Musō Soseki
During the Muromachi period, the Rinzai school was the most successful of the schools because it was favoured by the "shōgun". The school may be said to have truly flowered and achieved a distinctly Japanese identity with Shūhō Myōchō (aka Daitō Kokushi 1283–1337) and Musō Soseki (1275–1351), two influential Japanese Zen masters who did not travel to China to study.
