Onjo-ji Temple (Mii-dera)

Onjo-ji Temple (園城寺), also known as Mii-dera, is a significant historical and spiritual site, revered as the head temple of the Tendaijimon Buddhist sect. Established by Prince Otomo Yota no O, the temple’s name and structure have evolved over time, influenced by emperors Tenji, Kobun, and Tenmu. The temple's current name, Mii-dera, meaning "Temple of the Three Wells," is derived from the sacred spring where the emperors Tenji, Tenmu, and Jito once bathed, a water source that holds deep historical and cultural significance. This spring also played a role in the Sanbu Kanjo ritual, performed by the great Buddhist teacher Chisho, symbolizing a rite of passage.

Throughout its long history, Mii-dera has endured multiple fires, yet it has been carefully restored by influential figures such as Hideyoshi Toyotomi and Ieyasu Tokugawa. Today, the temple stands as both a National Treasure (Koku-ho) and an Important Cultural Property (Juyo Bunkazai), reflecting its enduring cultural importance. Nestled amidst tranquil gardens, Mii-dera offers a peaceful atmosphere where visitors can immerse themselves in Japan’s rich spiritual and architectural heritage, making it a must-visit destination for those seeking to explore the country’s deep cultural roots.
