Rakan-ji (Go-hyaku Rakan) is a temple of the Koyasan Shingon sect located in Oda City, Shimane Prefecture. It is registered as part of the UNESCO World Heritage site, "Iwami Silver Mine and its Cultural Landscape," and serves as a precious religious site showcasing the stone masonry techniques of the Iwami Silver Mine era. The most striking feature is the collection of 501 stone Rakan seated statues enshrined within three stone caves carved into the natural rock slope. The central cave houses the Shakyamuni Buddha triad, while the left and right caves each contain 250 Rakan statues, creating a profound spiritual atmosphere.
The temple was founded in 1764 by Gekkai Join. However, the creation of the Go-hyaku Rakan dates back even earlier to the Genbun era (1736–1740). The project was inspired when an official from the Omori Magistrate's Office visited Kanon-ji and witnessed the stone Sixteen Rakan statues. With the cooperation of local officials and residents, the construction took approximately 25 years to complete. The statues were carved by the school of Tsubouchi Heishichi, renowned stone masons from Yunotsu. The site holds deep historical significance, as it was built alongside stone bridges and monuments to offer prayers for the souls of those who perished in the silver mines and for the ancestors of the region.

The three stone caves carved into the rock face are the primary attraction. In the central cave, the Shakyamuni Buddha triad is enshrined, surrounded by a total of 501 Rakan statues distributed across the side caves. These figures are a testament to the advanced stone-carving skills of the period. Visitors can also observe historical stone structures within the grounds, such as the arched stone bridge built during the temple's founding and various stone pagodas (Hokyo-intō). Additionally, do not miss the legendary "Twin Dragons" painted on the ceiling of the main hall.
Rakan-ji offers a beautiful historical landscape regardless of the season. To fully appreciate the intricate details of the Buddhist statues and the stone structures, it is highly recommended to visit during daylight hours when the natural light illuminates the interior of the caves.
Visitors can observe the 501 stone Rakan statues from a close distance, experiencing the quietude of the environment. The journey involves exploring the historical stone bridges and the intricate carvings of the stone caves. It is a perfect way to trace the historical context of the Iwami Silver Mine and connect with the stone-carving culture of Japan.
Rakan-ji is located within the "Omori Silver Mine Traditional Important Buildings Preservation District," a part of the World Heritage site. The surrounding area is rich with history, featuring sites such as the Kumagai Family Residence and the Iwami Silver Mine Museum (former Omori Magistrate's Office).
