Hōzen-ji, Buddhist temple in Minami-Alps, Japan

Hōzen-ji is a Shingon Buddhist temple in the Kagami district of Minami-Alps, Yamanashi, with the mountain name Kagami-san. Its main image is Amida Nyōrai, and it served as the bettō temple of Takeda Hachiman-gū. The grounds preserve a Muromachi-period bell tower and a bronze bell; the temple's buildings were lost to fire in 1781.

The temple traces its origin to Eizen-ji, founded in 802 in present-day Hokuto and re-established by Kūkai in 822. In 1208 it was moved to its current site by Tōtsune, grandson of Kagami Tomomitsu, and became the bettō temple of Takeda Hachiman-gū. After the Takeda clan fell, Toyotomi Hideyoshi and Tokugawa Ieyasu protected it; in 1642 Tokugawa Iemitsu confirmed its lands, then nine subsidiary temples and twenty chapels. A 1781 fire destroyed the halls.

The temple's name is written 法善寺, and its mountain name, Kagami-san, ties it to the Kagami family from whom the Takeda clan descended. As bettō temple of Takeda Hachiman-gū, it received that shrine's sutras and mirror image of Amida when Shinto and Buddhism were separated in the early Meiji period. The 1254 Mahaprajnaparamita Sutra, donated by Ichijō Nobunaga, is kept in six lacquered boxes.

The temple stands in the Kagami district of Minami-Alps, Yamanashi, at the foot of the mountains, with the grounds laid out around the main hall and bell tower. The bell tower and the bronze bell it shelters are both Yamanashi Prefectural Cultural Properties, so look for them on the grounds. The temple is the bettō temple of Takeda Hachiman-gū in nearby Nirasaki, and the shrine's former treasures, including the Dai-Hannyakyō sutra, are kept here.

The temple's best-known object is a Fudō Myō-ō statue said to have survived the wartime bombing of the area, after which it became the temple's main attraction. The temple also keeps a Kamakura-period copy of the Dai-Hannyakyō sutra: 561 of 600 volumes, donated in 1254 by Ichijō Nobunaga to Takeda Hachiman-gū and transferred here in the early Meiji period.
