武田信玄（1521年12月1日－1573年5月13日、大永元年十一月三日－元龜四年四月十二日，原名武田晴信，通稱太郎）是日本戰國時代的大名，為清和源氏源義光的代，甲斐武田第19代督，武田信虎之長子。母親是甲斐國人衆大井信達的女兒大井之方，正室為扇上杉大名上杉朝興之女，繼室為左大臣三條公賴之女三條之方。官位是從四位下大膳大夫、信濃守，大正時代贈從三位。

武田信玄外號“甲斐之虎”，所舉“風林火山”之軍旗語出《孫子兵法》，成武田軍的一種象徵。

經

幼年

武田信玄於1521年12月1日出生於躑躅崎館，幼名一千千秋代，乃是甲斐國大名武田信虎的長男。1533年，信虎替其迎娶上杉朝興的女兒作為正室，於次年懷孕，卻因難産而死。信虎又在1536年請托室町幕府第12代將軍足利義晴賜下偏諱，改其名為武田晴信，敘任從五位下大膳大夫，同年晴信迎娶第二任正室三條夫人。1536年11月，晴信初陣，攻陷佐久郡海之口城，殺其城主平賀源心（但此事僅見於甲陽軍鑒，真實性仍待考究）。1541年信虎與村上義清、諏訪賴重力攻打小縣郡，矢澤氏投降，但海野棟綱及真田幸隆逃亡到上州。

繼承督

1541年6月，晴信聯同垣信方、甘利虎泰、飯富虎昌等人趁信虎出訪駿河國時，動兵變自立，逐信虎於駿河。放逐的原因‘甲陽軍鑒’以及‘????山嶽奄小年代記’的記載是父親實行暴政，激起人民不滿。當晴信繼位時，受到當地的人民熱烈歡迎。

早期多信‘甲陽軍鑒’的說法，認為武田信虎是在天文七年，即1538年被放逐，但佐以‘妙法寺記’、‘高白齋記’等書，武田信虎被放逐的年份，應為天文十年，即1541年。

平定信濃

晴信放逐父親的消息傳開，諏訪郡上原城主諏訪賴重以及林城城主信濃守護小笠原長時聯手進攻甲斐，結果被晴信擊退（韭崎之戰），而續又有木曾、小笠原、諏訪跟村上義清四聯軍來攻，又再度被晴信擊退（瀨澤之戰），不過這兩場戰事在近代考證中，參照‘妙法寺記’、‘高白齋記’等書全無紀錄，因此很可能都是‘甲陽軍鑒’所編造。

1542年6月，晴信决定攻打妹夫諏訪賴重，當時晴信聯諏訪氏支族的高遠賴繼對諏訪進行攻擊，諏訪賴重戰敗自身亡。其高遠賴繼因不滿領地分配問題與晴信對立，攻破小澤淵。

1543年進攻信濃國長窪城，大井貞隆自身亡。1545年4月晴信攻打高遠賴繼的高遠城，於6月擊敗撃破高遠賴繼及福與城主藤澤賴親統率的軍隊。

1546年，晴信進攻佐久郡，占領內山城及前山城。

1547年，晴信進攻志賀城的笠原清繁，但在上杉憲政支援下陷入苦戰。8月6日，晴信在小田井原之戰中大敗聯軍，卻在戰不容許敵軍投降，更殺所有敵軍，將3000首級懸於地墻上，又對人質作出酷刑，俘虜欲贖自由時更開出高達2～10貫的身代金，高過20～30文錢的一般價格，故意讓俘虜無法鄉而被武田充入黑川金山當奴工，這為晴信統一信濃的過程增添麻煩。同年，晴信參考《今川假名目錄》、《朝倉敏景十七個條》、《大內壁書》等書籍，創立武田氏的分國法——“甲州法度次第”（又稱武田法）。

1548年2月，晴信進攻信濃國北部的村上氏，村上義清在上田原迎擊，兩軍正面交鋒，武田軍卻占下風，陣亡者包括甘利虎泰、垣信方等大將，是為“上田原之戰”。晴信在戰於湯村溫泉休養30天。小笠原長時趁機於4月進攻諏訪，7月，晴信在????尻峠之戰大敗小笠原軍。

