The Rinzai school ,named after Linji Yixuan is one of three sects of Zen in Japanese Buddhism, along with Sōtō and Ōbaku. The Chinese Linji school of Chan Buddhism was first transmitted to Japan by Myōan Eisai. Contemporary Japanese Rinzai is derived entirely from the Ōtōkan lineage transmitted through Hakuin Ekaku (1686–1769), who is a major figure in the revival of the Rinzai tradition.

Zen is a school of Mahayana Buddhism that originated in China during the Tang dynasty as the Chan School or the Buddha-mind school, and later developed into various sub-schools and branches. From China, Chán spread south to Vietnam and became Vietnamese Thiền, northeast to Korea to become Seon Buddhism, and east to Japan, becoming Japanese Zen.
