Ōbaku
Ōbaku Zen or the Ōbaku school (Japanese: 黄檗宗, romanized: Ōbaku-shū) is one of three main schools of Japanese Zen Buddhism, in addition to the Sōtō and Rinzai schools. The school was founded in Japan by the Chinese monk Ingen Ryūki, who immigrated to Japan during the Manchu conquest of China in the 17th century.
