The Rice Store and the Library

On the eastern side of the gate stands the No. 2 storehouse. Its interior is divided almost evenly: a rice store to the east and a book store (shoko) to the west, each with its own doorway on the north side. Built in the Taishō period, between 1912 and 1925, it belongs with its neighbours to a phase of rebuilding the compound's front early in the twentieth century.

A Fire-Resistant Store

This is a true dozō, a fire-resistant storehouse with thick mud-plastered walls, registered in 2005 for its part in the frontage. The gabled roof is tiled in two grades, formal pantile to the south and lighter tile to the north. Along the lower south wall runs vertical boarding, with windows set above.

Set beside the gate, the storehouse squares up the front of the residence and gives the eastern approach its solid, shuttered line.

Why a Family Kept a Library

The book store is the telling half. A household that set aside a plastered, fire-proof room for documents was a household that kept records, and the Kotani did. The family that later founded this museum had generations of collecting behind it.

The founder, Kotani Michiakira (1909–1991), a local historian, drew on exactly that habit of keeping when he opened the collection to the public in 1971. The storehouse that once guarded rice and paper now stands within the museum those papers helped bring into being.
