The Nagayamon Gate: A Farmhouse Threshold With a Wartime Past

The first structure a visitor meets at Sōshidō is the gate. A nagayamon, or long-house gate, it dates to the late Edo period, sometime between 1830 and 1868, and forms the front face of what was once a silk-farming homestead. The two-story timber gate is now roofed in copper sheet, though it began life under cedar bark. On the east side of the front, a projecting lattice window catches the eye, and small openings light the tsushi loft above.

At about 63 square meters, the gate is larger than its name suggests, with rooms built into the wings on either side of the central passage. That arrangement is what makes the building worth a second look: a nagayamon was never only a gate, and this one carried a household's history through some difficult years.

Why the Gate Was Registered

The Agency for Cultural Affairs registered the nagayamon as a tangible cultural property on 27 February 2023, under registration number 13-0482 and the criterion for buildings that contribute to the historic landscape of the country. It joined the main house, the Western annex, and the storehouse under the listing Former Residence of Yoshikawa Eiji (Sōshidō).

The gate earns that recognition by holding the shape of a Meiji-era farm entrance in a region where such structures have grown rare. Its lattice, its loft windows, and its long low profile set the tone for the whole property, and they remain legible from the road as the threshold to a working farmstead.

The Wings and Their History

The two wing rooms tell different stories. The west wing keeps an earthen floor, while the east wing is boarded. During the war the gate gave shelter, with the rooms used to house people who had evacuated from the cities. After the war Yoshikawa Eiji put the space to his own use, keeping books and storing belongings in the wings while he lived and wrote in the main house nearby.

Pause under the central passage before moving on to the rest of the grounds. The gate frames the garden and the buildings beyond, and the wear on its timbers carries the memory of the wartime years when a writer's family and their neighbors crowded into this corner of Ome.
