A Japanese Wing Added to a Western House
Hagino Family Residence Zashiki Wing (萩野家住宅座敷棟, Haginoke Jūtaku Zashiki-tō, also written Hagino-ke Jūtaku Zashikitō) is a single-storey timber building of 1915 at Shiomidaichō 1-chōme in Suma Ward, Kobe, Hyōgo Prefecture, entered on Japan's national register of Tangible Cultural Properties on 13 March 2025. It covers 69 square metres and is roofed in pantiles with sheet metal over part of the structure.
The compound it belongs to sits on high ground behind Suma Beach, in the belt of hillside plots that Kobe's merchant families took up once the railway made the coast an easy ride from the city. The oldest building on the site is not this one. A Western wing went up in 1907, weatherboarded and painted pale, with a colonnaded porch and veranda facing south and a diamond-lattice ceiling over the veranda boards. Eight years later the family added a Japanese wing to the north-east of it, and that is the building described here.
Adding a Japanese wing to a Western house, or the reverse, was the standard way of building for well-off Japanese households of the period. The Western rooms took visitors and business; the tatami rooms held the family, the ancestors and the seasonal rituals. What is unusual at Shiomidai is that both wings have survived on the same plot, along with a storehouse, in a ward that lost a great deal in the 1995 earthquake.
Inside the Zashiki: Two Rooms and a Garden
The wing runs north to south under a hipped-and-gabled roof of sangawara pantiles, with a lavatory block extending to the south-east so that the two arms enclose a garden on the south side. The plan is simple: two tatami rooms in sequence, opening into each other when the sliding partitions are drawn back, with a veranda along the south face separating the rooms from the garden.
The southern room carries the formal fittings. There is a tokonoma, the recessed alcove where a hanging scroll and a seasonal arrangement are placed. Beside it sits a biwa-doko, a low shelf named for the lute that was traditionally rested there, and next to that a set of chigai-dana, shelves staggered at two levels rather than aligned. Against the outer wall is a tsuke-shoin, a built-in writing bay projecting into the veranda with a low window above the desk surface. This is the standard vocabulary of the shoin room, and the Agency for Cultural Affairs entry notes that the whole set is present.
The detail that earned the register's attention is the timber. The post at the corner of the alcove, the tokobashira, is a shibori-maruta: a cedar trunk grown against forms so that its surface hardens into vertical ripples, a Kitayama forestry speciality that takes decades to produce. Elsewhere the carpenters used kobutsuki-maruta, logs left with their burls in place. Both are chosen, not shaped. The official description calls the result an elegant piece of work built from carefully selected material, which in the flat register-entry language of the database counts as praise.
Registered in 2025, and Why It Matters
This is a recent entry. The national council recommended the Hagino buildings on 22 November 2024, and registration followed on 13 March 2025 in the 109th round, under numbers 28-0827 for the Western wing, 28-0828 for this zashiki wing and 28-0829 for the storehouse.
The criterion applied to the zashiki wing is worth noting. Japan's register uses several tests, and the commonest is that a building contributes to the historic landscape. This one was registered under a different heading: that it is a model of its type of design. That criterion points at the object rather than at its setting, and it is the reason the alcove fittings and the choice of posts appear in the official description at all.
The third building completes the picture. The storehouse stands at the north-west corner of the plot, a two-storey structure on a cut-stone base with a gable end facing south, its walls finished in white plaster. Above the lintel of the front door, a plasterer worked a relief of waves and a dragon in kote-e, the technique of modelling pictures in lime mortar with a trowel. Craftsmen capable of that kind of work were not commonly employed on a suburban house, and its presence says something about what the family was prepared to spend.
Visiting: Please Read This First
The Hagino compound is a private residence. It is not a museum, it has no opening hours, no admission charge and no visitor entrance, and registration as a Tangible Cultural Property does not create any right of access. The address appears in the national database because the register is a public record, not because the house receives callers.
For anyone who wants to see the buildings, the honest answer is that photographs published by the Agency for Cultural Affairs are the practical route, and its database carries images of the zashiki and lavatory block seen from the south-west. Shiomidaichō itself is roughly ten minutes uphill on foot from Suma Station on the JR Kobe Line or Sanyo-Suma on the Sanyo Electric Railway, and the streets are ordinary residential lanes. If you walk them, walk past. Do not enter the grounds, do not photograph over walls into private gardens, and do not knock.
Suma rewards the trip in other ways. Sumadera, the temple associated with the young warrior Taira no Atsumori, is a short walk from Sumadera Station; the prefectural Suma Rikyū Park occupies the hillside to the east; and the beach below is the reason the hillside filled with houses like this one in the first place. Newly registered properties are sometimes opened for a single day during Kobe's heritage events, so it is worth checking the city's cultural property announcements before assuming the buildings can never be seen.

Q&A
- Can you visit or tour Hagino Family Residence Zashiki Wing?
- No. The Hagino compound is a private home with no public opening, no admission and no visitor entrance. Registration on the national list records the building; it does not open it. Please do not enter the grounds or photograph into the garden. Watch Kobe city cultural property announcements in case of a one-off open day.
- When was Hagino Family Residence Zashiki Wing registered as a cultural property?
- On 13 March 2025, in the 109th round of registrations, under number 28-0828. The national council had recommended the property on 22 November 2024. Three buildings were registered together: the Western wing of 1907, this zashiki wing of 1915, and a storehouse dated between 1912 and 1918.
- What is a zashiki wing, and how does it relate to the Western wing at the Hagino residence?
- A zashiki wing is a detached or semi-detached range of formal tatami rooms. At the Hagino house the Western wing came first, in 1907, and the zashiki wing was built to its north-east in 1915. This pairing of a Western block for guests and business with Japanese rooms for family and ceremony was the normal pattern for prosperous households of the period.
- What are the architectural highlights of Hagino Family Residence Zashiki Wing?
- The southern of its two connected tatami rooms holds a full set of formal fittings: an alcove, a low biwa-doko shelf, staggered chigai-dana shelves and a built-in writing bay. The alcove post is a shibori-maruta, a cedar trunk grown to develop vertical ripples, and other posts are burled logs. A veranda separates the rooms from the enclosed south garden.
- Where is Hagino Family Residence Zashiki Wing, and what is the nearest station?
- Shiomidaichō 1-chōme, Suma Ward, Kobe, on the slope north of Suma Beach. The nearest stations are Suma on the JR Kobe Line and Sanyo-Suma on the Sanyo Electric Railway, roughly ten minutes uphill on foot. Since the house is not open, treat this as orientation rather than an itinerary.