1550年7月，晴信進攻小笠原氏的領地，迫近林城，長時無法抵擋晴信的入侵放棄林城，逃到村上氏領地，中信濃落入武田勢力。9月，晴信村上氏領地進軍，備攻擊砥石城，戰況對武田軍不利，晴信失去橫田高等將領。當晴信聽說葛尾城的主力接近，武田軍在增援到達前撤兵。1551年，晴信部下真田幸隆利用謀略，成功占據砥石城。1553年義清放棄葛尾城，逃往越，依靠長尾景虎，拉開川中島會戰的序幕。

三國同盟與川中島之戰

1553年，在村上義清長尾景虎的提議下，長尾軍川中島進軍，長尾軍和武田軍在信濃川中島對峙，但兩軍沒有積極行動，5月兩軍撤退。是為第一次川中島之戰。

1555年，晴信嫁給今川義元的姐姐定惠院病逝，為延續與今川的同盟，晴信遂為嫡男義信迎娶義元的女兒，將愛女嫁給北條氏政，北條氏康也將女兒嫁給今川氏真，甲相駿同盟於焉正式成立。

1555年，與長尾軍在川中島對峙，是為第二次川中島之戰，在今川義元的介入下，兩軍從川中島撤退。同年晴信平定木曾義康和木曾義昌兩父子。

1557年，武田軍和長尾軍再次在川中島對峙，但是沒有交戰，上杉軍因越中一揆出兵而撤退。

1559年5月，晴信出，法名德榮軒信玄。

1561年9月10日，第四次川中島會戰爆，雙方動員超過一萬兵力參戰，最終信玄成功擊退上杉軍，不過卻損失其弟信繁、諸角虎定、山本勘助及三枝守直等人。

1564年，上杉軍和武田軍主次再次在川中島對峙，不過兩軍沒有交戰而退兵，是為第五次川中島之戰。

入侵關東、東海

武田信玄多次派兵進攻上野國，逐步擴大在上野的勢力圍，但箕輪城守將長野業正仍持續頑抗。1561年（永祿4年），業正病逝，由兒子長野業盛繼承。信玄在1566年（永祿9年）派遣2萬大軍攻打箕輪城。武田軍成功攻入箕輪城，業盛自身亡，武田的勢力延伸到上野國西部。

1565年（永祿7年）武田信玄派遣山縣昌景聯北飛驒豪族江馬氏打敗三木氏攻下飛驒，在隔年以江馬氏攻入越中，勸降倉城主椎名氏，拿下越中新川郡地山城周遭，遂以江馬時盛嫡子輝盛擔任城主，但此說雖見於甲陽軍鑒，但參考“興寺文書”跟“上杉年譜”，椎名康胤反出上杉的時間應該更晚，而江馬時盛跟三木1565年底便又雙雙改投上杉，使武田信玄的飛驒戰略失利。

在德川康與今川氏真翻臉交戰，身為三國同盟之一且作為氏真舅舅的武田信玄卻打算侵入今川，為此不滿的信玄長子武田義信與老飯富虎昌企圖將武田信玄流放，卻被信玄早一步現，武田義信遭到囚禁，最逝世。1568年（永祿11年），武田信玄順利策反上杉臣本莊繁長跟越中豪族椎名康胤（本莊繁長之亂），武田軍也對北信濃的飯山城動攻擊，卻未能攻下城池，而信玄同時通過織田信長和德川氏聯手，以今川氏真跟上杉謙信通好為藉口揮師駿河，三國同盟正式毀滅。隨着今川臣的大量倒戈，今川氏真不敵敗退，武田信玄於薩埵峠大破今川氏真軍，攻入今川館拿下駿河，卻暗中搞小動作，讓臣山信友出兵德川康占領的遠江，因此德川康改與北條氏康聯手抵禦武田軍，武田信玄為防備上杉謙信奧援北條，武田信玄也透過將軍足利義昭和織田信長與上杉進行和談。

1569年（永祿12年）北條氏政出兵駿河，武田信玄出兵支援防備，但同樣在薩埵峠被北條氏政擊退，陣亡數百人，武田信玄透過馬場信春所建議的啄木鳥戰，保全主軍退甲斐，駿河多處城池被北條軍奪（第二次薩埵峠之戰）。同年6月再次遭到北條氏康擊敗，連八幡大菩薩的旗幟都被北條軍奪去，但此戰是否存在也有爭議，欠缺一級史料印證。武田信玄為擊敗北條，也和關東的佐竹義重、見義弘等大名策略聯盟，兩夾擊北條（甲佐同盟）。

