Shinjitai : 関ヶ原の戦い;Kyūjitai : 關ヶ原の戰ひ|Sekigahara no Tatakai, popularly known as the nihongo|Realm Divide|天下分け目の戦い|Tenka Wakeme no Tatakai, was a decisive battle onOctober 21 ,1600 ("Keichō 5, 15th day of the 9th month") which cleared the path to theShogun ate forTokugawa Ieyasu . Though it would take three more years for Ieyasu to consolidate his position of power over theToyotomi clan and thedaimyo , Sekigahara is widely considered to be the unofficial beginning of the Tokugawa bakufu, the lastshogun ate to controlJapan .Background and pretext
Even though
Toyotomi Hideyoshi unified Japan and consolidated his power following the Siege of Odawara in 1590, his ill-fated invasion of Korea significantly weakened the Toyotomi clan's power as well as the loyalists and bureaucrats that continued to serve and support the Toyotomi clan after Hideyoshi's death. Hideyoshi's and his brother Hidenaga's presence kept the two sides from anything more than quarreling, but when both of them died, the conflicts were exacerbated and developed into open hostilities. Since the Toyotomi clan was known to be descended from peasant stock, neither Hideyoshi nor his heir Hideyori would be recognized or accepted asShogun . Most notably,Kato Kiyomasa andFukushima Masanori were publicly critical of the bureaucrats, especiallyIshida Mitsunari andKonishi Yukinaga . Tokugawa Ieyasu took advantage of this situation, and recruited them, redirecting the animosity to weaken the Toyotomi clan.Beginning
Tokugawa Ieyasu was no longer rivaled in terms of seniority, rank, reputation and overall influence within the Toyotomi clan after the death of Regent
Maeda Toshiie . Rumors started to spread stating that Ieyasu, at that point the only surviving ally ofOda Nobunaga , would take over Hideyoshi's legacy just as Nobunaga's was taken. This was especially evident amongst the loyalist bureaucrats, who suspected Ieyasu of agitating unrest amongst Toyotomi's former vassals.Later, a supposed conspiracy to assassinate Ieyasu surfaced, and many Toyotomi loyalists, including Toshiie's son, Toshinaga, were accused of taking part and forced to submit to Ieyasu's authority. However,
Uesugi Kagekatsu , one of Hideyoshi's appointed regents, defied Ieyasu by building up his military. When Ieyasu officially condemned him and demanded that he come toKyoto to explain himself before the emperor, Kagekatsu's chief advisor,Naoe Kanetsugu responded with a counter-condemnation that mocked Ieyasu's abuses and violations of Hideyoshi's rules, in such a way that Ieyasu was infuriated.Afterwards, Ieyasu summoned the help of various supporters and led them northward to attack the Uesugi clan, which at that moment were besieging Hasedō, but
Ishida Mitsunari , grasping the opportunity, rose up in response and created an alliance to challenge Ieyasu's supporters, also seizing variousdaimyo as hostages inOsaka Castle . Ieyasu then left some forces led byDate Masamune to keep the Uesugi in check and marched west to confront the western forces. A few daimyo, most notablySanada Masayuki , left Ieyasu's alliance, although most, either bearing grudges against Mitsunari or being loyal to Ieyasu, stayed with him.The battle
Mitsunari, in his home
Sawayama Castle , met withOtani Yoshitsugu ,Mashita Nagamori , andAnkokuji Ekei . Here, they forged the alliance, and invited Mori Terumoto, who actually did not take part in the battle, to be its head.Mitsunari then officially declared war on Ieyasu and lay siege to the
Fushimi Castle , garrisoned by Tokugawa retainerTorii Mototada onJuly 19 . Afterwards, the western forces captured various Tokugawa outposts in theKansai region and within a month, the western forces had moved into theMino Province , where Sekigahara was located.Back in
Edo , Ieyasu received news of the situation in Kansai and decided to deploy his forces. He had some former Toyotomi daimyo engage with the western forces while he split his troops and marched west on the Tōkaidō towardsOsaka Castle . Ieyasu's son Hidetada led another group throughNakasendō . However, Hidetada's forces were bogged down as he attempted to besiegeSanada Masayuki 's Ueda Castle. Even though the Tokugawa forces numbered some 38,000, an overwhelming advantage over the Sanada's mere 2,000, they were still unable to capture the strategist's well-defended position. At the same time, 15,000 Toyotomi troops were being held up by 500 troops under Hosokawa Fujitaka at Tanabe Castle in Wakayama Prefecture. Some among the 15,000 troops respected Hosokawa so much they intentionally slowed their pace down. Both these incidents resulted in a large number of Tokugawa and Toyotomi troops not to show up in time at the battlefield of Sekigahara.Knowing that Ieyasu was heading toward Osaka, Mitsunari decided to abandon his positions and marched to Sekigahara. On September 15, 1600 ("
Keichō 5, 8th day of the 8th month"), the two sides started to deploy their forces. Ieyasu's eastern army had 88,888 men, whilst Mitsunari's western army numbered 81,890. There were about 20,000 arquebusers and other forms of hand-held gunners deployed in the battlefield, corresponding to over 10% of all troops present.Fall of the western army
Even though the western forces had tremendous tactical advantages, Ieyasu had already contacted many daimyo on the western side, promising them land and leniency after the battle should they switch sides. This led some western commanders holding key positions to hesitate when pressed to send in reinforcements or join the battle that was already in progress.
