A Dated Bell from 1280 on Mount Koya
A bronze bell can be hard to date. Casting techniques changed slowly, and a plain bell offers few clues to the year it left the foundry. This one removes the guesswork. An inscription on its body records that it was reverently cast on the twenty-fifth day of the first month of Koan 3, a date that falls in the year 1280, during the Kamakura period. The Japanese word used, hochu, carries the sense of a casting made as a religious offering.
The bell belongs to Kongobuji, the head temple of Koyasan Shingon Buddhism, in Koya-cho in the mountains of Wakayama Prefecture. Koyasan was opened in the early ninth century by the priest Kukai and grew into one of the great centers of esoteric Buddhism in Japan, a monastic town set high on a forested plateau. A firmly dated object like this bell helps anchor the broader history of the mountain's metalwork and ritual furnishings.
Why It Matters
The value of the bell rests largely on that single line of inscription. Many medieval Japanese bells survive without any record of when or for whom they were made, so the survivors that do carry a clear, cast-in date become reference points for everyone who studies the craft. Specialists can compare an undated bell against a securely dated example like this one and reason about its age from the shape of the crown, the spacing of the raised bands, and the proportions of the body.
The year itself sat in a tense decade. The first Mongol invasion had struck in 1274, and a second, larger attempt would come in 1281, the year after this bell was cast. Across the country, temples and shrines were caught up in prayers for the country's protection. The bell was designated an Important Cultural Property on August 25, 1925, recognized for its documented Kamakura date and its place among the bells preserved at Koyasan.
Seeing the Bell
The designated art and craft holdings of Koyasan are looked after by the Koyasan Reihokan, a museum that opened in 1921 to gather and protect the mountain's treasures, and which is run today by the Koyasan Cultural Properties Preservation Society, the body listed as this bell's custodian. The Reihokan holds the great majority of Koyasan's designated paintings, sculpture and metalwork, and it rotates them through seasonal and special exhibitions rather than showing everything at once. A particular piece may be on view during one exhibition and resting in storage during the next.
For that reason, anyone hoping to see this bell should check the museum's current exhibition schedule before traveling, or contact the Reihokan to ask. A visit pairs naturally with the rest of the mountain: the Danjo Garan temple complex, the Konpon Daito pagoda, and the long cedar avenue leading to Okunoin, the inner sanctuary. The Reihokan stands a short bus ride from Koyasan Station, at the Reihokan-mae stop.

Q&A
- How do we know the year it was made?
- The bell carries a cast inscription dating it to the first month of Koan 3, which corresponds to 1280, in the Kamakura period.
- Who owns it?
- It belongs to Kongobuji, the head temple of Koyasan Shingon Buddhism, and its designated holdings are cared for by the Koyasan Reihokan.
- Can I see it on any given day?
- Not necessarily. The Reihokan rotates its designated objects through exhibitions, so the bell is not always on display. Check the schedule before you go.
- Why is a single date so important?
- Most medieval bells are undated. A securely dated bell becomes a yardstick that helps scholars estimate the age of others by comparing form and proportion.
- Where is the Reihokan?
- In central Koyasan, Koya-cho, Wakayama Prefecture, a short Nankai Rinkan bus ride from Koyasan Station to the Reihokan-mae stop.
