Iizasa Ienao

Iizasa Chōisai Ienao (飯篠 長威斉 家直) was the founder of Tenshin Shōden Katori Shintō-ryū which is a traditional (koryū) Japanese martial art. His Buddhist posthumous name is Taiganin-den-Taira-no-Ason-Iga-no-Kami-Raiodo-Hon-Daikoji.

He was a respected spearman and swordsman who served the Chiba family in what is today Chiba Prefecture. When his home town was destroyed he began wandering the land until he settled down near the Katori Shrine and founded the Tenshin Shōden Katori Shintō-ryū in c.1447.
