Ninpiden
1560 ninjutsu manual by Hattori Hanzō
From Wikipedia, the free encyclopedia
The Ninpiden (a.k.a. Shinobi Hiden, or Legends of Ninja Secrets) is an authentic ninjutsu manual written by Hattori Hanzō in 1560.[1] It is regarded as one of the three key historical texts of ninjutsu, along with the Shōninki and the Bansenshukai.[2][3] It was passed down in the Hattori family, and was considered a secret transmission; it was not shared with outsiders and even within the family, few had access to it.[4]