Mori Hidemoto and Kobayakawa Hideaki were two such daimyo. They were in such positions that if they decided to close in on the eastern forces, they would in fact have Ieyasu surrounded on three sides. Hidemoto, shaken by Ieyasu's promises, also persuaded Kikkawa Hiroie not to take part in the battle.
Even though Kobayakawa had responded to Ieyasu's call, he remained hesitant and neutral. As the battle grew more intense, Ieyasu finally ordered
arquebus iers to fire at Kobayakawa's position onMount Matsuo . At that point Kobayakawa joined the battle on the eastern side. His forces assaulted Yoshitsugu's position, which quickly fell apart as he was already engagingTodo Takatora 's forces. Seeing this as an act of treachery, western generals such asWakisaka Yasuharu ,Ogawa Suketada ,Akaza Naoyasu , andKutsuki Mototsuna immediately switched sides, turning the tide of battle.The western forces disintegrated afterwards, and the commanders scattered and fled. Some, like
Ukita Hideie managed to escape, while others, like Sakon was shot and wounded by a rifle though it's unknown if he died from it, Otani Yoshitsugu committed suicide. Mitsunari, Yukinaga and Ekei were some of those who were captured and a few, like Mori Terumto and Shimazu Yoshihiro were able to return to their home provinces. Mitsunari himself would be decapitated.Rise of the Tokugawa Shogunate
Tokugawa Ieyasu redistributed the lands and fiefs of the participants, generally rewarding those who assisted him and displacing, punishing, or exiling those who fought against him. In doing so, he gained control of many former Toyotomi territories. Following the public execution of
Ishida Mitsunari ,Konishi Yukinaga andAnkokuji Ekei , the influence and reputation of the Toyotomi clan and its remaining loyalists drastically decreased.From the Toyotomi clan's point of view though, the battle was technically only an internal conflict between Toyotomi vassals.
This view was challenged however because Ieyasu was later made
Shogun , a position that had been left vacant since the fall of theAshikaga shogunate 27 years earlier. In 1664, Tokugawa historian andYushima Seido rectorHayashi Gahō , writing in 1664, summarized the consequences of the battle: "Evil-doers and bandits were vanquished and the entire realm submitted to Lord Ieyasu, praising the establishment of peace and extolling his martial virtue. That this glorious era that he founded may continue for ten thousands upon ten thousands of generations, coeval with heaven and earth." [Hoffman, Michael. [http://search.japantimes.co.jp/cgi-bin/fl20060910x2.html "A man in the soul of Japan"] , "Japan Times" (Tokyo). September 10, 2006.]This change in official rankings also reversed the subordinate position of the Tokugawa clan, thus making the Toyotomi clan subordinates of the Tokugawa instead. In any case, Ieyasu did not gain any
casus belli to take action against the frail Toyotomi clan; rather, it would take more political maneuvers for Ieyasu to destroy Hideyori once and for all.eeds of Dissent
While most clans were content with their new status, there were many clans, especially those on the western side, who became bitter about their displacement or what they saw as a dishonorable defeat or punishment. Three clans in particular did not take the aftermath of Sekigahara lightly:
*The
Mōri clan , headed byMori Terumoto , remained angry toward theTokugawa shogunate for being displaced from their fief, Aki, and being relocated to theChōshū Domain , even though the clan did not take part in the battle at all.*The
Shimazu clan , headed byShimazu Yoshihiro , blamed the defeat on its poor intelligence-gathering, and while they were not displaced from their home province of Satsuma, they did not become completely loyal to the Tokugawa shogunate either. Taking advantage of its large distance between Edo and the island of Kyushu as well as its improved espionage, the Shimazu clan demonstrated that it was virtually an autonomous kingdom independent from the Tokugawa shogunate during its last days.*The
Chosokabe clan , headed byChosokabe Motochika , was stripped of its title and domain of Tosa and sent into exile. Former Chosokabe retainers never quite came to terms with the new ruling family, theYamauchi clan , which made a distinction between its own retainers and former Chosokabe retainers, giving them lesser status as well as discriminating treatment. This class distinction continued even generations after the fall of the Chosokabe clan.The descendants of these three clans would in two centuries collaborate to bring down the Tokugawa shogunate, leading to the
Meiji Restoration .Miyamoto Musashi
*According to tradition, the legendary
kensei Miyamoto Musashi was present at the battle among the ranks of Ukita Hideie's army. Supposedly, he fought well and escaped the defeat of Hideie's forces unharmed. Whether this is fact or myth is unknown; Musashi would have been around 16 years of age at the time.Appearances in popular culture
