Former Yoshihara Family Residence Service Gate and Brick Wall

The Everyday Gate of a Headman's Estate

The Service Gate and Brick Wall of the Former Yoshihara Family Residence (旧吉原家住宅通用門及び煉瓦塀, Kyū-Yoshiharake Jūtaku Tsūyōmon oyobi Rengabei) is a gate of the late Edo period with an attached brick wall added in the late Taishō period, standing at Aza-Nakanofunatsu, Ōaza-Obo in Ōkawa City, Fukuoka Prefecture, and entered on Japan's national register of Tangible Cultural Properties for buildings on 2 May 2017.

The estate behind it belonged to the Yoshihara family, who held the post of bettō, the administrative head of the town of Obo under the Yanagawa domain, and later served as ōjōya over the Kamachi district. Their main house, built in 1825, was designated an Important Cultural Property in December 1999. The gate and wall registered here are the parts that face the street.

Two openings pierce the south side of the estate, and they were never equals. At the centre is the Onarimon, the ceremonial gate, newly built in 1838 when the household prepared to lodge shogunal inspectors; it is covered by the same designation that protects the main house. Toward the east corner is the tsūyōmon, the gate used every other day of the year. Brick walling runs east and west from it, with the ceremonial gate set partway along the western stretch.

Measured plainly: the gate is timber-framed, roofed with pantiles, and 4.6 metres across the front. The brick wall runs 31 metres in total and carries a tiled roof of its own.

An Unusual Gate and an Unexpected Material

The gate is a munamon, the simplest of the formal gate types: two posts, a beam, a ridge above. What sets it apart is what hangs in the opening. Instead of the hinged double doors that a gate of this class almost always carries, it is fitted with two sliding panels, each running to one side. The Agency for Cultural Affairs describes the arrangement as a rare form, and it is the reason this modest side entrance was recorded at all.

The wall introduces a second surprise. It is not built of the familiar red clay brick of Meiji and Taishō industry but of slag brick, made with metallurgical slag, which fires to a greyish brown quite unlike the usual colour. Laid up in the closing years of Taishō, roughly the 1920s, it wrapped a Bunsei-era estate in a material that had not existed when the main house went up a century earlier. The roof of pantiles laid along its top keeps the whole street frontage reading as one composition rather than as an old house with a modern fence in front of it.

Registration cited the criterion for structures contributing to the historical landscape of the country. That criterion fits the case exactly. Neither the gate nor the wall would carry an article on its own; together they are the face the estate turns to Obo, and the reason the street still looks as it does.

Seeing It in the Streets of Obo

Approach on foot along the old highway and look at the two gates in sequence before going in. The Onarimon is raised, formal and centred, built to be walked through once in a generation by someone important. The service gate sits off to the side, lower, plainer, and it is the one that saw daily traffic: deliveries, servants, the household itself. Reading them against each other tells you more about how a headman's house worked than any floor plan.

Then look closely at the brick. Slag brick weathers differently from clay, and in flat light the wall reads almost as stone. Where the wall meets the older gateposts, the join between two centuries of building is visible at eye level.

Obo repays the walk beyond this one address. The town sat on the border between the Yanagawa and Kurume domains, and a boundary marker survives as a city-designated historic site. Several neighbouring properties, among them the Yoshihara family branch house, the Egashira residence and the buildings of Jōfukuji, are registered in their own right. Ōkawa itself is known nationally for woodwork and joinery, and that craft tradition shows in the interiors here.

The main house is open to visitors from 9:00 to 17:00, with last admission at 16:30, and admission is free. It closes on Mondays, or the following day when a Monday falls on a public holiday, and over the New Year period. The gate and wall stand on the street frontage, so they can be seen and photographed from outside at any hour without entering the site. Guides are usually on hand indoors and are generous with time; craft workshops and tea are offered on some days for a separate fee.
