Renge-in Tanjō-ji, Buddhist temple in Tamana, Japan

Renge-in Tanjō-ji is a Shingon Ritsu temple in Tamana with a Main Temple and an Oku-no-in on Mt. Shōdai, 4 km north. The Main Temple has a reinforced-concrete main hall from 1966, a wooden five-story pagoda completed in 1997, a Great South Gate of Aomori hiba built in 2011, and a two-story pagoda completed in 2018.

The temple was originally established as Jōkō-ji Renge-in during the Heian period, but was destroyed during the Sengoku period. After more than 400 years, it was reconstructed in the 1930s under its current name.

The temple serves as a gathering place for monthly ceremonies on the 13th, where monks chant sutras and share teachings. These gatherings show how the space remains central to the spiritual practice of the local community.

The temple sits in a quiet area that is easy to explore on foot, allowing plenty of time to wander through its grounds. Visitors should know that certain areas may have restricted access during ceremonies, so checking ahead on accessible days is helpful.

The Ryūbi-kudari takes place on the night of June 12, not in summer: devotees walk with lanterns from Oku-no-in on Mount Shōdai to the Main Temple, ahead of the Great Festival on June 13, the date Kōen is said to have entered the pond at Sakuraga-ike in 1169.
