History and Mission of the Museum
Protecting Treasures for Future Generations
The Koyasan Reihokan was established at a time when social changes following the Meiji period threatened the preservation of many temple treasures and historical artifacts. Plans for a dedicated treasure museum were approved in 1910, construction was completed in 1920, and the museum opened to the public the following year.
The first director was Doki Horyu, the head priest of Kongobuji Temple. Under his leadership, the Reihokan became an important center for protecting and managing the cultural properties preserved throughout Koyasan.
As the collection continued to grow, additional storage facilities were constructed. A large storage building known as the “Taihozō” was completed in 1961, followed by further modern conservation facilities in 1984 and 2003.
These facilities allow precious cultural properties to be stored under carefully controlled conditions while also making them accessible to visitors.
An Extraordinary Collection of Buddhist Treasures
Thousands of Priceless Cultural Properties
The greatest attraction of the Reihokan is the sheer scale and quality of its collection. It contains approximately 28,000 designated cultural properties, including 21 National Treasures, 148 Important Cultural Properties, 17 cultural properties designated by Wakayama Prefecture, and 2 Important Art Objects.
When non-designated historical materials are included, the collection contains approximately 100,000 items. The collection covers a remarkable range of Buddhist and historical art, including statues, paintings, calligraphy, manuscripts, ritual objects, crafts, and archaeological materials.
Together, these treasures provide valuable insight into the history, beliefs, artistic traditions, and intellectual culture of Shingon Buddhism.
Exhibitions That Change Throughout the Year
The museum presents both permanent displays and regularly changing special and temporary exhibitions. Because the exhibits are rotated periodically, even returning visitors may discover completely different works on each visit.
Special exhibitions may also provide rare opportunities to see valuable objects that are not normally displayed, making the museum especially appealing to visitors with a strong interest in Japanese art and Buddhist history.
Highlights of the Collection
Masterpieces of Japanese Buddhist Art
The Reihokan contains numerous works considered important in the history of Japanese art. Among the highlights is the “Nirvana Painting”, depicting the Buddha at the moment of his death. It is regarded as one of the oldest surviving works of its kind and is highly valued for its elegant artistic expression.
Another important work is the “Descent of Amida and the Holy Assembly”, which depicts Amida Buddha arriving to welcome the deceased into the Pure Land. The “Five Great Strength Bodhisattvas”, known for their powerful and imposing appearance, are another memorable example of Japanese Buddhist imagery.
Exceptional Buddhist Sculptures
The sculpture collection includes the famous Eight Great Attendants, traditionally attributed to the renowned Kamakura-period sculptor Unkei. Visitors can also admire outstanding Buddhist statues from the Heian period and observe how Japanese Buddhist sculpture evolved over the centuries.
These sculptures reveal differences in facial expressions, posture, clothing, and carving techniques from one historical period to another, offering a fascinating introduction to the development of Japanese Buddhist sculpture.
Calligraphy and Historical Documents
The collection also includes ancient manuscripts and documents, including writings traditionally attributed to Kobo Daishi Kukai, the founder of Koyasan and one of the most influential figures in Japanese Buddhism.
These materials are important not only as examples of beautiful Japanese calligraphy, but also as historical records that provide insight into the religious and cultural world of medieval Japan.
An Architectural Attraction in Its Own Right
A Blend of Japanese and Western Influences
The museum buildings themselves are also worth seeing. The original Main Building and Hokokaku Hall are designated as Registered Tangible Cultural Properties.
Built during the Taisho period, these structures feature a refined combination of traditional Japanese and Western architectural influences. Their calm atmosphere provides an appropriate setting for viewing Koyasan’s sacred treasures.
Exploring the architecture as well as the exhibits allows visitors to appreciate another layer of Koyasan’s cultural heritage.
How to Enjoy the Reihokan
Combine Your Visit with Koyasan’s Sacred Sites
The Koyasan Reihokan is more than a conventional museum. It is an ideal place to deepen your understanding of the history and spiritual culture of Koyasan.
After visiting the museum, travelers can continue to Okunoin, Danjo Garan, and the surrounding temples. Seeing the actual religious sites after learning about their history and artistic treasures can make a visit to Koyasan considerably more meaningful.
The museum’s peaceful environment also encourages visitors to slow down and spend time carefully observing the artworks. For many travelers, this quiet encounter with Japanese Buddhist art becomes one of the most memorable parts of a Koyasan journey.
Seasonal Special Exhibitions
Throughout the year, the museum organizes exhibitions focusing on particular themes, periods, temples, or types of cultural property. Some exhibitions feature rare treasures that are not usually accessible to the public.
If you have a particular interest in Buddhist art or Japanese history, checking the exhibition schedule before your visit is highly recommended.
