A Building Inside a Building
Saimyoji Zushi in the Main Hall (西明寺本堂内厨子, Saimyō-ji Hondō-nai Zushi) is a lacquered miniature shrine standing on the altar platform inside the main hall of Saimyoji at Mashiko, Haga District, Tochigi Prefecture, dated by the Agency for Cultural Affairs to 1394 and designated a national Important Cultural Property on 21 June 1962.
A zushi is a cabinet built to house a Buddhist image, and the finest examples are not furniture but architecture in miniature, framed with the same members a full-sized hall would use. This one is a single-bay structure with a hōgyō pyramidal roof of boards, its exterior finished in black lacquer.
The carpentry is dense. Three-tiered bracket complexes sit above the columns, and further brackets fill the spaces between them, producing the packed arrangement Japanese carpenters call tsumegumi. The eaves carry two tiers of fan rafters. Look at the curve of the kayaoi, the fascia along the eave edge, and at the battening of the roof boards: Mashiko's municipal record notes that the technique matches the work on the temple's three-storied pagoda, and that the whorl carving on the beam-end noses closely resembles that on the gate's tie beams.
Smaller flourishes accumulate. The upper portions of the columns are wrapped in a brocade pattern. The hinged karado doors carry a set of twelve panel designs, and no two of the twelve repeat.
Two Dates, One Cabinet
The zushi presents a genuine chronological puzzle, and the Agency for Cultural Affairs states both sides of it in its own records.
An ink inscription on an interior column reads Ōei 1, corresponding to 1394, and this is the date the Agency enters in its ledger and the one the temple and the town both cite. The temple's chronology fits it neatly: in 1394 the patron Mashiko Katsunao is said to have rebuilt the temple halls after a fire.
The Agency's descriptive commentary reaches a different conclusion. It observes that the present main hall dates only to 1601, so the zushi is a survival from an earlier hall, and then argues from the handling of the detail that the cabinet was made at the same time as the gate, which it places in 1491 to 1492. That is a gap of roughly a century.
Neither reading has been set aside. An inscription can record a rebuilding of the hall rather than the making of the cabinet inside it, and stylistic argument can mistake a conservative workshop for a later one. Anyone standing in front of the zushi is looking at an object whose date remains under discussion, which is a more interesting position than certainty.
The designation came in 1962, half a century after the pagoda and gate were listed, and it covers one structure together with an appended ridge tablet. Whichever date proves correct, the zushi is a rare Muromachi survival of its type in the eastern provinces, and it preserves inside a later hall the detailing of a building that no longer exists.
Getting Inside to See It
Of Saimyoji's three Important Cultural Properties, this is the one you cannot see from the path. The pagoda and the gate stand in the open air; the zushi sits on the altar platform in the inner sanctum, and reaching it means paying the 300 yen the temple asks of anyone entering that part of the main hall.
It is money well spent for a second reason. The inner sanctum also holds a group of Kannon figures carved in the Kamakura period, among them Shō Kannon, Batō Kannon, Senju Kannon, Enmei Kannon, Nyoirin Kannon and Seishi Bosatsu, protected as prefectural cultural properties and displayed together in one room.
The principal image of the temple, a wooden eleven-headed Kannon, is kept inside the zushi itself and is a hibutsu, a hidden image not shown to visitors. The cabinet stays closed. What you are looking at is the container, and the container is the designated property.
Reception hours run 8:00 to 17:00 from April through October and shorter in winter, with the temple's own listing and the Bando pilgrimage association's differing slightly on the winter closing time, so call ahead between November and March. Assume that photography inside the main hall is not permitted unless you ask and are told otherwise.
Saimyoji sits on the southern slope of Dokkosan above Mashiko, the twentieth station of the Bando Kannon pilgrimage. Trains run to Mashiko Station on the Moka Railway via Shimodate; no bus connects the station to the temple, so a taxi or car covers the last stretch, about 30 minutes from the Moka or Sakuragawa-Chikusei interchanges for drivers.

Q&A
- Can visitors see the Saimyoji Zushi in the Main Hall, and what does it cost?
- Yes, but it requires entering the inner sanctum of the main hall, for which the temple asks 300 yen. The zushi is not visible from outside the hall. The precincts themselves are free to enter.
- What is inside the Saimyoji Zushi in the Main Hall?
- The temple's principal image, a wooden eleven-headed Kannon, is enshrined inside. It is a hidden image and the doors remain closed, so visitors see the exterior of the cabinet rather than the sculpture.
- How old is the Saimyoji Zushi in the Main Hall?
- An interior column bears an ink inscription of 1394, which the Agency for Cultural Affairs records as its date. The same agency's commentary argues from the carving that it may instead be contemporary with the temple gate of the 1490s. Both readings remain in circulation.
- Why is the Saimyoji Zushi older than the hall that contains it?
- The present main hall was built in 1601. The zushi survived from an earlier hall on the same site and was installed in the new building, so it preserves detailing from a structure that has otherwise been lost.
- What else can I see in the inner sanctum at Saimyoji?
- A group of Kamakura-period Kannon sculptures stands in the inner sanctum, including Shō Kannon, Batō Kannon, Senju Kannon, Enmei Kannon, Nyoirin Kannon and Seishi Bosatsu, designated as prefectural cultural properties.
