Momoyama Waterworks, Ube

The Momoyama Waterworks (桃山の水道施設) at Momoyama in Kogushi, Ube City, Yamaguchi Prefecture, date from 1924, and two of their structures, the water metering room and the entrance to the No. 1 reservoir inspection gallery, were registered as Registered Tangible Cultural Properties on November 5, 1997 (Agency for Cultural Affairs). Both are owned by Ube City.

The Agency says the works were built as part of the Okinoyama colliery and later served the townspeople; on a hill overlooking the town, they are widely loved as a symbol of the modernisation of daily life.

The Two Structures

The metering room is a small octagonal brick building among hillside houses, known locally as the "hexagon hall"; it was first crowned with an eight-sided pyramid roof (Agency for Cultural Affairs).

The gallery entrance is a concrete doorway into the reservoir's inspection gallery, with pilasters and a pointed arch (Agency for Cultural Affairs). In brick and in concrete, the two recall the Taisho waterworks of a coal-mining town. Each structure is described on its own page.
