The Face a Merchant House Shows the Street
Matsugaya Entrance Wing (松賀屋玄関棟, Matsugaya Genkan-tō) is a single-storey timber structure in Nio, Mitoyo City, Kagawa Prefecture, built in the late Meiji period between 1898 and 1912 and entered on Japan's national register of Tangible Cultural Properties on 31 October 2022. It fronts the road on the eastern edge of the Matsugaya compound, the walled property of the Shiota family, salt and shipping merchants who used the trade name Matsugaya.
Every house in a merchant town performs. The building where business is done faces outward and is dressed accordingly; the family's own rooms sit behind, out of sight. This wing is the outward-facing half of that arrangement, and its registration criterion says so: it was registered as a building contributing to the historic character of the landscape, unlike the main house behind it, which was registered as a model of design.
The footprint is modest, about 82 square metres. Its work is done at the boundary rather than in the volume behind it.
Reading the Frontage
The roof is irimoya, hipped-and-gabled, tiled, and set hirairi, meaning the entrance sits on the long eaves side rather than under a gable. That orientation gives the building a wide, level presence along the road instead of a pointed one.
Under the projecting geya canopy at the front, a latticed bay window called a degōshi sits north of the doorway. Lattice of this kind let people inside watch the street without being watched in return, and in shop buildings it also displayed goods to passers-by.
Above, a low loft storey known as a tsushi nikai runs across the front. The register lists the building as single-storey because a tsushi is a half-height space under the roof rather than a full floor, used for storage and for keeping the interior cool. Its wall is finished in nezumi-shikkui, plaster tinted a soft grey with pine soot, and pierced by a mushiko-mado: a small window with thick vertical plaster bars, named for its resemblance to an insect cage.
Grey plaster, black lattice, heavy tile. The palette is restrained, and it was expensive.
One further detail rewards a look up at the eaves beside the entrance. The downpipe there was formed in the shape of Ebisu, the deity associated with fishing and with commercial fortune, an appropriate patron for a house that made its money from the sea.
How the Building Is Entered
Two routes run through the wing, one for goods and staff, one for guests.
The earth-floored doma at the south end passes through to a courtyard, and from the courtyard into the doma of the main house. That is the working line, the one carrying deliveries, water and the daily traffic of a household that employed clerks and kitchen staff.
The raised-floor route is the formal one. A visitor stepped up into the toritsugi, the receiving space where a caller was met and assessed, then moved through a tatami room and on into the main house. North of the toritsugi is a tea room.
That tea room says a good deal about how the family understood hospitality. Placing it here, close to the entrance rather than deep in the private quarters, meant a guest could be received over a bowl of tea without entering the household proper. Business and ceremony met at the threshold.
The Agency for Cultural Affairs summarises the building's value in one phrase: it composes the frontage of a merchant house. The wing exists to make the compound legible from the street.
Seeing It in Context
Nio was a port before it was a salt town. Medieval records place the area within estates held by major shrines and temples with ties to the capital, and by the Edo period thousand-koku coastal freighters were calling here, with merchant houses lining the lanes. Buildings from the Edo, Meiji, Taishō and Shōwa eras still stand in the old quarter, which is why a walk through Nio is worth more than a single stop.
The wing can be appreciated from the public road at any time, and this matters, because the compound is private and interior access depends on the calendar. The managing body, a general incorporated association named after the house, holds free open days on an irregular schedule announced through its website and social media. Paid rental of the rooms, formerly offered at 5,000 yen plus tax for three hours, has been suspended since February 2026 while maintenance is carried out.
Immediately south of the wing stands the compound's registered storehouse, and the pair reads best together: the entrance dressed for receiving people, the storehouse dressed for holding goods, both facing the same street.
Getting there is straightforward by car. The site lies about 15 minutes from the Sanuki-Toyonaka interchange on the Takamatsu Expressway, with five free parking spaces. Using public transport takes planning: JR Yosan Line trains stop at Takuma Station, from which Mitoyo City community buses on the Nio Line run Monday to Saturday excluding public holidays at a flat 100 yen, though departures are few. A taxi from Takuma takes 12 to 15 minutes.

Q&A
- Can I see Matsugaya Entrance Wing without going inside the compound?
- Yes. The wing faces the road on the eastern side of the property, so the frontage with its lattice bay, grey plaster loft and insect-cage window is visible from the public street at any time. Interior access is limited to open days and events organised by the managing association.
- When was Matsugaya Entrance Wing built, and how is it protected?
- Dating places it in the late Meiji period, between 1898 and 1912, which makes it older than the 1916 main house behind. It was entered on the national register of Tangible Cultural Properties on 31 October 2022 under number 37-0467, for contributing to the historic character of the landscape.
- Does Matsugaya Entrance Wing really have a tea room?
- It does. The tea room sits north of the toritsugi, the receiving space just inside the raised floor, allowing guests to be entertained near the entrance rather than in the family's private rooms. It is documented in the Agency for Cultural Affairs record for the building.
- Is Matsugaya Entrance Wing a separate cultural property from the main house?
- Yes. Three structures on the compound hold separate registrations made on the same day: the entrance wing (37-0467), the main house (37-0466) and the storehouse (37-0468). The main house was registered as a model of design, the other two for their contribution to the landscape.
- How do I reach Matsugaya Entrance Wing by public transport?
- Take the JR Yosan Line to Takuma Station, then a Mitoyo City community bus on the Nio Line into central Nio. Buses run Monday to Saturday except public holidays for a flat 100 yen but are infrequent, so check the timetable. A taxi from Takuma Station takes about 12 to 15 minutes.
