Japanese Zen is derived from the Japanese pronunciation of the Middle Chinese word 禪 (Chan) which traces its roots to the Indian practice of dhyāna ("meditation"). Buddhism was introduced to China in the first century CE. According to tradition, Chan was introduced around 500 CE by Bodhidharma, an Indian monk teaching dhyāna.

Zen was not introduced as a separate school in Japan until the 12th century during the Kamakura
