A Turning Library in a Corner of the Compound
Tucked into the southwest corner of the East Temple grounds in Yokkaichi stands a small, square, whitewashed building that most visitors walk straight past. It is the Kyozo, the sutra repository, and it is the oldest surviving structure in the whole compound, completed in Kansei 11 (1799), roughly eighty years before the great main hall behind it.
The building is compact, a three-bay square with a building area of only about 28 square metres. It is a dozo, a fireproof storehouse of thick earthen walls, raised on a base of cut stone laid up in three stepped tiers. The point of all that mass is protection: sutras are paper, and paper burns, so the community that owned them built something closer to a strongbox than a hall.
The Wheel Inside
What makes this repository more than a storehouse sits at its centre. Inside is an octagonal rinzo, a revolving sutra case that turns on a central axle. The idea, old in Buddhist practice, is that setting the wheel in motion carries the same merit as reading the scriptures it holds: a library that rotates rather than one you read shelf by shelf.
The interior is finished to match that purpose. The floor is laid in a grid pattern with plaster joints, and overhead runs a coffered ceiling with raised borders, a treatment usually reserved for spaces of some ceremony. For a building barely five metres across, the care taken inside is out of proportion to its size, and that is exactly what the registration recognises.
Look up at the exterior and the roof declares its rank. It is built in the hogyo (pyramidal) form under formal hongawara tiling, and a single-bay offering porch projects at the front, roofed with a copper-sheathed karahafu, an undulating cusped gable. A copper-roofed porch on a small plaster storehouse is a deliberate flourish, the builders dressing up a utilitarian type.
Why It Matters, and What to Notice
In 2009 the Kyozo was placed on the national register of Tangible Cultural Properties (registration number 44-0167), one of five structures at the temple registered together as a group and recognised as a well-made example of its kind. It received repairs in the early Meiji years, but its late-Edo character survives.
On a visit, start with the stone base and read it as three clean steps rising to the walls; then find the front porch and pick out the copper gable against the white plaster. If the doors happen to be open during a temple event, the octagonal case within is the thing to see: the reason a storehouse earned a copper-roofed porch and a coffered ceiling. The rest of the year, the pleasure is quieter: the oldest walls on the grounds, standing in the corner while the larger buildings take the attention.

Q&A
- How old is the sutra repository?
- It was completed in 1799 (Kansei 11), with repairs in the early Meiji period. That makes it the oldest surviving building in the East Temple compound, predating the 1880 main hall.
- What is the octagonal case inside?
- It is a rinzo, a revolving sutra repository. Turning it is traditionally held to confer the merit of reading the scriptures stored within, so the building functions as a rotating library.
- Why is such a small building registered?
- Despite its size, it is unusually finely built: a fireproof earthen storehouse with a stone base, a copper-roofed porch, and a coffered interior ceiling. It was registered as a carefully made example of its type.
- Can the interior be seen?
- The repository is not routinely open. Interior access depends on temple activities, so ask on-site and follow any posted guidance rather than assuming entry.
