Water Spider Ninja Floatation Device

In this video I show the “mizugumo (water spider) from another school“ from the Bansenshukai, a book of ninjutsu compiled by Fujibayashi Yasutake in 1676. It’s called “from another school“ because Fujibayashi is referring to a school of ninjutsu other than his own. An english translation of the Bansenshukai is available in “The Book of Ninja“ by Antony Cummins and Yoshie Minami.
