Ishibashi Family Residence Room

A Late-Meiji Wing Holding the Street Line

The Mukō-zashiki of the Ishibashi Residence (石橋家住宅向座敷, Ishibashi-ke Jūtaku Mukō-zashiki) stands at 834 Shinmachi in the Hirata district of Izumo City, Shimane Prefecture, dates from the late Meiji period, and was entered in the national Register of Tangible Cultural Properties on April 28, 2010. It occupies the southern side of the plot, directly on the street, and is the only one of the three registered buildings here with two full storeys.

The name needs unpacking for anyone reading it in translation. A zashiki is a formal matted room used for receiving guests. Mukō means facing or opposite, so a mukō-zashiki is a reception wing set across from, or forward of, the main living quarters. The word describes a position rather than a style. Visitors should keep it distinct from the oku-zashiki, the inner reception room deeper inside the compound, which local guides discuss as a separate space with its own history.

The registration record gives a building area of 79 square metres, timber construction of two storeys, and a hipped-and-gabled roof, irimoya-zukuri, laid with sangawara pantiles. Pent roofs run along the east and west sides. The building sits on a footing of coursed stone, and its walls are finished in white lime plaster laid over the frame, with horizontal boarding protecting the lower portion. Wide lattice windows are set into the east elevation on both floors.

Three Buildings, Three Generations

The mukō-zashiki carries register number 32-0119, the last of the three Ishibashi entries, and was processed in the 67th round of registrations with the gazette notice published on May 20, 2010. All three came in under the criterion covering structures that contribute to the historic landscape of Japan.

Read the three dates in order and a family history emerges. The main house belongs to the closing years of the Edo period. The tea room went up in the middle Meiji era. This wing came last, in late Meiji. A landowning family that had spent the Edo period accumulating standing on the Izumo plain kept building through the transition into the modern state, first adding a space for leisure at the back, then a formal reception wing at the front. The registration record notes that the mukō-zashiki forms the traditional street scene together with the main house, which is the clearest statement in the official documentation that the two were assessed as a pair.

That pairing is what a passerby actually sees. Hirata prospered as a market town supplied by waterways from the western shore of Lake Shinji, and became the collection point for Unshū momen, the cotton produced across the plain. The route through Shinmachi, Kataharamachi and Miyanomachi is now promoted as the Momen Kaidō, the Cotton Road, and its character comes from a continuous run of plastered gable-entry frontages. A gap in that run would break the effect. The mukō-zashiki fills the southern half of the Ishibashi frontage and keeps the wall of the street unbroken.

What the Elevation Tells You

Compare this building with the main house next to it and the difference in period announces itself. The main house presents a gable to the street with pent roofs stretched to either side, an Edo merchant solution to a narrow plot. The mukō-zashiki is squarer, two storeys of equal presence, roofed in irimoya, a form that carries more formality than a plain gable.

The stone footing is worth a look at ground level. Coursed masonry laid in even beds, nunoishi-zumi, indicates a builder working to a level line rather than fitting rough stone as it came, and it lifts the timber clear of ground damp. Above it, the boarded skirt, shitami-ita, takes the splash and weathering that would otherwise pit the plaster; the white lime above stays clean, and the two-tone elevation that results is characteristic of Meiji-period townhouse work across the San'in region.

The lattice windows repay attention. They are described in the registration record as broad, and they appear on both floors of the east face. Width matters in a reception wing: the room behind them was meant for entertaining, and a wide lattice admits considerably more light than the tight screens of a shop front while preserving privacy from the street. Look at the lattice pattern itself, since the Izumo type combines long and short members in a repeating group, a rhythm visible from the pavement.

Access is through the Momen Kaidō Communication Center at 841 Hirata-chō, which sells admission to the residence and provides the guide. The center opens 9:00 to 17:00 and closes on Tuesdays, shifting to the following weekday when a holiday falls on Tuesday. Guided admission is 1,000 yen per person, or 500 yen each for three or more, and the tour lasts twenty to thirty minutes. Guiding is delivered in Japanese, with interpreters bookable in advance on 0853-62-2631. Unshū-Hirata Station on the Ichibata Electric Railway Kita-Matsue Line is about ten minutes on foot. Interior access varies with the room and the day, so anyone with a specific interest in this wing should say so when booking. The exterior can be studied at any hour from the street, and the late afternoon light on the east elevation is the moment to catch the boarding and the plaster in the same frame.
