされるが、直政は直孝の誕生後、十年近くも対面しようとしなかった。
English: After the battle of Sekigahara, he moved his territory away from Edo and disappeared from the main stage of history.
Japanese: 関ヶ原の戦いの後、江戸から離れた領地に移封されて政治の表舞台からも姿を消している。
English: According to one theory, Naomasa was given cold shoulder by Ieyasu because of his great achievements in the past, however, another theory that he could not have served due to tetanus caused by the wound he received at the Battle of Sekigahara is widely accepted.
Japanese: かつての功績があまりにも大きいため家康に冷遇されたとも言われるが、直政は関ヶ原の戦いでの戦傷が元で破傷風を起こしているため病気で出仕できなかったとの見方が大勢である。
English: He was a member of the Imagawa clan, a branch family of the Kira clan that was in a collateral line with the Ashikaga clan originating from the Kawachi-Genji (Minamoto clan), which was one of the Seiwa-Genji (Minamoto clan originated from the Emperor Seiwa).
Japanese: 家系は清和源氏の一家系・河内源氏の流れを汲む足利氏の傍流吉良氏の分家にあたる今川氏。
English: He demonstrated an outstanding ability in management of his own territory as well as in outward military expeditions, and he succeeded in transforming the head of the Imagawa clan into a Sengoku daimyo, expanding his territory from Suruga Province, Totomi Province and Higashimikawa (eastern part of Mikawa Province) to Nishimikawa (west part of Mikawa Province), even reaching into a part of Owari Province.
Japanese: 領国経営と外征の双方に才能を発揮し、今川氏の戦国大名への転身を成功させ、所領も駿河・遠江国・東三河から、西三河や尾張国の一部にまで拡大した。
English: However, during a military offensive in Owari Province, Nobunaga Oda's army made a surprise attack on Yoshimoto in the Battle of Okehazama and he died in battle.
Japanese: しかし尾張に侵攻した際に桶狭間の戦いで織田信長軍の奇襲により戦死した。
English: As a result, Yoshimoto was sent to the Zentoku-ji Temple of the Rinzai Sect in Seko, Fuji County, Suruga Province and became a priest at the age of four.
Japanese: そのため、4歳で仏門に出されて臨済宗の駿河富士郡瀬古の善徳寺に預けられた。
English: He was called Sengaku Shoho (the reading of Baigaku Shoho was inaccurate), and in order to study at Kyoto Gozan (the five selected temples in Kyoto), he went up to Kyoto accompanied by the Zen priest Sessai TAIGEN, a chief retainer of the Imagawa family and assigned to serve Yoshimoto as a tutor.
Japanese: 栴岳承芳（せんがくしょうほう（梅岳承芳（ばいがくしょうほう）は誤伝））と称し教育係につけられた今川家重臣出身の禅僧・太原雪斎とともに京都に上って五山に学んだ。
English: When Ujiteru suddenly died in 1536, Yoshimoto came to be involved in the family succession dispute with Etan GENKO, Yoshimoto's older paternal half-brother who was also in the priesthood, and Yoshimoto, who finally won the dispute due to Sessai's intensive efforts, quit the priesthood and took over the position of the ninth family head of Imagawa clan as well as the shugo in Suruga Province, and began calling himself Yoshimoto (Hanakura Rebellion).
Japanese: 天文(元号)5年（1536年）、氏輝が急死したために駿河に戻り異母兄で同じく出家していた玄広恵探との間で家督争いとなるが、雪斎の尽力で勝利し、還俗して今川氏第9代当主・駿河守護となり、義元と称した（花倉の乱）。
English: In March 1537, Yoshimoto created an alliance with the Takeda clan, whom with the Imagawa family had been in a long state of war until the Ujiteru's generation, by taking the daughter (Joein) of the Shugo in the Kai Province named Nobutora TAKEDA, as his lawful wife (Kosun Alliance [an alliance between the Takeda clan in Kai Province and the Imagawa clan in Suruga Province]).
Japanese: 天文6年（1537年）2月、氏輝期までの抗争状態にあった甲斐国の守護武田信虎の娘（定恵院）を正室に迎え、武田氏と同盟を結んだ（甲駿同盟）。
English: Establishment of the Kosun Alliance lead to the break of the Sunso Alliance (Suruga-Sagami alliance), an alliance that had been with a long time relative family, the Gohojo clan, who were dominating the provinces of Izu (Izu region, Shizuoka Prefecture) and Sagami (southwest part of Kanagawa Prefecture), resulting in Ujitsuna HOJO setting out for a military invasion into Yoshihara of Kato County in Suruga Province (Kato War).
