With over 1,000 years of history, Akaiwasan Koonji Temple is a precious ancient temple in the Kanto region. With plenty to see, including a 70-tatami dragon ceiling painting, a 5-meter reclining statue, and a Nagayamon gate dedicated to academic success, there is something new to discover every time you visit. Be sure to visit this temple, where history, culture, and architectural beauty come together.
Akaiwayama Koonji Temple is a Shingon Buddhist temple located in Chiyodamachi, Oura County , Gunma. The current head priest has been the head priest for 84 generations, and the temple is considered one of the few sacred places in the Kanto region with a history of over 1,000 years.
Its origins date back to the Nara period, when Kobo Daishi (Kukai) stayed in the area in 814 and rebuilt it as a training center for Esoteric Shingon Buddhism. Since then, Koonji Temple has been passed down as a temple of the Koyasan Shingon sect, which regards Kobo Daishi as its founder.
When you step into the main hall, the first thing that catches your eye is the huge ceiling painting of a dragon, which spans an area of 70 tatami mats. The dragon exudes a strong presence as the guardian deity of the temple, as if watching over the worshippers from the ceiling.
Inside the main hall, you will find a 5-meter tall statue of Shaka Nyorai in nirvana. This space was designed by world-renowned architect Takaharu Tezuka, and is a religious space that recreates the Shaka Nyorai statue in nirvana in three dimensions. You will be so moved by its majestic appearance that you will be left speechless.
The Amida Hall houses a statue of Amida Nyorai, believed to have been erected during the Kamakura period. This statue, designated as an Important Cultural Property by the prefecture, continues to soothe the hearts of visitors even after so many years.
A beautiful bamboo forest surrounds the main hall, and the elegant sounds of the bamboo can be heard every time the wind blows. It's a quiet and relaxing space, as if you've wandered into another world.
Within the temple grounds is the Nagayamon Gate, known as the "Gate of Success." It is said that passing through this gate will bring you good fortune in your academic success, and many students and those about to take qualification exams visit the gate.
This Nagayamon gate has a special history. It is said that Japan's first female doctor, Ogino Ginko, passed through this gate with the determination to make her wish come true when she left the countryside to move to Tokyo. Passing through this gate while feeling her strong will to pave the way in an era when women were not allowed to become doctors will be a special experience.
