The Main Gate of the Former Main Building of the Itsuo

An Edo-Period Gate That Opens onto a Shōwa Villa

Before a visitor reaches Kobayashi Ichizō's reinforced-concrete villa in Ikeda, they pass beneath a gate that is older than the house by more than a century. It stands at the northwest corner of the grounds, a long-house gate of the type called nagayamon, in which rooms flank a central passage. Where the villa behind it speaks the language of the twentieth century, this gate speaks that of the late Edo period, and the short walk between them crosses a hundred and fifty years.

The structure measures 9.9 metres along the front and 3.5 metres in depth, a single-storey timber building roofed in pantiles over a hip-and-gable (irimoya) form. At its centre a doorway 4.2 metres wide carries a pair of hinged leaves, with a smaller wicket door (kuguri-do) set into the wall on either side for everyday passage. The walls are finished in white plaster above a skirt of horizontal boarding, and lattice bay windows with small eaves break the surface. The room on the north served as a guardhouse, while the tatami-floored room on the south was used for the night watch.

The gate is said to have been moved here in 1936, brought from the nagayamon of a village headman's house in the Nose district north of Ikeda. Its timbers, then, had already framed the entrance to a rural estate for generations before Ichizō set them at the threshold of his own.

Why the Gate Was Registered

In August 2009 the gate was entered in the national register of Tangible Cultural Properties under registration number 27-0533, alongside the villa, its wall and two tea houses. Like most of the group it was listed for contributing to the historic character of the national landscape, and its value lies partly in the company it keeps. A gate is rarely the star of a compound, yet here it sets the terms of arrival.

Its history also captures a habit of its age. Wealthy builders of the early twentieth century often gave a new estate the dignity of the past by relocating an older gate to its entrance, and Ichizō followed that practice. The original metal fittings are preserved down to small details, so the doors still carry the hardware they were made with rather than modern replacements. Set against the villa's Spanish-shaped tiles and half-timbering, the gate supplies a note of unbroken tradition at the very point where the property begins.

Documents connect the gate to a village headman's residence, though the exact house is recorded only through local tradition, so it is described as a relocation rather than a certainty. That caution is itself part of the record: the gate is old enough that its earlier life survives more in memory than in paper.

What to Look For on a Visit

Pause under the central doorway before walking through. Look up at the pair of leaves and the wicket doors beside them, and at the metal fittings that hold everything together, small and functional and original. The roof carries the same pantiles you will see across the compound, tying the gate visually to the villa despite the gap in their ages.

Notice, too, the two rooms. The one to the north was where a gatekeeper watched the entrance; the tatami room to the south let a night guard rest without leaving his post. These were working spaces, and they remind you that the gate was not merely decorative but the functioning edge of a large household. Cross beneath it and the villa comes into view, so that the gate does exactly what a good threshold should: it prepares you for what lies within.
