How the Estate Supplied Its Own Water
Hisatsune Family Residence Water Tower is a brick tower of 1924 in Kamimiyanaga, Nakatsu City, Oita Prefecture, entered on the national register as a Registered Tangible Cultural Property in 2001.
It rises against the north face of the east storehouse. The plan is a square of about 1.3 metres a side, so the thing reads as a slender column. The walls are slag brick laid a single brick thick. The upper quarter or so is rendered in cement and holds the tank, and a small gabled roof of copper sheet caps the top.
Put a tank up high and gravity does the rest. Before mains water reached the district, that was the only way an estate could distribute its own supply. Hisatsune Family Residence Water Tower is that principle turned into a structure.
Why It Was Registered
Hisatsune Family Residence Water Tower is registered as difficult to reproduce, in the same group as the east storehouse, the west storehouse and the chimney.
Material and technique are half the reason. Raising a slender structure in slag brick a single leaf thick is not something that can be done the same way now. The other half is survival. Domestic water towers go out of use the moment mains water arrives, and once redundant they get demolished. Being equipment rather than architecture, they rarely acquire the status that would protect them.
The Agency for Cultural Affairs calls it one of few surviving clues to domestic conditions in the Taisho era. That a piece of household plant, not a building, was valued in these terms is what defines the place of Hisatsune Family Residence Water Tower on the estate.
What to Look For
The thing to find on Hisatsune Family Residence Water Tower is the line where the finish changes. The lower three quarters or so leaves the slag brick exposed; the upper quarter is rendered. That seam marks the height at which the tank begins inside. The structure explains its own section from the outside.
The cap is copper. A small gabled roof keeps rain and leaf litter out of the tank. Where the patina has come through, a spot of green sits above the red brown of tile and the darkened brick.
Laid a single brick thick means the wall is one brick deep and no more. Carrying a tower only 1.3 metres across up to that height on such a wall puts the whole burden on the accuracy of the joints. This is work that exposes the bricklayer.
The sources do not agree on the height. The structural field of the Agency for Cultural Affairs record gives 7.6 metres; the description on the same page says about 5 metres. The list of cultural properties published by the Nakatsu City Board of Education also gives about 1.3 metres a side and about 5 metres in height, agreeing with the description. The structural field is the odd one out. The table below follows it and its figure of 7.6 metres, and both figures are given here.
Visiting
Because Hisatsune Family Residence Water Tower stands against the north face of the east storehouse, its upper part shows above the boundary wall from the road on the north. The tall narrow profile makes it easy to pick out between roofs and branches. Look towards the eastern end, behind the line of the storage shed and the ondol room.
The grounds cannot be entered, so the brickwork at the base is out of reach. Nothing is advertised that would allow a look inside the tank.
Winter is the better season for finding it. With the leaves down the sightlines open and the outline separates from the background. In summer the trees tend to swallow it.
