Zenrin Temple, Buddhist temple in Mitaka, Japan

Zenrin Temple is an Obaku Zen temple in Mitaka, Tokyo, with the mountain name Reisen-zan. Its grounds contain a Benzaiten hall, a thirteen-story pagoda built to mourn victims of the Great Fire of Meireki, and a memorial tower for victims of the Mitaka Incident. The cemetery holds the graves of Mori Ogai and Osamu Dazai, which face each other.

Zenrin Temple was founded in the early Edo period as a Jodo Shinshu temple by residents of Kanda Renjaku-cho who were relocated after the Great Fire of Meireki. In 1770 (Meiwa 7) a typhoon destroyed it, and the Obaku monk Kenzhou Genyo rebuilt it, renaming it Zenrin-ji.

Mori Ogai's grave was moved here after the temple that held it burned, and Dazai Osamu, who admired him, asked to be buried opposite. Dazai's birthday, 19 June, brings the annual Otoran-ki memorial, while Ogai's service on 9 July is held after the cherry blossoms on Dazai's grave have faded; Ogai's admirers then lay fresh flowers on Dazai's grave too.

Zenrin Temple is about a 10-minute walk from the south side of Mitaka Station on the JR Chuo Main Line. The temple grounds lie roughly in the centre of Mitaka, south of the station, and the walk continues through land the temple still owns northward to the station's north side.

The graves of Osamu Dazai and Mori Ogai face each other here. Dazai, who admired Ogai, asked to be buried opposite him, and when the temple agreed, parishioners strongly opposed the plan until the abbot persuaded them. Dazai's wife, Michiko Tsushima, lies beside her husband.
