The collection contains over 28,000 items, though only a small fraction are displayed at any given time to ensure preservation.
The museum holds specific 'Seated Dainichi Nyorai' statues that are considered masterworks of Heian-period sculpture.
Several of the exhibited mandalas are 'Ryokai Mandala,' which are foundational to Shingon Buddhist iconography.
The museum archives include rare ancient documents that provide insight into the medieval economic and social history of Koya-san.
Some statues on display were originally housed in temples that have since been destroyed by fire or natural decay.
Koyasan Reihokan Museum serves as the primary repository for the cultural and religious heritage of Mount Koya, housing thousands of artifacts from various sub-temples of the Kongobu-ji complex. The museum was established in 1921 to preserve and exhibit Buddhist art that had become difficult to maintain within individual temple buildings. Its permanent collection includes National Treasures and Important Cultural Properties, primarily dating from the Heian and Kamakura periods. Visitors encounter a rotating selection of mandalas, wooden and metallic Buddhist statuary, and ancient sutra scrolls. The institution maintains a climate-controlled environment to protect delicate silk paintings and wooden icons from the mountain's humid atmosphere. It functions as both a research facility and a public gallery, documenting the evolution of Shingon Buddhism. The architecture itself reflects a blend of traditional Japanese aesthetic principles and modern institutional design. Many of the displayed items are original votive offerings from the surrounding monastic community.
