Kokutai-ji
Kokutai-ji, originally Tosho-ji, is one of fourteen autonomous branches of the Rinzai school of Japanese Zen, founded in 1300 by the monk Jiun Myoi in Toyama, Japan. In 1327 Emperor Go-Daigo gave the temple the name Kokutai-ji, and Jiun Myoi became Seisen Zenji.
Kokutai-ji was once also a temple of the Fuke sect, and housed komusō. Rinzai monks and priests still dress and practice suizen as komusō during memorial ceremonies in remembrance of Jiun Myoi.
