Shōsan trained under a Zen master we know little about, Daigu Sochiku, who allowed Shōsan to keep his original name. Shōsan never actually received "inka" but was one of many in the Tokugawa period to claim "jigo-jishō" or "self-enlightenment without a teacher". He was a Zen Master who amassed a large following. In 1642, Shōsan, along with his brother, built 32 Buddhist temples in Japan. One was a Pure Land Buddhist temple in which he honoured the "shōguns" Tokugawa Ieyasu and Tokugawa Hidetada. Shōsan went on to write several treatises before his death in 1655 at 76 years old.
