The Yakushi-do hall, designated an Important Cultural Property of Japan, is a graceful structure retaining the architectural features of mid-Muromachi period Zen temple style.
Byodoji Temple is a Soto Zen Buddhist temple located in Iwaya, Aga-machi, Higashi蒲原gun, Niigata Prefecture. Tradition holds that it was founded by Taira no Kiyomori, a warrior from the late Heian period. The story goes that while traveling downriver by boat, Kiyomori discovered a small, glittering golden Yakushi Nyorai (Medicine Buddha) statue, which he then enshrined in the Yakushi-do hall. Initially named Heitoji Temple, supposedly to commemorate the Taira clan's retainers, the name was later changed to avoid offending the Kamakura Shogunate. The existing Yakushi-do hall was built in 1519 (Eisho 16) by the monk Eigen and was designated a National Important Cultural Property on February 28, 1923 (Taisho 12). The hall features ancient graffiti left by past worshippers; particularly noteworthy are inscriptions from 1578 (Tensho 6) by soldiers of the Ashina clan, offering invaluable insight into the era. This graffiti provides a precious glimpse into the tense relationship between Aizu and Echigo provinces, making it a must-see for history buffs. Also on the temple grounds is the Shogun-sugi cedar, a designated National Natural Monument. Estimated to be over 800 years old, this giant tree evokes a profound sense of history. The combination of the Yakushi-do hall, the Shogun-sugi cedar, and the serene mountain landscape creates a peaceful atmosphere, offering visitors a tranquil escape. Byodoji Temple, a place where history and nature harmoniously coexist, is ideal for refreshing both mind and body.
