The Takeda clan was a prominent samurai family in Japan during the late Heian period and the Sengoku period. They were known for their military prowess and strategic acumen, particularly under the leadership of Takeda Shingen, one of the most famous warlords of the time. The clan's territory was primarily in the Kai Province, which is now part of Yamanashi Prefecture. The Takeda clan engaged in numerous battles against rival clans, including the Uesugi clan and the Oda clan. Their signature tactics included the use of cavalry and innovative battlefield strategies. Despite their strength, the clan eventually declined after the death of Takeda Shingen in 1573, leading to their eventual defeat by the forces of Tokugawa Ieyasu.
