A 1920s Annex Behind an Edo Medicine Merchant's House
Walk the quiet lanes of Kaizuka's old temple town and you pass one Edo-period frontage after another: low tiled roofs, lattice fronts, plastered storehouses set hard against the street. At the corner where two old routes meet stands the home of the Risai family, who sold medicines here for generations and answered, head of household after head of household, to the name Magozaemon. Behind their main house, across a small inner courtyard, sits a building that breaks the rhythm of the street in a quiet way. It is the hanare, a detached annex completed around 1924, and it carries a surprise on its upper floor.
The Risai family traces its arrival in Kaizuka to the upheavals of the late sixteenth century. According to a genealogy kept by the household, an ancestor named Shikibu had taken vows at Matsuoji, a Tendai temple in what is now Izumi City, before settling in Kaizuka after Oda Nobunaga's campaigns of 1581. The family went into the wholesale medicine trade and held the post of town elder for Kita-no-chō through most of the Edo period. Their compound reflects that long tenure. The main house, whose original form may reach back to the seventeenth century, faces south onto Hori-no-chō-suji; a storehouse fronts the western lane; and the annex stands behind, screened from the street by the older buildings.
The annex itself is modest in footprint, about 91 square meters. It is built of wood, a single story for most of its plan, with a small second floor pushed to the western end under a tiled roof. Downstairs, two tatami rooms of eight and six mats open into one another as a linked parlor in the familiar Japanese manner. Climb the stairs, though, and the mood changes entirely.
The Western Room Upstairs
The single room on the upper floor is a yōma, a Western-style room, and it was clearly built to impress a guest. A fireplace anchors one wall, its surround set with decorative tiles. Daylight comes through stained glass worked into the windows. The original light fittings still hang in place. Taken together, these are the marks of the eclectic taste that spread among prosperous Japanese households in the Taishō years, when families who had made their money in older trades furnished a room or two in the manner of contemporary Europe while keeping the rest of the house thoroughly Japanese.
It is worth being honest about what survives and what does not. The 1995 earthquake that struck the Kobe region left its mark here, and repairs followed: the outer walls were refinished, and the wall covering of the Western room was replaced. The serious decorative work, however, came through. The fireplace tiles, the stained glass, the lighting, these are the fittings that make the room what it is, and they remain. A visitor who could stand in that room would be looking at the genuine 1920s interior, not a reconstruction of it.
There is something telling in the choice itself. An old medicine-trading family, rooted in a town governed for centuries by the head priests of a Pure Land temple, chose in the 1920s to add a fashionable foreign room to a compound built around tatami and timber. The annex is small, but it records a moment when a long-established merchant household looked outward.
Registered, Not Designated: What That Means
Japan protects its built heritage in more than one way, and the distinction matters when you read about a place like this. The strictest tier covers National Treasures and Important Cultural Properties, where the state designates a building and oversees its conservation closely. The Risai annex belongs to a different and lighter category: it is a Registered Tangible Cultural Property, listed under a system introduced in 1996 for buildings roughly fifty years old or older that help preserve the country's historic landscape. Registration encourages owners to keep and maintain their buildings while leaving them more freedom to live in and adapt them than designation would allow.
The annex was registered on 18 March 2003, as registration number 27-0228, on the criterion that it contributes to the historic landscape of the nation. The main house and the storehouse were registered on the same day, so all three Risai buildings carry the listing together. They sit within a wider cluster: many neighboring houses in the temple town were registered in the same period, which is part of why the district reads so coherently as you walk it.
The Temple Town Around It
The Risai house is a private home, and that shapes how you experience it. There are no open hours, and the annex stands behind the main house, so it is not really a building you view from the street. What you can do is read it in context, as one piece of a temple town that has kept its shape for four centuries.
That town is Kaizuka Jinaichō, which grew up around the temple now called Gansenji, known locally as Kaizuka Gobō or, affectionately, Bokkan-san. Recognized as a temple town under the Ishiyama Honganji in 1555 and burned in Nobunaga's wars two decades later, Kaizuka briefly served as the head temple of the Jōdo Shinshū sect in the 1580s when the abbot Kennyo moved his base here. In 1610 Tokugawa Ieyasu granted the community a sealed letter exempting it from various duties, and the Bokuhan family, the temple's head priests, governed the town as its lords for more than 260 years, until the early Meiji period. The town answered to no feudal domain and was not under direct shogunal rule, an unusual arrangement that helped fix the street plan and many of the buildings you still see.
Gansenji is open to visitors and makes a natural starting point. From there, the lanes invite slow walking past registered merchant houses, plastered storehouses, and the four temples that line one of the main streets. For a look inside a traditional townhouse, the Kaizuka Jinaichō Machiya-kan, a former merchant residence now run as a small museum, lets you step into the kind of interior that the Risai main house also preserves. If you can time a visit to mid-March, several of the old houses open for an annual display of hina dolls. The district sits a short walk from Kaizuka Station on the Nankai Main Line, with a tourist information point by the station to orient you before you set off.

Q&A
- Can I go inside the Risai annex?
- No. The Risai residence is a private home and is not open to the public. The annex also stands behind the main house, screened from the street. You can appreciate it as part of the preserved temple-town landscape and explore the open machiya museum and Gansenji temple nearby to see comparable interiors.
- What makes the upstairs room unusual?
- It is a Western-style room added around 1924 to an otherwise traditional Japanese merchant compound. It has a tiled fireplace, stained-glass windows, and original light fittings, all hallmarks of the eclectic Taishō-era taste for mixing Japanese and European styles within a single household.
- How is a Registered property different from a National Treasure?
- Registration is a lighter form of protection than designation. National Treasures and Important Cultural Properties are designated and closely supervised by the state. Registered Tangible Cultural Properties, a category created in 1996, cover buildings about fifty years old or older that contribute to the historic landscape, with lighter obligations so owners can keep using them.
- How do I get to the temple town?
- The Kaizuka Jinaichō district is roughly a five-minute walk from Kaizuka Station on the Nankai Main Line, south of central Osaka. A tourist information point sits by the station. The Risai house stands on Kitamachi, near the historic core of the town.
- When is a good time to visit?
- The townscape rewards a walk in any season. For something special, time a visit to mid-March, when several old houses open their interiors for an annual display of hina dolls.
