Shin'ichi Hisamatsu (久松 真一, Hisamatsu Shin'ichi, June 5, 1889 – February 27, 1980) was a philosopher, Zen Buddhist scholar, and Japanese tea ceremony (sadō or chadō, 茶道, "the way of tea") master.
He entered Kyoto University in 1912 and studied philosophy with Kitarō Nishida, one of the most prominent Japanese philosophers of his time and the author of An Inquiry into the Good.
After his monastic life at Myōshin-ji, he established his original philosophical view, which consists of both Eastern (mainly Zen Buddhist) and Western philosophy.
[3] The FAS Society’s origin, Gakudō Dōjō, was established by students of Kyoto University under Hisamatsu's guidance.
In the Netherlands and Belgium the message of Hisamatsu is kept alive by Zen teacher Ton Lathouwers.