同9月信玄率2萬兵馬攻打關東。10月1日包圍小田原城不果，10月4日信玄解除小田原城的包圍，甲斐退卻。10月8日在三增峠之戰跟北條氏邦及北條氏照交戰。1570年信玄重新南下與北條、今川軍交戰，再度成功占領駿河一帶。1571年（元龜2年）北條氏康病逝，完全掌握實權的北條氏政决定放棄與上杉氏的相越同盟，改為與武田氏同盟。

信玄西上

甲相同盟達成，信玄的戰略目標轉三河國德川以及原先友好的織田，於是響應本寺顯如跟朝倉義景的要求加入信長包圍網。武田軍在1572年（元龜3年）10月備進攻織田氏，總兵力達30000（當中包括北條氏政派來的增援）。另外為牽信長出兵增援，派遣臣下條信氏率3000兵進攻美濃國岩村城。

當時信長領內面對石山本寺、朝倉氏、淺井氏等敵對勢力，無暇他顧。10月14日，信玄在一言坂之戰擊敗迎擊的德川軍，接着信玄本隊包圍二俁城，12月19日武田軍攻下二俁城。當信玄迫近濱城的時候，康决定迎擊。12月22日兩軍在三方原交戰，德川的總兵力衹有11000，在戰和士氣方面武田軍占優，最終武田取得大捷（三方原之戰）。武田軍繼續西進，1573年（元龜4年）1月包圍三河國野田城，2月10日武田軍攻占野田城。

病逝

武田信玄、賴之墓

攻下野田城，信玄病情惡化，於三河長篠城休養，行軍因而中止。經過一個月左右信玄的病情沒有好轉，4月武田軍决意返甲斐。4月12日武田信玄病逝於信濃國駒場（今長野縣下伊那郡阿智村），享年五十二歲。《宿監物書狀》提及死因為肺結核，《甲陽軍鑒》指出死因是胃癌及食道癌。信玄的遺在信濃國伊那駒場長嶽寺火化。戒名法性院機山信玄。信玄的墓地分佈在信玄墓、大泉寺、惠林寺、諏訪湖、長嶽寺、竜寺、高野山、福田寺、妙心寺等地。

遺言

甲陽軍鑒版

於五載前，即知此日，特畫花押紙七百，卒三年內，密不喪，其間公文可用之。他國不知死，必不敢動。武田氏由信繼承，信元服前以父賴攝政。加遺骸以梏，沉諏訪湖。

宿監物書狀版

將大去也。出身僻鄉，伏擊鄰國他郡，戰無不。可遺憾者，未能目睹武田旗立之帝都。倘大去消息傳出，敵必蜂擁而起。因之，三、四載內務必嚴守秘密，整頓領土，培養義卒，庶一舉攻都。九泉之下，必當含笑欣慰。

人物

信玄的風林火山之旗

其用兵方略與為政之道在日本戰國史上留下頗具影響的一筆。所舉“風林火山”（其疾如風，其徐如林，侵掠如火，不動如山）之軍旗，語出《孫子兵法》，成為武田軍的一種象徵。

信玄積極開耕地，服甲州耕地不足的問題，尤其窮半生精力修的信玄堤至今仍在揮作用。信玄利用甲州領內大量金礦，積極開採金礦的事業，引入先進的金技術，行全日本最初的定額金幣“甲州金”。信玄重視民政，其定的《甲州法度次第》為戰國時期著名的分國法之一。

信玄曾迷戀擔任小姓的春日源介（通說為高坂昌信，但無法證實），信玄寫給春日的情書仍保留至今。

信玄入侵駿河，積極招攬水軍加入，當中包括間宮武兵衛、間宮造酒丞、小濱景隆、井正綱、伊丹雅、間宮忠兵衛等人。

《完全圖解日本戰國武將54人》記載，信玄的馬桶是衝水式，積為六席，在便器周圍放榻榻米，當面表面反面方面正面迎面滿面封面地面路面世面平面斜面前面下面四面十面一面洗心革面方方面面面貌面容面色面目面面俱到用熏香除臭，清理時是使用洗澡水清理，信玄曾說：草木（和臭同音）不絶，因此稱之為（甲洲山）。

原名武田晴信，信玄是出皇后的法名，《甲陽軍鑒》記載，玄字取自中國唐代名僧臨濟宗創始人臨濟義玄。

Takeda Shingen (武田 信玄, December 1, 1521 – May 13, 1573), of Kai Province, was a pre-eminent daimyō in feudal Japan with exceptional military prestige in the late stage of the Sengoku period.

