Stone Wall of the Former Shigetomi Shimazu Family Villa

Twenty-Four Metres of Stone and Brick

The Stone Wall of the Former Shigetomi Shimazu Family Villa (旧重富島津家別邸石塀, Kyū Shigetomi Shimazu-ke Bettei Ishibei) is a boundary wall of welded tuff and brick in Shimizu-chō, Kagoshima City, raised in the late Meiji period between 1898 and 1912 and entered on Japan's register of Tangible Cultural Properties on 25 April 2014.

It begins at the southeast corner of the audience chamber of the main house and runs south, turning as it goes. Total length is 24 metres. The Agency for Cultural Affairs classifies it as stone and brick construction with a tiled top, and counts it as a single structure in its own right rather than as an appendage to the residence.

That last point matters. Walls seldom earn separate entries in the national register. This one did because of what it is made of and how the two materials are stacked.

The lower part is welded tuff, cut into blocks and laid in nunozumi, regular horizontal courses with continuous bed joints. Welded tuff is the stone of Kagoshima. The pyroclastic flows that built the plateaus around Kinkō Bay left thick beds of ash compacted by their own heat into workable rock, soft enough to saw and hard enough to last, and quarries across the prefecture supplied it for warehouses, embankments, tunnels and garden walls. A Satsuma mason of the 1900s would have handled it since apprenticeship.

On top of the stone sits brickwork, laid in English bond. Alternate courses show only long faces and only short ends, which ties the two skins of the wall together and gives the surface its stepped rhythm of headers and stretchers. Brick arrived in Japan with Western engineering in the second half of the nineteenth century, and English bond became the standard for load-bearing work. Above the brick runs a roof of sangawara, the pantiles used on ordinary Japanese buildings.

Three layers, three eras of building culture, one wall. Nothing about the combination is decorative in intent, yet the effect is unmistakable: warm red masonry banded between grey volcanic stone below and grey tile above.

Why It Was Registered

Japan's registration system, in place since 1996, protects buildings and structures roughly fifty years old or older through notification rather than permit, on the reasoning that a structure kept in use survives better than one sealed off. The Stone Wall of the Former Shigetomi Shimazu Family Villa holds registration number 46-0111 and was taken up in the 77th round, with notification and registration both dated 25 April 2014. The main house alongside it carries number 46-0110 and went through the same day.

The criterion applied was contribution to the historical landscape of the country, and the official description explains why in a single observation: the wall bends according to the rise and fall of the ground and changes height as it goes, so that a heavy form produces a varied streetscape. A wall built to a constant height on a level base would read as a barrier. This one reads as terrain.

The Kagoshima Prefectural Board of Education adds a point of contrast that assessors of registered properties tend to look for. Exposed red brick set against a Japanese-style timber residence marks the building culture of the modern period, and here the two sit within a few metres of each other. The prefecture also records that the wall, like the main house, is said to have been moved to this site from what is now Kimotsuki Town around 1906. That account comes down as tradition rather than documentation, and the national database gives only the broad late-Meiji date range.

Kagoshima lost most of its central districts to air raids in 1945, and Meiji-period masonry of this quality is scarce in the city. Surviving with its original coping and its full run intact adds to the case.

Looking at It Properly

Walk the length rather than photographing it head-on. The changes in height happen at the turns, and each turn presents a fresh combination: taller stone and shallow brick where the ground drops away, the reverse where it rises. The mason had to reset the coursing at every step, and the joints show where those decisions were made.

Look at the stone surface closely. Welded tuff takes tool marks well and weathers into a soft grey with lichen in the damp months, and blocks cut from different beds carry different densities of the pumice fragments trapped when the flow settled. Some faces are almost uniform; others are freckled.

The brickwork rewards a second look for a different reason. Count along a course and the pattern of English bond becomes visible: one course all stretchers, the next all headers, with a narrow closer brick at each end to keep the vertical joints staggered. Japanese brick of this period is often slightly irregular in size and colour because it was fired in kilns with uneven heat, and the variation is easier to see on a low wall at eye level than on a large building.

Then step back and take in the relationship the wall holds with the main house. It starts at the corner of the audience chamber, the most formal room on the site, and screens the southern approach while framing views of the garden beyond. The grounds run to roughly 4,000 tsubo with a waterfall and planting that shifts through the seasons, and Kinkō Bay with Sakurajima sits below.

Access needs planning. The wall stands on private commercial property operated as Manor House Shimazu Shigetomisō, and there is no admission ticket for the grounds. Visitors normally come through a booking at the French restaurant AUTOMNE, which takes telephone reservations for lunch between 11:30 and 14:30 and dinner between 18:00 and 21:30 and closes Tuesdays and Wednesdays outside public holidays, or at Café du Marié, open 11:30 to 16:00 on Mondays, Thursdays and Fridays. Weddings and private functions occupy the site on other dates. A taxi runs about five minutes from JR Kagoshima Station, fifteen from the east exit of Kagoshima-Chūō Station and ten from Tenmonkan. Photographing the wall and garden for personal use is generally accepted; check with staff on the day, particularly when an event is running.
