The Founder
Iizasa Chōisai Ienao 飯篠 長威斉 家直
Chōisai-Sensei was born about 1387 during the Muromachi period.
The Founder was a prodigy in sword and spear techniques. He was undefeated in many battles, but in the end, the Chiba domain, which he served, was undone by internal and external conflict.
Disillusioned by these events, the Founder retreated to the shrine grounds of Katori Jingū. Here, he engaged in ritual austeries, sincere prayer, and arduous training. When he persevered for 1,000 days and nights, the Deity of Katori Jingū, Futsunushi no Kami, appeared to him as a young boy in an ancient plum tree and presented him with a scroll of divine martial techniques and strategy. Thus, the school he began is described as "Tenshin Shōden" – divinely and correctly transmitted.
Chōisai-Sensei passed away at the age of 102. He left a rich martial tradition and philosophy that we continue to this day.
