Honryū-ji, Buddhist temple in Kamigyō-ku, Japan

Honryū-ji is the head temple of the Shingon-ryū branch of the Hokke sect in Kamigyō-ku, Kyoto. Its main hall, rebuilt in 1657 by the master carpenter Sakanoue Sakushō-no-jō Yoshisada, is an irimoya-zukuri structure with tiled roof and the oldest main hall among the sixteen Hokke temples in Kyoto. The founder's hall, built around the same year, has a coffered ceiling with over 150 mirror panels painted with plants on an ultramarine background.

Founded in 1488 by Nichishin, a disciple of Myōhon-ji's Nichigu, the temple first stood at Shijō Ōmiya. Its halls burned in the 1536 Tenbun Hokke War and it fled to Sakai; in 1542 it returned to Kyoto and was rebuilt on its present site. The main hall and founder's hall, rebuilt in 1657, survived the 1788 Tenmei fire, earning the name "Yakezu no tera" (unburned temple).

Honryū-ji belongs to the Hokke-shū Shinmon-ryū school, whose head temple it is, and its name is written with the characters for "origin" and "prosperity". The temple keeps the Mōkō-ji line founded by Nichishin, and its grounds hold a pine believed to stop infants from crying at night: walking around it, or placing its leaves and bark under a child's pillow, is said to cure the crying.

Honryū-ji stands at 330 Monya-chō, Chieikōin Gojō-agaru, Kamigyō-ku. It is about 15 minutes on foot from Imadegawa subway station, or 5 minutes from the Imadegawa-Ōmiya city bus stop. The main hall and founder's hall, both from 1657, face the grounds entered through the south gate.

The temple's nickname, "Yakezu no tera" (the unburned temple), comes from the 1788 Tenmei fire, which left the surrounding Nishijin district in ashes while the main hall, founder's hall and treasure storehouse survived. The main hall, rebuilt in 1657 by the carpenter Sakanoue Sakasuke-no-jō Yoshisada, is the oldest of the 16 Hokke-shū head temples in Kyoto.