Japanese: 甲駿同盟の成立は旧来の縁戚であった伊豆国（静岡県伊豆地方）・相模国（神奈川県西南部）を領する後北条氏との駿相同盟決裂を招き、北条氏綱が駿河河東郡吉原に侵攻する（河東の乱）。
English: Additionally, Nobuhide ODA of Owari Province (western part of Aichi Prefecture) began invading Mikawa Province (eastern part of Aichi Prefecture) in 1540.
Japanese: さらに、尾張国（愛知県西部）の織田信秀が天文9年（1540年）から三河国（愛知県東部）に対して侵攻を開始する。
English: Although Yoshimoto challenged Nobuhide to a decisive battle in 1542 by counting on an alliance with various local ruling families in Mikawa Province, he was defeated by Nobuhide's intensive attack (the First Battle of Azuki-zaka).
Japanese: このため、義元は三河の諸豪族と連合して天文11年（1542年）に信秀と一大決戦に臨むが、その猛攻の前に敗れた（第1次小豆坂の戦い）。
English: However, there is another theory that this battle is fictitious and there was only a Second Battle of Azuki-zaka in real history.
Japanese: ただしこの戦いを創作とする説もあり、その場合は第2次小豆坂の戦いのみが存在する事になる。
English: In 1541, Yoshimoto offered asylum to Nobutora TAKEDA, who had been banished by his own legitimate son Harunobu TAKEDA, and accepted him in Suruga Province, but it has also been suggested that Nobutora's banishment might have been carried out in a collusion between Yoshimoto and Harunobu.
Japanese: また天文10年（1541年）には嫡子の武田晴信に追放された信虎を駿河に庇護しているが、この追放劇は義元と晴信が共謀したものではないかとも言われている。
English: While Ujiyasu succeeded the head of the Hojo family after the death of Ujitsuna in 1541, Yoshimoto formed an alliance in 1545 with Norimasa UESUGI, who was also in a warring state with Ujiyasu, and they made a joint attack against Ujiyasu.
Japanese: 北条家では天文10年（1541年）に氏綱が死去し氏康が家督を継いでいたが、義元は氏康と同じく敵対する上杉憲政と天文14年（1545年）に同盟を結んで、連携して氏康を攻めた。
English: As a result, Yoshimoto and Ujiyasu reconciled, due to the mediation of Harunobu TAKEDA (Shingen) with conditions favorable for Yoshimoto, in which it was settled to have the Kato County dominated by the Hojo family returned to the Imagawa family.
Japanese: その結果、義元と氏康は武田晴信（信玄）の仲介により、北条家の河東郡を今川家に返還するという義元に有利な条件で和睦した。
English: Although Yoshimoto was once deprived of Kokuji-jo Castle by Ujiyasu in 1551, he rapidly regained it and defined the border with the Kise-gawa River.
Japanese: 天文20年（1551年）、氏康によって興国寺城を奪われたものの、すぐに奪還して黄瀬川を国境としている。
English: Although Yoshimoto accepted the submission of Hirotada MATSUDAIRA in Mikawa Province, who felt threatened by Nobuhide ODA of Owari Province, in exchange for Hirotada's legitimate son as a hostage Takechiyo (later Ieyasu TOKUGAWA), a kokujin ryoshu (local samurai lord) of Tawara-jo Castle in Mikawa Province (Tahara City, Aichi Prefecture) named Yasumitsu TODA, who was in charge of escorting the hostage, betrayed Yoshimoto and sent Takechiyo to the Oda clan, Yoshimoto's enemy.
Japanese: 三河においても尾張の織田信秀の進出により圧迫を受けた西三河の松平広忠の帰順を受け、広忠の嫡男・竹千代（のちの徳川家康）を人質に迎え入れようとするが、護送を請け負った三河・田原城(三河国)（愛知県田原市）の国人領主・戸田康光が裏切って護送中の竹千代を敵方の織田氏に送り届けてしまった。
English: Yasumitsu did so because of his indignance for Yoshimoto destroying Toda clan members Norinari TODA and Yoshimitsu TODA a year earlier, and he declared a rebellion against Yoshimoto as the head of Soke (the head family) of the Toda clan.
Japanese: これは、前年に義元が戸田氏の一族である戸田宣成、戸田吉光を滅ぼしたため、これに憤った戸田宗家の当主であった康光が反乱を起こしたものであった。
English: An angered Yoshimoto destroyed Soke of the Toda clan and had the Asahina clan move into the Toda family's Tawara-jo Castle.
