A Fireproof Vault at the Northwest Corner
At the northwest corner of the Yamakawa compound in Obama, Fukui Prefecture, a two-story storehouse stands with its gable end turned to the north and south. This is the dozo, the thick-walled fireproof storehouse of a well-to-do household. It measures about 6.8 metres along the ridge and 5.4 metres across, roofed in a gable of pantile, and covers some 47 square metres. Along the south face a lean-to eave reaches out to form a covered forespace, the kura-mae, where goods could be handled under shelter.
The point of a building like this is protection. Its earthen walls, built up thick and finished hard, were meant to shut out fire and damp, and to guard whatever a family most wanted to keep safe.
Thick Walls, Tall Boards and Iron Doors
The storehouse was registered as a Tangible Cultural Property in 2008, under the standard for structures that contribute to the historic landscape. Registration is Japan's lighter conservation category, below the designation held by Important Cultural Properties, and here it protects a working outbuilding rather than a showpiece.
The construction is the interest. The outer walls are finished in white plaster, with vertical boarding carried high up the face to shield the earthen core from rain. Windows are cut into the north gable end and the east face, each fitted with a single-leaf iron door and a small pent roof, so that the openings can be sealed against fire. A dozo is built the way it is for a reason: the mass of earth moderates heat and holds off flame, the tall boarding and the iron shutters defend the vulnerable points. The official record describes the storehouse as one element making up the whole layout of the residence, and it holds down the northwest corner of the plan with quiet solidity.
The Household's Strongroom, Now Part of a Museum
In a family of the Yamakawa's standing, former senior retainers of the Obama domain who moved into banking after the Meiji Restoration, a storehouse was where heirlooms, documents and valuables were kept out of reach of fire and theft. The residence became the childhood home of the poet Yamakawa Tomiko (1879–1909), and the whole compound, storehouse included, opened as the Yamakawa Tomiko Memorial Museum in 2007.
Where the main house and detached room speak of formal reception and quiet living, the storehouse speaks of keeping and guarding, the practical spine of a household. Seen alongside the gates and the garden, it completes the picture of how such a residence actually worked. One note for visitors: the museum is temporarily closed from April 2026, with reopening planned for around July, while pest treatment and repairs are carried out.
