Ichikawamonjo
Period: Late Heian – Late Sengoku period (12C- 16C)
The Ichikawa Family Document is a representative samurai document of Shinano Province (now Nagano Prefecture). It was bequeathed to the Ichikawa clan, who ruled Oku-Shinano (the present-day northern part of Nagano’s Shimotakai district) for 400 years from the end of the Heian period to the end of the Sengoku period. It contains the only surviving document on Kiso Yoshinaka, news from Hojo Yoshitoki, and a letter from Takeda Shingen, and as such, constitutes one of the most valuable samurai documents to be found anywhere in Japan.
