A Building Inside a Building
Daihoji Kannondo Zushi oyobi Shumidan (大法寺観音堂厨子及び須弥壇, also written with the variant character 須弥檀), the miniature shrine and altar platform standing inside the Kannon Hall of Daihoji Temple in Togo, Aoki Village, Chiisagata District, Nagano Prefecture, was made in the early Muromachi period and designated an Important Cultural Property on 19 July 1952.
Two objects share one designation, counted together as a single set. A zushi is a cabinet built to house a Buddhist image, made as a scaled-down building rather than a box. A shumidan is the raised platform it sits on, named for Mount Sumeru, the world-mountain of Buddhist cosmology.
The Agency for Cultural Affairs describes the zushi as ikken zushi, one bay wide, with an irimoya roof, the hipped-and-gabled form that ranks above a plain gable in the hierarchy of Japanese roof types. The roofing is hongawara-gata itabuki: wooden boards worked to imitate the alternating flat and rounded courses of a full tile roof. A carpenter cut curves into planks so that a cabinet indoors would carry the roof of a temple hall. The shumidan is recorded as karayo in style with a koran railing running around it. The designation number is 01172, and the Agency dates the set between 1333 and 1392.
Japanese Frame, Chinese Fittings
Daihoji is better known for the building above the Kannon Hall on the slope: a three-storied pagoda erected in 1333, called the Mikaeri no To, the pagoda you turn back to look at. It became an Important Cultural Property as early as 1899 and was raised to National Treasure status on 31 March 1953, the year after the zushi and shumidan received their own designation.
The Agency's commentary on the pagoda calls its carpentry jun-wayo, purely Japanese style, the idiom that developed from Nara and Heian precedent. Then it notes something else. The Buddhist altar at the pagoda's centre mixes karayo into that Japanese frame, using finely cut koma panels and distinctive giboshi finials. Karayo, the Chinese-derived manner that entered Japan with Zen Buddhism in the Kamakura period, is a different architectural language: lighter members, more elaborate bracketing, tighter ornament.
Which is what makes the Kannon Hall set worth attention. The shumidan there is registered as karayo shumidan outright. Across two separate structures at one temple, the buildings speak Japanese and the altar furniture speaks Chinese. Fourteenth-century carpenters in this valley evidently treated the two idioms as tools for different jobs, reserving the imported vocabulary for the fittings that framed the sacred image.
The temple itself is old enough to have accumulated such layers. Daihoji's own account traces its founding to the Taiho era, between 701 and 704, as the temple attached to Urano station on the Tosando, one of the ancient highways radiating out of the capital. It belongs to the Tendai school under the mountain name Ichijosan.
The Oldest Shachihoko in Japan, and How to See It
Look at the ridge ends of the zushi roof. Two shachihoko grip the tiles.
A shachihoko is an imaginary creature with the head of a beast and the body of a fish, later familiar from the gilded pair on Nagoya Castle. The temple dates this pair to the end of the Kamakura period or the beginning of the Muromachi period and identifies them as the oldest surviving examples in Japan. They came under protection with the rest of the set in 1952.
The two are not identical. The one on the right as you face the shrine has the larger fangs and is taken to be male, the one on the left female. Neither simply perches. Both bite down on the roof, jaws clamped over the edge, which gives the pair an animation that later castle ornaments traded away for symmetry. The creature's belly was thought to hold water, so a shachihoko was set on a roof to put out fire, and the temple treats the pair as protection against fire and misfortune generally.
Access works on two levels. Ordinary admission is 300 yen for adults, 200 yen for holders of a disability certificate and 100 yen for elementary and junior high school students. The temple opens 9:00 to 17:00 from April through October and 9:00 to 16:00 from November through March. On a clear day, the zushi can be made out from outside the Kannon Hall, and the shachihoko with it, which means the roof ornaments cost nothing beyond the entrance fee.
Going in costs more. A special viewing at 700 yen opens the hall interior and brings the shachihoko, the Eleven-Headed Kannon and the Fugen Bodhisattva into close range; the two images stand behind the zushi and cannot be seen otherwise. Ask at the temple office about photography inside the hall, since restrictions apply and the staff will explain what is permitted.
Getting there: a Chikuma Bus on the Aoki line takes about 25 minutes from Ueda Station, and the temple is roughly 15 minutes on foot from the Togo stop. The Aoki Village Local Art Museum beside the approach path holds a reconstructed copy of the wall paintings that once covered the pagoda's interior, whose originals have flaked away almost entirely. It also runs a tearoom.

Q&A
- What exactly is the Daihoji Kannondo Zushi oyobi Shumidan?
- It is a pair of objects designated together as one set: a zushi, a cabinet built like a miniature building to house a Buddhist image, and the shumidan, the raised altar platform it stands on. Both are inside the Kannon Hall at Daihoji in Aoki Village, and the Agency for Cultural Affairs dates them to the early Muromachi period, between 1333 and 1392.
- Can visitors see the Daihoji Kannondo Zushi oyobi Shumidan without paying extra?
- Partly. The temple states that on a clear day the zushi is visible from outside the Kannon Hall, so ordinary admission of 300 yen for adults is enough to make out the shrine and the shachihoko on its roof. Entering the hall requires the 700 yen special viewing, which also covers the Eleven-Headed Kannon and the Fugen Bodhisattva standing behind the zushi.
- Why are the shachihoko on the Daihoji zushi significant?
- The temple identifies them as the oldest surviving shachihoko in Japan, made at the end of the Kamakura period or the start of the Muromachi period. The right-hand figure has larger fangs and is taken to be male, the left female, and both bite down on the roof rather than merely sitting on it. They were protected along with the rest of the set in 1952.
- What are the opening hours and admission fees at Daihoji Temple?
- Daihoji opens 9:00 to 17:00 from April through October and 9:00 to 16:00 from November through March. Admission is 300 yen for adults, 200 yen for holders of a disability certificate and 100 yen for elementary and junior high school students, with the special hall viewing at 700 yen. Advance booking is needed for prayer services.
- How do visitors reach Daihoji Temple in Aoki Village?
- Take a Chikuma Bus on the Aoki line from Ueda Station, ride about 25 minutes, get off at Togo and walk roughly 15 minutes. The temple sits at 2052 Togo, Aoki Village, near Bessho and Kakeyu hot springs, and pairs naturally with the National Treasure pagoda at Anrakuji in the same district.
