Ishinomori Shoutarou no Rekishi Adventure

A two-part production features Dr. Teng, a researcher from the Time Institute, and his kappa assistant Pasuke as they journey through different historical battles in Japan. The first part covers the Battle of Sekigahara in 1600 and the fourth Battle of Kawanakajima in 1561. The second part explores the final stand of Yoshitsune in 1189 before moving forward in time to 1575, when Nobunaga Oda first used firearms at the Battle of Nagashino. The series blends live-action and animation and is described as a documentary with narrative elements. It is likely connected to Shotaro Ishinomori's multi-volume manga on Japanese history.
