Tōmyō-ji, Buddhist temple in Hirai, Japan.

Tōmyō-ji is a Buddhist temple in Edogawa, Tokyo, centered around a large main hall dedicated to the deity Fudo Myooh. A separate Shotendo building houses another Buddhist figure and contributes to the layered design of the complex.

Tōmyō-ji was founded by the monk Genkyō, though the exact date is unknown. In 1749 the monk Eyu, who died that year, revived the temple and enshrined a Shōten deity, making it a center of Shōten worship. It once belonged to the Shingon Buzan school and was reorganized into the Shingi Shingon school after World War II, with Kanren-in as its former head temple.

The temple is known as Hirai Shōten, one of the Kantō Three Shōten alongside Menuma Shōten in Saitama and Matsuchiyama Shōten in Asakusa. The Shōten hall, honoured as an Edogawa City historic site in 1982, has drawn worshippers for centuries.

The site is a short three-minute walk from Hirai Station on the JR Sobu Line, offering easy access from around central Tokyo. The convenient location makes it straightforward to include in a day of exploring the area.

A chandelier sold off when Tokyo's Rokumeikan hall was demolished is kept at the temple. The hall, designed by Josiah Conder and opened in 1883 for Western-style social functions, was taken down in 1940; its fittings were dispersed, and this one ended up in Hirai.
