Eison

Eison (; courtesy name: Shien 思円; posthumous title: Kōshō Bosatsu 興正菩薩; 1201–1290) was a Japanese Buddhist monk active in the mid-Kamakura period. He founded the Shingon Risshu (Shingon Vinaya school). Eison was born in Mikata village, Soejō District, Yamato Province (present-day Yamatokōriyama, Nara), the son of the scholar-monk Keigen of Kōfuku-ji. He is regarded as one of the representative figures of Kamakura Buddhism, known for reviving the neglected Buddhist precepts and restoring the declining Saidai-ji in Nara.

Teachings and activities

Eison is remembered for reviving monastic precepts in Japan. He promoted devotion to Prince Shōtoku and Mañjuśrī, spread esoteric practices such as the Kōmyō Shingon, and engaged in extensive social work. He aided women, the poor, and those afflicted with leprosy. He was revered by all social classes, from outcasts to the imperial family and the Hōjō clan regents.

At age 60, he traveled to Kamakura, where he conferred precepts widely and reopened the ordination of nuns. Later, he was asked by the imperial court to assume leadership at Shitennō-ji due to his neutrality.

Eison also became associated with the origin of the Ōchamori tea rite, an oversized tea ceremony tradition of Saidai-ji. In 1281, during the Mongol invasion crisis, he conducted rituals invoking Aizen Myōō. Following Japan’s deliverance, he made a tea offering at the Hachiman Shrine using a giant tea bowl to serve the gathered crowds—an act that became the Saidai-ji Ōchamori rite.

While often celebrated for reviving the Vinaya, his true goal was reforming Shingon monasticism. He accepted certain privileges to support his charitable missions, which led to criticism from rivals such as Nichiren, who called him a “Vinaya traitor” (律国賊).

Legacy

Eison transmitted the Dharmaguptaka Vinaya (Shibunritsu), following Ganjin and Kakujō. His disciple Ninshō expanded the movement in eastern Japan with a strong emphasis on charity. At its height, Saidai-ji’s branch temples numbered over 1,500 nationwide.
