普明寺, A temple in Akishima City.

Fumyoji is a Tendai Buddhist temple in Haijimacho, Akishima, with the mountain name Haijimazan and Dainichi Nyorai as its principal image. It was founded as a subsidiary chapel of the neighbouring Dainichi-do, whose betto-ji it served, and was rebuilt during the Sengoku period. The temple stands at 1-20-16 Haijimacho, next to the Dainichi-do at 1-10-14.

Fumyoji's founding date is unknown; it was rebuilt during the Sengoku period. It began as a subsidiary hall of the neighbouring Dainichi-do, which it served as betto-ji, together with Honkaku-in (Haijima Daishi). In the Edo period the temple received a shuinjo as Dainichi-do territory.

The temple serves as a gathering place for the local community where people come together for ceremonies and festivals throughout the year. Visitors and residents alike use the space to offer prayers for health, safety, and personal goals, making this sanctuary an important part of neighborhood life.

The temple is about a 20-minute walk from the nearest train station along an easy path lined with trees and local houses. Parking is available for visitors arriving by car, and the grounds are open from early morning until evening any day of the week.

Fumyoji once served as the betto-ji, the administrative temple, of the neighbouring Dainido hall, and both stood together as a temple complex. The Dainido, a short walk away at 1-10-14 Haijimacho, holds four wooden statues designated Tokyo Metropolitan Cultural Properties: Dainichi Nyorai, Shaka Nyorai, Amida Nyorai and two Kongo Rikishi guardians.
