Kokan Shiren

Kokan Shiren (虎関師錬), 1278–1347), Japanese Rinzai Zen patriarch and celebrated poet in Chinese, was the son of an officer of the palace guard and a mother of the aristocratic Minamoto clan. At age eight he was placed in the charge of the Buddhist priest Hōkaku on Mt. Hiei. At age ten he was ordained there, but later began study with the Zen master Kian at the Nanzenji monastery. Kokan Shiren’s talents came to the attention of the Emperor Kameyama. At age seventeen he began extensive Chinese studies. Thus began a long career of travel and the establishment of Zen institutions all across Japan. He became abbot at many of the best Zen establishments. At the end of his life, the emperor Gomurakami conferred upon him the title kokushi or National Teacher. Yet in his writings Kokan showed an aloofness from prestige with a striving for inner freedom. The best of his poetry in Chinese dates from late in his life when he had withdrawn from ecclesiastical affairs. His poetry and essays were collected under the title Saihokushū. He is also credited with other contributions to lexography in his lifetime.

Kokan compiled a thirty-chapter Buddhist history, the Genko Shakusho (元亨釈書), the oldest extant account of Buddhism in Japan. The work was completed in the Genko era, whence the era name in its title.

Kokan studied under the celebrated Chinese monk Yishan Yining. Their relationship can be regarded as the beginning of the golden age of the Literature of the Five Mountains in Japan. He studied calligraphy under an additional Chinese master Huang Shangu. Other works include Japan's first rhymed verse Jubun-in-ryaku in five volumes, Kokan Osho Juzenshiroku in three volumes, and the eighteen-volume Butsugo Shinron. A portrait of Kokan Shiren is in the Kaizoin of the Tōfuku-ji Temple in Kyoto, Japan.

Of great interest for the development of the Japanese garden, bonseki, bonsai and related arts is Kokan Shirens rhymeprose essay Rhymeprose on a Miniature Landscape Garden. Obvious influence can be seen from Chinese Song period literati. Kokan Shiren’s deceptively simple and straightforward narration gave and early voice to what would become a profound cultural transformation in Japan:
