Owada Family Rental Store

A Shopfront Built for Tenants

The Owada Family Rental Store (大和田家貸店舗, Owada-ke Kashitenpo) is a two-storey timber commercial building in the Kokufu district of Ishioka City, Ibaraki Prefecture, put up around 1930 and entered on the national list as a Registered Tangible Cultural Property on 19 September 2003.

What sets it apart from the other historic shopfronts on the same street is who it was built for. Ishioka City describes it as premises raised from the outset to be rented out, and notes how few buildings of that kind survive. The Owada family were not the shopkeepers here. They owned the frontage, and the plan follows from that fact: three column forms with carved capitals rise across the face of the building, and the middle one divides the ground floor into two separate units, each of them lettable to a different trade.

The Agency for Cultural Affairs records a timber frame of two storeys under a steel-sheet roof, with a building area of 138 square metres. The frontage runs 5 Ken and the depth 10 and a half ken, so the shell is more than twice as deep as it is wide. That proportion is the standard Machiya arrangement of a Japanese merchant street, where street frontage was the expensive commodity and land was taken in depth instead.

Ishioka Rebuilt Itself in Mortar and Sheet Metal

In 1929 a fire swept the centre of Ishioka. The town that replaced the one that burned is the town visitors photograph today, because the shopkeepers rebuilt in a manner that had arrived from Tokyo after the Great Kanto Earthquake: kanban-kenchiku, literally signboard architecture.

Ishioka City sets out the type in flat terms. A two-storey timber shop and dwelling has its street face raised vertically and finished in mortar, copper sheet or tile, and Western-derived ornament is applied to that flat surface. The city then adds an observation worth carrying to the site. The decoration seldom follows Greek or Roman precedent correctly, and that departure is precisely what gives provincial signboard architecture its character. Unnamed local carpenters were working from pictures of Western buildings using the joinery skills they already had, and the result is a popular architecture with no foreign original.

The Owada Family Rental Store belongs to this wave of rebuilding, dated by the Agency for Cultural Affairs to around 1930. Its registration in 2003 was made under the criterion covering buildings that could not easily be reproduced. The registration number is 08-0103, granted in the 38th round, with the gazette notice following on 17 October 2003.

A landlord's building is a useful thing for a historian. A shopkeeper builds for one trade; a landlord builds for whoever turns up next. The doubled shop front, the plain interior depth, the ornament concentrated entirely on the public face: all of it is a calculation about rent.

Reading the Face of the Owada Family Rental Store

Start with the three columns. They are not structural columns in the European sense but column forms, applied to the flat front, each finished with a capital that Ishioka City describes as Corinthian in spirit. Between them the wall carries the shop openings. The central column is the working one: it marks the party line between the two rentable halves.

Then look at the left-hand column, and look twice. Its upper section does not sit directly above its lower section. The two are deliberately offset, a slip in the vertical line that no classical order would permit and that no one standing across the street can quite ignore.

Under the eaves runs a band of small blocks cut to resemble the ends of rafters, a toothed course that does the work of a dentil cornice. Above the parapet, three chimney-like projections stand up from the roof. They vent nothing. The Agency for Cultural Affairs, which is not given to strong adjectives, calls the combination of these features a singular piece of design.

Walk to the corner and look down the side wall. Behind the raised front there is an ordinary timber townhouse with an ordinary roof, and the flank makes no promises the front cannot keep. Seeing both at once is the quickest way to understand what signboard architecture actually is.

Visiting the Owada Family Rental Store

The Owada Family Rental Store still earns its keep. Ishioka City lists the property under a double name, Owada Family Rental Store (Kissaten Shiki), because a coffee shop occupies the ground floor. The building has therefore never become a museum piece, which is the reason the frontage has stayed in repair.

The exterior can be seen from the public street at any hour, with no admission charge and no restriction on photographing it from the pavement. Going inside is a different matter: that depends entirely on the business trading there, so check its opening days before making a special trip. The upper floor is not shown to visitors.

From JR Ishioka Station on the Joban Line the walk is about 10 minutes westward, towards Nakamachi-dori, the old main street that carries part of National Route 355. Ishioka City counted 19 registered buildings within the municipality as of 2010, several of them within a few minutes of this one on the same street, so the Owada Family Rental Store is best seen as one frontage in a sequence rather than as an isolated monument. Opening details for the tenant business were last checked on 6 September 2026.
