Onjo-ji Temple (Mii-dera)

Onjo-ji Temple (園城寺), also known as Mii-dera, is a revered historical site and the head temple of the Tendaijimon Buddhist sect. Founded by Prince Otomo Yota no O, the temple’s name and structure were later modified by emperors Tenji, Kobun, and Tenmu. The name Mii-dera, meaning "Temple of the Three Wells," originates from the sacred spring where emperors Tenji, Tenmu, and Jito received their first baths. This same water was later used by the great Buddhist teacher Chisho in the Sanbu Kanjo ritual, a symbolic rite of passage.

Despite enduring multiple fires throughout history, Mii-dera has been meticulously restored by historical figures such as Hideyoshi Toyotomi and Ieyasu Tokugawa. Today, it is recognized as a National Treasure (Koku-ho) and an Important Cultural Property (Juyo Bunkazai). Surrounded by serene gardens, this iconic temple stands as a testament to Japan’s rich spiritual and architectural heritage.
