Twenty-Five Metres of Stone Facing the Mikuma River
The Stone Wall and Brick Fence of the Yamada Family Residence (山田家住宅石垣及び煉瓦塀, Yamada-ke Jūtaku Ishigaki oyobi Rengabei) is a riverside retaining wall and boundary fence at Kuma 1-214-1 in the city of Hita, Ōita Prefecture, dated by the Agency for Cultural Affairs to 1921 and 1953, and entered on Japan's register of Tangible Cultural Properties on 23 October 2008.
The wall runs 25 metres east to west along the bank of the Mikuma River at the rear of the Yamada plot. It is not a straight line. At the mid-point it pushes out towards the water, and a flight of stone steps descends beside it to the river's edge. The masonry is river cobble laid in mortared courses, the technique called neri-zumi, and the height is around three metres.
Above the stonework sits the brick fence: 26 metres long, one metre high, laid in stretcher bond so that only the long faces of the bricks show. Where the steps drop through the line of the fence, a pair of iron gates hangs across the opening, opening outwards from the centre.
The Agency's description makes a point of the colour. Against the grey of the cobbles and the green of the water, the fired brick reads warm, and it is that band of red running along the top of the bank that the register singles out as the wall's contribution to the river scene.
Built for a River That Rises
The Mikuma is the river formed where the Ōyama and Kusu meet in the Hita basin, and downstream it becomes the Chikugo, the largest river system in Kyūshū. Anyone who has built on its bank has built against the possibility of it coming over the top.
The two dates the Agency records are worth reading together. The earlier one, 1921, falls in the Taishō era, when fired brick had become cheap and widely available in provincial Japan. The Yamada storehouse behind the wall carries the same 1921 date and is described in the national database as a structure that records the history of disaster at this site. The later date, 1953, is the year the Mikuma broke its banks in the flooding that struck northern Kyūshū between 25 and 29 June, remembered as the Shōwa 28 West Japan Flood. A disaster archive compiled at Ōita University records that the Mikuma's overflow carried away the Kameyama, Tokuse and Ishii bridges and cut central Hita off. More than a thousand people died across the affected region.
The register lists the wall under the criterion for structures contributing to the historic landscape of the nation, the same criterion applied to the well and the storehouse on this plot. Four Yamada structures were registered together in the 61st round, announced on 10 November 2008: the main house of 1816, the storehouse, the well, and this wall, which carries registration number 44-0163.
The steps complicate any reading of it as purely defensive. A wall meant only to hold water back would not be pierced for a stairway down to the river. Hita's households drew on the Mikuma for washing, for fishing and for the boat traffic that once moved goods along the Chikugo system, and the stairway with its iron gates is the point where those uses were let through a barrier otherwise built to exclude the water.
Where to Stand
This is the one part of the Yamada property a visitor can properly look at. The main house presents its 22 metre frontage to the street, but the well and storehouse sit on private ground with no public access, and no opening arrangement has been announced for any of the four structures. The riverside wall, by contrast, faces outwards.
The best view is from the water. Pleasure boats operate on the Mikuma through the warmer months, launched from the hot-spring inns that line the Kuma bank, and they pass directly below the wall. From boat level the three metres of cobble read at full height and the brick course sits against the sky.
From land, work along the riverside path and look for the projection at the centre of the run, where the wall steps out towards the current. Then find the iron gates. They are small and easy to miss, set into the gap in the brick where the stairway comes through, and their hinges are the detail that tells you the stair was in regular use.
Photography from public ground is unrestricted, but the plot behind the wall is a private residence and should be left alone. Hita Station on the Kyūdai Main Line is about 1.5 kilometres north, roughly a twenty minute walk. The Kuma district repays a slower circuit: the Reimeikan community centre of 1916 and the registered Gotō Family Residence are both close by, and the Mameda preservation district lies a further two kilometres north.