Japanese: これに怒った義元は戸田宗家をも滅ぼし、その居城であった田原城に朝比奈氏を入れた。
English: In 1548, sensing danger at Yoshimoto's invasion into the Mikawa Province, Nobuhide ODA set out to attack Yoshimoto, but the Imagawa army, lead by major captains such as Yoshimoto's chief retainers Sessai and Yasuyoshi ASAHINA, made a clean sweep victory against the Oda army, almost eradicating the influence of the Oda family from Mikawa Province (the Second Battle of Azuki-zaka).
Japanese: 天文17年（1548年）、義元の三河進出に危機感を覚えた織田信秀が三河に侵攻してくるが、義元の重臣である雪斎・朝比奈泰能らを大将とした今川軍は織田軍に大勝し、織田家の勢力を事実上三河から駆逐した（第2次小豆坂の戦い）。
English: When Hirotada MATSUDAIRA died in 1549, Yoshimoto sent the Imagawa army to Okazaki-jo Castle (Okazaki City, Aichi Prefecture) and practically took over the Matsudaira family's territory and placed its kokujin ryoshu (local samurai lords) under his immediate authority.
Japanese: 天文18年（1549年）、松平広忠が死去すると義元は今川軍を岡崎城（愛知県岡崎市）に送り込んで、事実上松平家の所領とその支配下にあった三河の国人領主を直接支配下に取り込んだ。
English: He also attacked the Oda clan's Mikawa Ansho-jo Castle (Anjo City, Aichi Prefecture), captured Nobuhide's first bastard child and the castle commander Nobuhiro ODA and used him to retrieve Takechiyo in exchange for the hostages.
Japanese: また、織田方の三河安祥城（愛知県安城市）を攻略し信秀の庶長子にあたる城将・織田信広を捕らえ、人質交換によって竹千代を奪還。
English: When Nobuhide ODA died in 1551, Yoshimoto further accelerated an offensive movement into the Owari Province.
Japanese: 天文20年（1551年）に織田信秀が死去すると尾張への攻勢を一段と加速させる。
English: In addition, in 1553 Yoshimoto revised the Imagawa Kana Mokuroku (the Imagawa clan's basic house law to control the territory), enacted by his deceased father Ujichika, and expanded on it by adding articles collectively referred to as the Kana Mokuroku Tsuika (Expanding on the house rules left by Ujichika), in which he declared abolition within his territory of shugoshi funyu chi (the bakufu-owned area within a feudal lord's territory where access was restricted even for the feudal lord authorized as shugo) instituted by the Muromachi bakufu (Japanese feudal government headed by a shogun), and definitively cut off relations between the Imagawa clan as a Shugo daimyo and the Muromachi bakufu, even though this relationship had barely persisted until then.
Japanese: 更に天文22年（1553年）には亡父の定めた今川仮名目録に仮名目録追加を加えたが、ここにおいて室町幕府が定めた守護使不入地の廃止を宣言、守護大名としての今川氏と室町幕府間に残された関係を完全に断ち切った。
English: In 1554, Yoshimoto arranged a marriage between his legitimate son Ujizane and the daughter of Ujiyasu HOJO (Hayakawadono), tying his family to the Takeda clan as well as the Hojo clan, and formed the Ko So Sun Sangoku Domei (alliance between three provinces; Kai, Sagami and Suruga) (this negotiation is also called the 'Tripartite alliance of Yoshimoto IMAGAWA, Ujiyasu HOJO and Shingen TAKEDA').
Japanese: 天文23年（1554年）、嫡子・氏真に北条氏康の娘（早川殿）を縁組し、武田氏・北条氏と互いに婚姻関係を結んで甲相駿三国同盟を結成した（この会談は善徳寺の会盟とも呼ばれている）。
English: In the Battle of Kawanakajima that broke out in 1555, Yoshimoto mediated between Harunobu TAKEDA and Kagetora NAGAO and achieved reconciliation between the two.
Japanese: また天文24年・弘治元年（1555年）に行われた川中島の戦いでは武田晴信と長尾景虎の仲介を行って両者の和睦を成立させた。
English: After Yoshimoto's prominent assistants successively died of illness, such as his strategist Sessai dying in 1555 and Yasuyoshi ASAHINA in 1557, the Imagawa family gradually began to weaken after living at the height of its prosperity.
