Jakuen

After Rujing's death in 1228, Jakuen immigrated to Japan in order to join his friend's emerging Sōtō school, but did not receive dharma transmission from Dōgen directly, rather his disciple Koun Ejō.

He arrived on a remote mountain in Fukui prefecture, where he became famous to the locals for his ascetic meditation on a mountainside without the benefit of any monastic community.

During this time, according to medieval legend, he gained the friendship of a cow and dog who would follow him into town during almsrounds.

Eventually he built a monastery called Hōkyō-ji (宝慶寺) in the style of Tiāntóng, which today owns the only surviving early treasures of Eihei-ji, and serves as a training center for Japanese and international Sōtō Zen Buddhists.

In medieval Japan Jakuen's monastic community split into two separate lineages, one at Hōkyō-ji and one at Eihei-ji which was responsible for some of the corruption that went on there.
