Kogenji, Buddhist temple in Tokushima, Japan.

Kogenji is a Buddhist temple in Tokushima with a main hall dating to the early 1800s, displaying traditional Japanese architectural style and religious objects. The grounds contain several buildings arranged around a central area, surrounded by mature trees and stone pathways.

The temple began as Fuku-ji, founded inside Tokushima Castle by Tōgaku, a Rinzai monk and half-brother of Hachisuka Iemasa. In 1586 Iemasa moved it to Shimojosumachi, and in 1636 the second lord Tadateru renamed it Kōgenji, mountain name Daiōzan. The Hachisuka family tombs stand in a walled enclosure beside the grounds, and the temple once received 550 koku in stipend.

Kogenji is the family temple of the Hachisuka lords of Tokushima Domain and held 550 koku of temple revenue in the domain era. The Kogenji River flows through the grounds. The Hachisuka cemetery, a nationally designated Historic Site, lies behind a mud wall; the graves of founder Masakatsu and his wife Matsu stand apart from the successive lords' tombs.

The temple is reached by a ten-minute walk from the Kokubunji-mae bus stop, which has direct connections to Tokushima Station. It is best visited in the morning when the grounds are quieter and you can move around freely.

The temple grounds hold the graves of the Hachisuka lords, and the tombs of the family founder Hachisuka Masakatsu and his wife Matsu stand apart from those of the later lords. The temple also keeps the graves of the Edo-period physician Inoue Fumei and the army major general Watanabe Hiroshi.