Japanese: 弘治(日本)元年（1555年）に軍師・雪斎、弘治3年（1557年）には朝比奈泰能といった名補佐役が次々と病死し、次第に今川家の全盛期に翳りが見え始める。
English: In order to save the Otaka-jo Castle in the Chita County (present Otaka, Midori Ward, Nagoya City), which had been trapped by the presence of the Oda side, he ordered Ieyasu TOKUGAWA and other commanders to take control of the forts of the Oda side located in the vicinity of Otaka.
Japanese: 織田方に身動きを封じられた同国知多郡大高城（名古屋市緑区(名古屋市)大高）を救うべく、大高周辺の織田方諸砦を徳川家康などに落とさせる。
English: As he received notice that his army auspiciously won the preliminary skirmish, he decided to move his main unit that had been stationed at Kutsukake-jo Castle to Otaka-jo Castle.
Japanese: 幸先良く前哨戦に勝利した報せを受けて沓掛城で待機していた本隊を大高城に移動させる。
English: However, when he and his troops took a rest at Mt. Okehazama on the way to the castle, they were attacked by Nobunaga ODA, and even though Yoshimoto fought hard with Soshin MATSUI, he was decapitated by a vassal of the Oda family named Yoshikatsu MORI, and his favorite long sword inscribed Sozasamonji was taken.
Japanese: ところがその途上、桶狭間（おけはざま）山で休息中に織田信長の攻撃を受け松井宗信らと共に奮戦するも、織田家家臣・毛利良勝に愛刀・宗三左文字の太刀ともども首級を奪われた。
English: (This battle is commonly referred to as 'The Battle of Okehazama,' according to "Shincho Koki" [Biography of the Warlord Nobunaga ODA].)
Japanese: （通称「桶狭間の戦い」、『信長公記（しんちょうこうき）』の記述による）。
English: Afterwards, surviving soldiers of the Imagawa side tried to bring Yoshimoto's body back to Sunpu (Shizuoka City), but his headless corpse suffered from considerably rapid decomposition and was buried in Hoi County, Mikawa Province.
Japanese: その後、残存した今川兵によって駿府（静岡市）まで連れ帰ろうと試みられた首の無い義元の遺体は想像以上に腐敗の進行が早く、三河国宝飯郡に埋葬された。
English: Burial mound: Daisho-ji Temple in Ushikubo-cho, Toyokawa City, Aichi Prefecture (Do-zuka [trunk tomb]) (next to the grave of Tokiie ISSHIKI).
Japanese: 塚：愛知県豊川市牛久保町の大聖寺(豊川市)（胴塚）（一色時家の墓の隣）。
English: Yoshimoto's severed head was later returned to the Suruga Province along with negotiations for surrender of the castle held by Yoshimoto's chief retainer Motonobu OKABE, who continued to fight bravely at Narumi-jo Castle against Nobunaga.
Japanese: 織田方に討ち取られた首級は、鳴海城に留まり奮戦する義元の重臣・岡部元信と信長との開城交渉により後に返還され、駿河に戻った。
English: After Yoshimoto's death and his legitimate son Ujizane IMAGAWA succeeded the family reign, Motoyasu MATSUDAIRA (later Ieyasu TOKUGAWA) declared independence in Nishimikawa (western part of Mikawa Province), taking advantage of the unguarded moment.
Japanese: 義元の戦死により家督は嫡男の今川氏真が継いだが、この隙に乗じた松平元康（後の徳川家康）が西三河で自立。
English: In Higashimikawa (eastern part of Mikawa Province), the Toda clan, the Saigo clan and others seceded from the Imagawa clan as well following Motoyasu's move, and became affiliated with the Matsudaira clan.
Japanese: この動きに追従するように東三河でも戸田氏や西郷氏などが離反、松平氏の傘下へ転属していく。
English: Once the unrest in Mikawa Province was transmitted to the neighboring Totomi Province, the whole territory became wrapped in suspicion with people in panic wondering who would be friend or foe amid the chaos and whether the news was true or false (Enshu [Totomi Province] Confusion).
Japanese: このような三河の動揺が隣国・遠江へも伝播すると、正・誤の判別がつかない情報が飛び交う遠江領内は敵味方の見極めさえ困難な疑心暗鬼の状態に陥ってしまう（遠州錯乱）。
English: Although Ujizane, who had very limited ability to control the minds of the people, thought he could cool down the situation by purging Naochika II and Tsuratatsu (連竜) IIO, their purge had the opposite effect and accelerated the estrangement of the people and the Imagawa clan began a drastic decline.
Japanese: 氏真は人心を掌握する才能に乏しく井伊直親や飯尾連竜などの粛清で事態の収拾を期したが、かえって人心の離反を加速させてしまい今川氏は見る見るうちに衰退し始めた。
