立源寺, Buddhist temple in Meguro district, Japan.

Ryigenji is a Buddhist temple in Tokyo with multiple buildings including the Niomon Gate, the Dai-Hondo main hall, the Shorodo bell tower, and the Amidado hall set on elevated grounds. The temple grounds are carefully arranged and offer various religious spaces for worship and ceremonies.

Founded in 1624 by Nisshun, Ryugenji was one of the temples of the Nichiren-shu Fuju-fuse-ha, which refused offerings from non-believers and gave none to them. In 1698, when Fudanaka Hokke-ji (now Enyu-ji) converted to Tendai-shu, Ryugenji became a branch temple of Minobu-san Kuon-ji.

The temple belongs to the Nichiren school and is known as Bumon-dani Sanpo-den. Its main image is the Three Treasures, a statue bearing the inscription of Hokke-ji and the signature of Nichiharu, the temple's 13th abbot, showing it was moved here from Hokke-ji. Two wooden statues of Monju and Fugen Bosatsu date from 1845.

You can reach the temple with a 10-minute walk from Fudo-mae Station on the Tokyo Meguro Line. The 28th of each month features special festivals and events at the temple.
