The Shingen-kō Festival (信玄公祭り, Shingen-ko Matsuri) is a Japanese festival (matsuri) which is held annually to celebrate the legacy of daimyō Takeda Shingen in Kōfu, the capital city of Yamanashi Prefecture.

[1][2] Takeda Shingen (武田 信玄, 1 December 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.

After the Shingen-ko Tea Ceremony, Takeda leads his army through the streets of Kōfu.

These parades are very theatrical involving serious reenactments who practice the rest of the year for this one weekend in April.

Seeing so many people in traditional costumes and more than 1000 samurai gives an impression of what the Sengoku Period was like (1467 – 1600 CE).

Exchange students of the University of Yamanashi are usually the guard samurai group of the princess.

Part of the proceeds went to support the area affected by the 2011 Tōhoku earthquake and tsunami.