Name

Takeda Shingen

Shingen was called "Tarō" (a commonly used pet name for the eldest son of a Japanese family) or Katsuchiyo (勝代) during his childhood. When he celebrated his coming of age, he was given the formal name Harunobu (晴信), which included a character from the name of Ashikaga Yoshiharu (足利義晴), the 12th Ashikaga shōgun. It was a common practice in feudal Japan for a higher-ranked warrior to bestow a character from his own name to his inferiors as a symbol of recognition. From the local Lord's perspective, it was an honour to receive a character from the shogunate, although the authority of the latter had greatly degenerated in the mid-16th century.

Both the Ashikaga and the Takeda clans descended from the Minamoto (源) clan. Technically, Harunobu, as well as his forefathers, had borne the surname of Minamoto. Therefore, Harunobu would be referred to as "Minamoto-no Harunobu" (源晴信) in official records kept by the Imperial Court when he was conferred the official title of "Daizen Dayu" (大膳大夫). The Imperial Court had maintained a system of ritsuryō (律令) that was parallel to the shogunate apparatus.

In February 1559 Harunobu chose to live a pabbajja life as a Buddhist novitiate and received a dharma name, Shingen (信玄), from his Buddhist master. The kanji of "Shingen" can also be pronounced as "Nobuharu", which is the inversion of his official name, Harunobu. In ancient times, such religious names of recognized Japanese aristocrats would be read in "on'yomi" (音讀み), the Chinese-style pronunciation, instead of "kun'yomi" (訓讀み), the indigenous Japanese pronunciation. Although widely known by the dharma name, Takeda Shingen's formal name remained "Harunobu" throughout the rest of his life.

Shingen is sometimes referred to as "The Tiger of Kai" (甲斐の虎) for his martial prowess on the battlefield. His primary rival, Uesugi Kenshin (上杉謙信), was often called "The Dragon of Echigo" (越後の竜) or also "The Tiger of Echigo" (越後の虎).

"These two seemed to have enjoyed meeting in battle." They fought several times at Kawanakajima.

Early life

A modern reproduction of Takeda Shingen's famous armour

Takeda Shingen was the first-born son of Takeda Nobutora (武田信虎), leader of the Takeda clan, and daimyō of the province of Kai. He had been an accomplished poet in his youth. He assisted his father with the older relatives and vassals of the Takeda family, and became quite a valuable addition to the clan at a fairly young age. In 1536, at the age of 15, he was instrumental in helping his father win the Battle of Un no Kuchi.

At some point in his life after his "coming of age" ceremony, the young man decided to rebel against Nobutora. He finally succeeded in 1540, successfully taking control of the clan. Events regarding this change of leadership are not entirely clear, but it is thought that Nobutora had planned to name the second son, Nobushige, as his heir instead of Shingen. The end result was a miserable retirement that was forced upon him by Shingen and his supporters: he was sent to Suruga Province, on the southern border of Kai, to be kept in custody under the scrutiny of the Imagawa clan, led by his son-in-law Imagawa Yoshimoto (今川義元), the daimyō of Suruga. For their help in this bloodless coup, an alliance was formed between the Imagawa and the Takeda clans.

