Seppuku'cutting [the] belly', also called hara-kiri (腹切り, abdomen/belly cutting, a native Japanese kun reading), is a form of Japanese ritualistic suicide by disembowelment. While harakiri refers to the act of disemboweling oneself, seppuku refers to the ritual and usually would involve decapitation after the act as a sign of mercy. Harakiri refers solely to the act of disembowelment and would only be assigned as a punishment towards acts deemed too heinous for seppuku.
AshigaruAshigaru were infantry employed by the samurai class of feudal Japan. The first known reference to ashigaru was in the 14th century, but it was during the Ashikaga shogunate (Muromachi period) that the use of ashigaru became prevalent by various warring factions. Attempts were made in Japan by Emperor Tenmu (673–686) to have a conscripted national army, but this did not come about, and by the 10th century Japan instead relied on individual landowners to provide men for conflicts and wars.
Sankin-kōtaiSankin-kōtai (参覲交代/参覲交替, now commonly written as 参勤交代/参勤交替) was a policy of the Tokugawa shogunate during most of the Edo period of Japanese history. The purpose was to strengthen central control over the daimyōs (major feudal lords). It required feudal lords, daimyō, to alternate living for a year in their domain and in Edo, the capital. Toyotomi Hideyoshi had earlier established a similar practice of requiring his feudal lords to keep their wives and heirs at Osaka Castle or the nearby vicinity as hostages to ensure their loyalty.
Tokugawa IeyasuTokugawa Ieyasu was the founder and first shōgun of the Tokugawa Shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was one of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as a vassal and general of the Oda clan, and building up his strength under Oda Nobunaga.
Toyotomi HideyoshiToyotomi Hideyoshi, otherwise known as Kinoshita Tōkichirō and Hashiba Hideyoshi, was a Japanese samurai and daimyō (feudal lord) of the late Sengoku period regarded as the second "Great Unifier" of Japan. Hideyoshi rose from a peasant background as a retainer of the prominent lord Oda Nobunaga to become one of the most powerful men in Japan. Hideyoshi succeeded Nobunaga after the Honnō-ji Incident in 1582 and continued Nobunaga's campaign to unite Japan that led to the closing of the Sengoku period.
Tokugawa shogunateThe Tokugawa shogunate (ˌtɒkuːˈgɑːwə ; Tokugawa bakufu, tokɯŋawa baꜜkɯ̥ɸɯ), also known as the Edo shogunate, was the military government of Japan during the Edo period from 1603 to 1868. The Tokugawa shogunate was established by Tokugawa Ieyasu after victory at the Battle of Sekigahara, ending the civil wars of the Sengoku period following the collapse of the Ashikaga shogunate. Ieyasu became the shōgun, and the Tokugawa clan governed Japan from Edo Castle in the eastern city of Edo (Tokyo) along with the daimyō lords of the samurai class.
Ashikaga shogunateThe Ashikaga shogunate, also known as the Muromachi shogunate, was the feudal military government of Japan during the Muromachi period from 1336 to 1573. The Ashikaga shogunate was established when Ashikaga Takauji was appointed Shōgun after overthrowing the Kenmu Restoration shortly after having overthrown the Kamakura shogunate in support of Emperor Go-Daigo. The Ashikaga clan governed Japan from the Imperial capital of Heian-kyō (Kyoto) as de facto military dictators along with the daimyō lords of the samurai class.
Oda NobunagaOda Nobunaga was a Japanese daimyō and one of the leading figures of the Sengoku period. He is regarded as the first Tenka-bito of Japan. Nobunaga was an influential figure in Japanese history and is regarded as one of the three great unifiers of Japan, along with his retainers Toyotomi Hideyoshi and Tokugawa Ieyasu. Hideyoshi later united Japan in 1591 and invaded Korea a year later. However, he died in 1598, and Ieyasu took power after the Battle of Sekigahara in 1600, becoming shogun in 1603, and ending the Sengoku period.
EdoEdo (), also romanized as Jedo, Yedo or Yeddo, is the former name of Tokyo. Edo, formerly a jōkamachi (castle town) centered on Edo Castle located in Musashi Province, became the de facto capital of Japan from 1603 as the seat of the Tokugawa shogunate. Edo grew to become one of the largest cities in the world under the Tokugawa. After the Meiji Restoration in 1868 the Meiji government renamed Edo as Tokyo (, "Eastern Capital") and relocated the Emperor from the historic capital of Kyoto to the city.
Edo societyEdo society refers to the society of Japan under the rule of the Tokugawa Shogunate during the Edo period from 1603 to 1868. Edo society was a feudal society with strict social stratification, customs, and regulations intended to promote political stability. Japanese people were assigned into a hierarchy of social classes based on the Four Occupations that were hereditary. The Emperor of Japan and the kuge were the official ruling class of Japan but had no power.
