Onsenji Temple

Onsenji Temple (温泉寺), nestled in the heart of Arima Onsen, offers travelers a unique glimpse into the spiritual roots of Japan’s most famous hot spring town. Within its grounds lies Onsenji Misoshian, a cultural exhibition hall that showcases the rich history of Arima’s onsen through detailed picture scrolls and historical artifacts. These works depict the legendary origins of the hot springs and highlight the contributions of two revered Buddhist priests—Gyoki and Ninsai. Gyoki, a central figure in Japanese Buddhism, was the first priest ever granted the prestigious title of daisoji. Visitors can also discover Negai no Niwa (“Garden of Wishes”), a tranquil garden featuring a statue of Gyoki, surrounded by greenery and quiet paths ideal for reflection.

Beyond its role as a temple, Onsenji acts as a cultural bridge between Buddhism and Japan’s onsen heritage. Gyoki, who studied under the legendary monk Genjo Sanzo, is believed to have inspired Sanzohoshi, the monk character in the Chinese literary classic Saiyuki (Journey to the West). This unique connection between literature, spirituality, and healing waters makes Onsenji a compelling stop for curious travelers. Although Onsenji Misoshian has been closed for maintenance since August 2022, the temple grounds remain open to the public, offering a peaceful, spiritual retreat amidst the bustling streets of Arima Onsen.