Initial expansion

Shinano Campaign

Shingen's first act was to gain a hold of the area around him. His goal was to conquer Shinano Province (信濃). A number of the major warlords in the Shinano region marched on the border of Kai Province, hoping to neutralize the power of the still-young Shingen before he had a chance to expand into their lands. However, planning to beat him down at Fuchu (where word had it Shingen was gathering his forces for a stand), they were unprepared when Takeda forces suddenly came down upon them at the Battle of Sezawa. Taking advantage of their confusion, Shingen was able to win a quick victory, which set the stage for his drive into Shinano lands that same year and his successful Siege of Uehara. The young warlord made considerable advances into the region, conquering the Suwa headquarters in the Siege of Kuwabara before moving into central Shinano with the defeat of both Tozawa Yorichika and Takato Yoritsugu in the Siege of Fukuyo and Battle of Ankokuji. In 1543, he captured Nagakubo castle, Kojinyama in 1544, and then Takatō and Ryūgasaki in 1545. In 1546 he took Uchiyama and won the Battle of Odaihara. In 1547, he took Shika. However, the warlord was checked at Uedahara by Murakami Yoshikiyo, losing two of his generals in a heated battle which Murakami won. Shingen managed to avenge this loss and the Murakami clan was eventually defeated in the Sieges of Toishi. Murakami fled the region, eventually coming to plead for help from the Province of Echigo (越後).

In 1548, Shingen defeated Ogasawara Nagatoki in the Battle of Shiojiritoge and then took Fukashi in 1550. In 1553, he captured Katsurao, Wada, Takashima and Fukuda. In 1554 he took Fukushima, Kannomine, Matsuo and Yoshioka.^:212–13

Conflict with Uesugi

After conquering Shinano, Shingen faced another rival, Uesugi Kenshin of Echigo. The feud between them became legendary, and they faced each other on the battlefield five times in the Battles of Kawanakajima.

These battles were generally confined to controlled skirmishes, neither daimyō willing to devote himself entirely to a single all-out attempt. The conflict between the two that had the fiercest fighting, and might have decided victory or defeat for one side or the other, was the fourth battle, during which the famous tale arose of Uesugi Kenshin's forces clearing a path through the Takeda troops and Kenshin engaging Shingen in single combat. The tale has Kenshin attacking Shingen with his sword while Shingen defends with his iron war fan or tessen. Both lords lost many men in this fight, and Shingen in particular lost two of his main generals, Yamamoto Kansuke and his younger brother Takeda Nobushige.^:269–72

After the fourth battle of Kawanakajima, the Takeda clan suffered two internal setbacks. Shingen uncovered two plots on his life, the first from his cousin Suwa Shigemasa (whom he ordered to commit seppuku), and the second, a few years later, from his own son Takeda Yoshinobu (武田義信). His son was confined to the Toko temple, where he died two years later; it is not known whether his death was natural or ordered by his father. After this incident, Shingen designated his fourth son, Takeda Katsuyori (武田勝頼), as the acting leader of the clan after himself until Katsuyori's son came of age.

In 1563, Shingen allied with Hōjō Ujiyasu, they captured Matsuyama Castle in Musashi Province. In 1565, Shingen then took Kuragano and Minowa Castle.

Suruga campaign

The death of Yoshinobu is believed to have much to do with the change in Shingen's Imagawa policy. After Imagawa Yoshimoto's death in a battle against Oda Nobunaga (織田信長) in 1560, Shingen had started to plan an invasion of Suruga, a territory now controlled by Yoshimoto's son Ujizane. Yoshinobu, however, had strongly opposed such a plan because his wife was the daughter of late Yoshimoto. By 1567, nonetheless, after Shingen had successfully kept the forces led by Uesugi Kenshin out of the northern boundaries of Shinano, taken over a strategically important castle in western Kōzuke, and suppressed internal objection to his plans to take advantage of the weakened Imagawa clan, he was ready to carry out his planned Suruga invasion. Shingen and Tokugawa Ieyasu (徳川康) "came to terms" and occupied the "former Imagawa territory."^:279 They both fought against Yoshimoto's heir, Imagawa Ujizane.

During this time Shingen also ordered the damming project of the Fuji River, which was one of the major domestic activities of the time.

Conflict with Hojo

In 1568, as a response to Hōjō's intervention in his invasion of Suruga Province, Shingen came into Musashi Province from his home province of Kai, attacking Takiyama castle. He then moved against the Hojo by attacking Hachigata Castle then engaged in the Siege of Odawara (1569). He burned Odawara castle then successfully withdrew after Hōjō Ujiteru and Hōjō Ujikuni failed to stop him in the Battle of Mimasetoge.^:216–18

After defeating the intervention forces commanded by Hōjō Ujimasa (北條氏政) of Sagami, Shingen finally secured the Suruga, formerly base of the prestigious Imagawa clan, as a Takeda asset in 1569.

