Hōkai-ji, Buddhist temple in Fushimi-ku, Kyoto, Japan

Hōkai-ji is a Shingon Daigo-school temple in Fushimi-ku, Kyoto, founded in 1051 by Fujiwara no Sukenari of the Hino line. Its Yakushi Hall, moved here in 1904 from the former Dentō-ji in Nara, dates to 1456 and enshrines a hidden Yakushi Nyorai statue. The Amida Hall, rebuilt after 1221, is a square hall with a surrounding open veranda and painted pillars.

The temple's origin is tied to Fujiwara no Sukenari (988–1070), founder of the Hino line, who in 1051 had a Yakushi Nyorai statue carved and placed a small image said to be carved by Saichō inside it, establishing a Yakushi hall. In 1221, soldiers ravaged the site, and it never regained its former scale; the Amida Hall was rebuilt soon after.

The temple is known as Hino Yakushi or Chichi Yakushi ("breast Yakushi") because the Yakushi Nyorai statue is believed to help with childbirth and nursing. Mothers from across Japan dedicate bibs (yodarekake) to the lattice doors of the Yakushi Hall, which are so numerous they obscure the interior. On 14 January the Hino no Hadaka Odori, a registered intangible folk cultural property, is performed on the hall's veranda.

The temple lies in Hino, Fushimi-ku, near the boundary with Uji. From Ishida Station on the Kyoto Municipal Subway Tozai Line it is about a 20-minute walk; alternatively, take Keihan Bus route 8 from Rokujizo Station to the Hino Yakushi stop. The halls stand close together, with the Yakushi Hall set slightly south of the Amida Hall.

The Yakushi Hall was moved here in 1904 from Dentō-ji, a temple in Tatsuta, Nara, that no longer exists. Its main Yakushi statue, 88 cm tall and carved from cherry wood, is unusual for its period. The hall's lattice doors are covered with bibs sent by mothers from across Japan.
