Tempu Nakamura

His father introduced the use of paper money in Japan when he served as the bureau director of the Japanese Ministry of Finance.

He left the school and joined Gen'yōsha ultra-nationalist secret society, forming a friendship with Tōyama Mitsuru.

He was one of only nine out of 113 military affairs investigators to return to Japan alive from the Russo-Japanese War, after which he suffered a severe attack of tuberculosis at the age of 30.

Seeking a cure for the illness, he studied the autonomic nerves at Columbia University, and traveled to England, Germany, Belgium and France.

Tempu-Kai is headquartered in Otsuka (大塚), Bunkyo-ku, Tokyo, and actively holds seminars and retreats to teach his Shinshin-tōitsu-dō.

They include: Tōgō Heihachirō, Hara Takashi, Seibo Kitamura, Chiyo Uno, Futabayama Sadaji, Tatsuro Hirooka, Konosuke Matsushita, Kazuo Inamori, et al.,[4] and more recently, Shohei Ohtani.
