A Brewer's House with a Chimney Through Its Roof
Wakakoma Shuzo Main House (若駒酒造主屋, also written Wakakoma Shuzō Shuoku or Wakakoma Sake Brewery Main Building) is an early Meiji-period brewery dwelling in the Kogusuri district of Oyama City, Tochigi Prefecture, entered on Japan's national register of tangible cultural properties on 31 July 2007. It stands among rice fields in the northwestern corner of the city, facing south across a narrow irrigation channel that still runs the length of its frontage.
The frame is timber, two storeys, carried under a hipped roof of the form Japanese carpenters call yosemune-zukuri and finished in sangawara pantiles. Entry comes on the long eaves side rather than through a gable end. The Agency for Cultural Affairs records a building area of 333 square metres, with single-storey wings on the east and north sides identified as later additions and one enlargement dated to Shōwa 12 (1937).
The plan splits almost down the middle, and the split is the point. East of centre lie the zashiki, matted rooms where a landowning family received guests and settled accounts. West of centre opens a wide earthen-floored doma that also contained the kamaba, the hearth room where rice was steamed for brewing. Household and workshop met along a single line drawn on the floor.
From the southwest corner a chimney climbs and breaks through the wide sweep of tile. Visitors who have walked the approach from the road describe the characters ワカコマ still faintly readable on its shaft.
Registered Rather Than Designated, and Why That Matters
Japan runs two parallel systems for protecting historic buildings. Designation as an Important Cultural Property or National Treasure applies to a small, rigorously selected group and brings permit requirements and substantial state support. Registration, introduced by the 1996 amendment to the Law for the Protection of Cultural Properties, works differently: owners file notifications rather than seek permissions, and the framework was built to catch the large volume of Meiji-era and later buildings disappearing before anyone assessed them. Wakakoma Shuzo Main House belongs to the second system.
The registration record lists the criterion applied as 造形の規範となっているもの, roughly "a standard of design." Two other Wakakoma buildings entered the register on the same day under registration numbers 09-0163 and 09-0164; the main house holds 09-0162. All three came in the fifty-fifth round of registrations, with the public notice issued on 13 August 2007. Checking the surrounding numbers in the national database shows 09-0161 belonging to the Oyama City Archives stone storehouse and 09-0165 to an unrelated house in the Otome district, which confirms that exactly three structures at this brewery carry the status.
Wakakoma Shuzo itself dates further back than its buildings. The company was founded in Man'en 1 (1860), the last years of Tokugawa rule, and the brewery describes its first head as a merchant from Ōmi province who chose Oyama for its rice and its groundwater. The registration record dates the main house to the early Meiji era, which places the present structure a little after the business it houses. The Agency's database enters the calendar range for that era as 1868 to 1911, a broad span typical of how the register handles buildings without a documented construction date.
What a Visitor Actually Sees
This is a working brewery and a private home, not a museum, and the distinction shapes any visit. Wakakoma publishes no fixed tour schedule or admission fee. Sake enthusiasts who have made the trip describe telephoning ahead and being shown the yard, the old wooden vats, and the tasting counter by the sixth-generation owner-brewer Kashiwase Yukihiro. Arriving unannounced during the winter brewing season is not likely to work. Anyone hoping to go inside should contact the company in advance in Japanese.
From the public road the exterior reads clearly enough on its own. The chimney is the landmark, visible across the fields well before the gate. Photography of the exterior from the roadway raises no issue; photographing interiors or brewing spaces needs the owner's permission, and some equipment areas are off limits for hygiene reasons.
The main house has a second life on television. Scenes for the TBS Sunday-drama JIN, a time-travel series about a modern surgeon stranded in the late Edo period, were filmed here, including the sequence in which the protagonist manufactures penicillin. The signboard for the drama's fictional Jinyūdō clinic has been kept on site, hung above shelves of freshly pressed sake.
The building carries damage as well as history. The 2011 Tōhoku earthquake cracked walls across the compound and stripped part of the chimney's outer surface, and a later storm brought down the roof over one of the central brewing structures. Production continues in the buildings that held.
Getting there takes some patience. Omoigawa Station on the JR Ryōmō Line is the nearest stop, roughly a twenty-minute walk along a road with no pavement in places and no shops near the station. Oyama Station, twelve minutes away on the Shinkansen from Tokyo, is the practical transfer point, and a taxi from there is the easier option for anyone carrying bottles home. Four other sake breweries operate within the city, one of which runs a formal tour and tasting programme, so a day built around Oyama sake does not depend on gaining entry here.
Timing helps too. The traditional Japanese craft of sake brewing was inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity in December 2024, and small family breweries working with wooden vats and hand-pressed bags are exactly what that listing describes.

Q&A
- Can visitors go inside Wakakoma Shuzo Main House, and is there an admission fee?
- There is no published tour programme, no set opening hours, and no admission fee. The building is a private residence and part of an operating brewery. Visitors who have been shown around arranged it by telephoning the company beforehand, in Japanese. The exterior can be seen from the public road at any time.
- How do I reach Wakakoma Shuzo Main House from Tokyo?
- Take the Tōhoku Shinkansen to Oyama Station, about twelve minutes from Ueno. From there transfer to the JR Ryōmō Line for Omoigawa Station, then walk roughly twenty minutes northwest. There are no shops or restaurants near Omoigawa Station, and a taxi from Oyama Station is the simpler choice.
- Why is Wakakoma Shuzo Main House registered rather than designated as an Important Cultural Property?
- Registration is a lighter form of protection created in 1996 for the large number of Meiji-period and later buildings at risk of quiet demolition. Owners notify the authorities of changes instead of applying for permission, which suits buildings still in daily commercial use. The criterion cited for this house is that it represents a standard of design.
- Is Wakakoma Shuzo Main House the building used for filming the drama JIN?
- Yes. The main house and surrounding brewery buildings appeared in the TBS series JIN, and the penicillin-making scenes were shot on the premises. A signboard from the drama's fictional clinic remains on display where sake is sold.
- Can I buy Wakakoma sake at the brewery itself?
- Bottles have been sold from a counter inside the compound, though stock is limited: annual output runs to only a couple of hundred koku, and much of it goes to specialist retailers. Availability at the brewery is not guaranteed, so contact the company first, or look for the Wakakoma label at sake shops in Oyama and Utsunomiya.