Conflict with Oda-Tokugawa

Upon securing Takeda control over Suruga, northern Shinano, and western Kōzuke, Shingen moved to challenge the Oda-Tokugawa alliance in the Battle of Mikatagahara, this battle was one of the most famous battles of Takeda Shingen's campaigns, and one of the best demonstrations of his cavalry-based tactics. It was also one of Tokugawa Ieyasu's worst defeats, and complete disaster was only narrowly averted. After his victory Shingen lead a formidable force of over 30,000 into the latter's territories in Tōtōmi, Mikawa, and Mino in 1572.

Death

The exact circumstances surrounding Takeda Shingen's death are not known. There are many different stories, some of which are as follows.

When Takeda Shingen was 49 years old, he was the only daimyō with the necessary power and tactical skill to stop Oda Nobunaga's rush to rule Japan. He engaged Tokugawa Ieyasu's forces in 1572 and captured Futamata, and in January engaged in the Battle of Mikatagahara, where he defeated, but not decisively, a small combined army of Nobunaga and Ieyasu. After defeating Tokugawa Ieyasu, Shingen stopped his advance temporarily due to outside influences, which allowed the Tokugawa to prepare for battle again. He entered Mikawa Province, but soon died in the camp. Some accounts say he succumbed to an old war wound, some say a sniper wounded him earlier, and some accounts say he died of pneumonia. He was buried at Erin temple in what is now Kōshū, Yamanashi.

The film Kagemusha, by director Akira Kurosawa, loosely depicts a well-known version of his death in which a single sniper shot him at night. The other aspects of his death depicted in the film were artistic liberties taken by the director.

After death

Takeda Katsuyori became the daimyō of the Takeda clan. Katsuyori was ambitious and desired to continue the legacy of his father. He moved on to take Tokugawa forts. However an allied force of Tokugawa Ieyasu and Oda Nobunaga dealt a crushing blow to the Takeda in the Battle of Nagashino. Here Oda Nobunaga's matchlock-armed infantry destroyed the Takeda cavalry. Ieyasu seized the opportunity and defeated the weak Takeda led by Takeda Katsuyori in the battle of Tenmokuzan. Katsuyori committed suicide after the battle, and the Takeda clan never recovered.

Upon Shingen's death, Kenshin reportedly cried at the loss of one of his strongest and most deeply respected rivals. One of the most lasting tributes to Shingen's prowess was that of Tokugawa Ieyasu himself, who is known to have borrowed heavily from the old Takeda leader's governmental and military innovations after he had taken leadership of Kai during Toyotomi Hideyoshi's rise to power. Many of these designs were put to use in the Tokugawa shogunate.

While the Takeda were for the most part destroyed by the loss of Shingen's heir, Katsuyori, Shingen had a profound effect on the period in Japan. He influenced many lords with his law, tax, and administration systems, and many tales were told about him. Although aggressive towards military enemies he was probably not as cruel as other warlords. His war banner contained the famous phrase Fū-Rin-Ka-Zan (風林火山, "Wind, Forest, Fire, Mountain"), taken from Sun Tzu's The Art of War. This phrase refers to the idea of Swift as the Wind, Silent as a Forest, Fierce as Fire and Immovable as a Mountain. The motto applied to Shingen's policies and his military strategy.

Retainers

During the Edo period, 24 retainers who served under Shingen were chosen as a popular topic for ukiyo-e and bunraku. The names vary from work to work and the following list is the widely agreed version of retainers. They had not worked together, as some had died before others served, but they were noted for their exceptional contributions to Shingen and the Takeda family.

Takeda Shingen's 24 generals

Of his retainers, Kōsaka Masanobu stands out as being one of Shingen's better known beloveds, in the style of the Japanese shudō tradition. The two entered into the relationship when Shingen was 22 and Masanobu 16. The love pact signed by the two, in Tokyo University's Historical Archive, documents Shingen's pledge that he was not involved in, nor had any intentions of entering into, a sexual relationship with a certain other retainer, and asserts that "since I want to be intimate with you" he will in no way harm the boy, and calls upon the gods to be his guarantors.
