Hofuku-Ji Temple Treasure House

Hofukuji Hozo: A 1793 Storehouse Armored in Namako Plasterwork

Behind the kitchen quarters of Hofukuji in Soja City, Okayama Prefecture, stands the temple's hozo, or treasure store, a two-story earthen-walled kura completed in 1793 (Kansei 5). Oriented east to west, it measures 7.9 by 4.9 meters, about 39 square meters, under a simple gabled roof of sangawara tiles. Small beside the great hojo and Buddha hall, it may be the most carefully finished building on the grounds.

Its skin is the show. The walls are sealed in thick white plaster, and the lower portions are wrapped in namako-kabe: square dark tiles set on the diagonal, their joints raised in rounded white ridges said to resemble sea cucumbers, which give the technique its name. At each of the four corners, the namako work climbs the full height of the wall to the plaster band, the hachimaki, beneath the eaves, turning the corners into armored piers. More namako panels and slim water-shedding tile courses protect the upper gables and the sills below the windows, every point where driven rain would strike.

A kura of this kind was the fireproof safe of an Edo-period temple. Hofukuji, a regional head temple of the Rinzai Tofukuji school and the boyhood training place of the painter Sesshu (1420-1506), had learned the lesson of fire the hard way: its medieval compound burned in 1575, leaving only the pagoda of 1376. The 1793 storehouse was built so that what the temple valued would survive the next disaster.

Why the Storehouse Was Registered

The hozo was registered as a national Tangible Cultural Property on January 8, 2009, under number 33-0207, in the category of structures that would be difficult to reproduce today. The official record singles out its exceptionally careful construction.

The judgment is easy to verify by eye. Namako-kabe survives across western Japan on merchant storehouses, but the full-height corner treatment, the coordinated water-shedding courses at gable and sill, and the discipline of the plasterwork here represent craft standards that modern budgets and trades rarely reach. Among the ten Edo-period structures of Hofukuji registered in 2009, the hozo is the one honored specifically for the difficulty of ever making its like again.

What to Look For

Circle the building slowly. On the long walls, the namako lattice stays low, guarding the base; at each corner it suddenly rises in a full-height band to the plaster hachimaki under the roof. The alternation of flat white plaster, glossy dark tile, and rounded white joints changes with every hour of light.

Then check the details that show a plasterer thinking about water: the slim tile courses that cap the namako panels below the windows, and the protective work high in the gables where wind-blown rain hits hardest. The storehouse stands behind the kitchen quarters, so view it in passing along the paths; its contents are not on display, and the building is appreciated from outside.

Pair it with the two registered wells beside the kitchen, the tenzo well and the naka-ido, to read the working, backstage side of the monastery, then return to the ceremonial front of Buddha hall and hojo. Grounds and parking are free, and the maples of mid-to-late November are the classic season to visit.
