Keisei (1189âÂÂ1268) was a Japanese Buddhist priest of the Tendai sect. He was a son of the regent Kujà  Yoshitsune of the Fujiwara clan. His spine was permanently injured in infancy when he was dropped by his wet nurse, which probably influenced his decision to become a priest. He studied under the monk Myà Âe and then established a hermitage west of Kyà Âto. In 1217, he travelled to China, where he stayed about a year before returning to Japan. In China, he commissioned a nanban ("southern barbarian", i.e., a Persian) to write an inscription in Persian for Myà Âe.
In 1222, Keisei composed a collection of setsuwa entitled Kankyo no Tomo (Companion of a Quiet Life, or Companion in Solitude). It was formerly attributed to Jien. To Keisei has also been attributed the Hyà Âtà  Ryà «kyà « no kuni no ki, an account of a voyage to the Ryà «kyà « Kingdom in 1244.
