Risai Family Residence Storehouse

A ten-bay storehouse on a quiet Kaizuka corner

Walk the west edge of Kaizuka's old merchant grid and one long white wall keeps going far past the point where you expect it to stop. This is the storehouse, or dozō, of the Risai house: a two-story building of thick plastered earthen walls, running roughly eighteen meters along its street face. Its frontage measures ten ken (a ken is about 1.8 meters), while the depth is an ordinary two. The building covers about 127 square meters and dates to the late Edo period, somewhere between the middle of the eighteenth century and the early nineteenth. It was raised as a sode-gura, a wing storehouse joined to the west side of the family's main house, and it faces the lane known as Osage-suji.

Medicine merchants in a town that governed itself

Kaizuka grew up around Gansen-ji, a Jōdo Shinshū temple, and for more than two and a half centuries it was something unusual in Japan: a jinaichō, a temple town that ran its own affairs. From 1610 the head-priest Bokuhan family held a black-seal charter granted by Tokugawa Ieyasu and governed the town as its lord, standing outside the surrounding Kishiwada domain until the early Meiji land reforms.

The Risai family were leading townspeople here. By their own genealogy an ancestor settled in Kaizuka after the military upheavals of 1581, and the house took the hereditary name Magozaemon. They ran a wholesale trade in yakushu, the dried plants and minerals used to compound traditional medicine, and for most of the Edo period they served as town elder of the northern ward, Kitamachi. Their corner plot sat just north of the Bokuhan office, the seat of the town's government.

What "registered" means here

The storehouse is a Registered Tangible Cultural Property, recorded in March 2003. Registration is worth pausing on, because it is not the same thing as designation. Japan's stronger label, used for National Treasures and Important Cultural Properties, is "designation" (shitei) and carries tight controls over any change to the building. "Registration" (tōroku), introduced in 1996, is a lighter instrument aimed at the far larger stock of older buildings that give a place its character: structures generally past their fiftieth year that contribute to the historic landscape. Owners need only notify the authorities before making alterations, which allows families to keep living in and using the buildings. The Risai storehouse was listed under exactly that criterion, as a building that shapes the country's historic scenery, together with the main house and a 1920s annex.

Reading the building from the street

You cannot go inside. The Risai house remains a private home, and the registered townhouses of Kaizuka are as a rule closed to visitors. The storehouse still rewards a slow look from the lane. Behind that long wall the interior was split into two rooms across its five-ken length: the southern half stored the family's medicinal stock, the northern half held clothing and household tools, a division that mirrors the family business in the plan of the building itself.

The roof carries a more recent story. After the Great Hanshin-Awaji earthquake of 1995, the Kobe earthquake, the heavy formal tiling (hongawara) was replaced with lighter pantiles (sangawara), the same change made to the main house. It is a quiet piece of seismic prudence set into the roofline.

Around the temple town

The real pleasure here is the walk. From Nankai Kaizuka Station the old town is four or five minutes on foot, and the Edo street grid survives almost intact. At its center stands Gansen-ji, known affectionately as Bokkan-san, whose main hall (1663), front gate (1679), drum tower (1719) and other structures are Important Cultural Properties open to visitors. A short stroll away, the Kaizuka Jinaicho Machiya-kan, housed in the former Tanaka residence, lets you step inside a merchant townhouse, while reused houses such as the broad Hiromi residence punctuate the lanes. Thirteen of the town's houses hold the same registered status as the Risai storehouse, so the whole district reads as a single preserved streetscape rather than a string of separate attractions.
