An Annex Built for a Museum That Had Outgrown Itself
The New Building of the Abashiri City Museum (網走市立郷土博物館新館, Abashiri Shiritsu Kyōdo Hakubutsukan Shinkan) is a 1961 annex in Katsura-chō, Abashiri City, Hokkaido, attached to the east side of the museum's 1936 main block and listed as a Registered Tangible Cultural Property (Structure) by the national government on 5 December 2019.
The reason it exists is ordinary enough. A museum that opened in 1936 with roughly 3,000 objects had, by the late 1950s, run short of room.
Much of the pressure came from the ground. The Moyoro shell mound at the mouth of the Abashiri River had been dug by one man, the barber and amateur archaeologist Yonemura Kioe, since 1913. After the war, university teams from Tokyo and Hokkaido joined the work, and organised excavation campaigns from 1947 onward brought human remains, pottery, stone tools and worked bone out of the sand in quantities a single small building could not absorb. Abashiri City had taken over operation of the museum in April 1948 and now had to house what its own soil kept producing.
The annex went up in November 1961, timed to the museum's twenty-fifth anniversary. The city went back to the architect who had designed the original.
The Same Architect, Twenty-Five Years Later
Tanoue Yoshiya (1899 to 1991) had built the 1936 block as a symmetrical, tower-topped composition with geometric panels worked into the plastered facade, the vocabulary he used through his prewar decade. By 1961 he was in his sixties, and his work had changed. The Agency for Cultural Affairs entry for the New Building says so directly: the elevation takes the older building into account, while the cut-ins and modelled surfaces of the wall show the manner Tanoue arrived at after the war.
That sentence is the reason both buildings carry registration. Two works by one architect, twenty-five years apart, standing in contact on a single hillside, let a visitor read a career rather than a moment. Abashiri put them forward together on exactly that argument, and both were registered on 5 December 2019 under the criterion of being a model of design.
The published structure differs from the older building in kind, not only in style. Official records give the New Building as timber and reinforced concrete, two storeys above ground with one below, roofed in metal sheet, with a footprint of 138 square metres. The plan is a rectangle. The roof runs in a single pitch, against the tower-topped arrangement next door. A basement level is unusual in this part of Hokkaido, where frost depth complicates excavation, and for a museum accumulating boxes of excavated material it solves a practical problem.
One note for anyone comparing sources. The descriptive text on the national database calls the New Building a two-storey timber structure with a basement, while the structural field in the same record specifies timber and reinforced concrete over two above-ground floors and one below. The structural field is the formal entry and is followed here.
What to Look For
Walk the site rather than the entrance. The interest of the New Building lies in how it meets the older one, and that is visible from outside without paying admission.
Stand back on the east side. The 1936 block insists on symmetry; the annex does not. Its mass is a plain rectangle, its roof a single slope, and its wall surface is worked with recesses that read as carving rather than as applied ornament. Tanoue kept the horizontal lines of the elevation in conversation with the older building, so the two do not clash, but the language has shifted from pattern to modelling. Prewar Tanoue decorates a surface. Postwar Tanoue cuts into it.
The joint between the two is worth a minute on its own. Additions of this period often ignore what they attach to. This one does not, and the restraint is the point.
Inside, visitors move through the museum as a single institution rather than as two buildings. The permanent displays cover the natural history of the Okhotsk region on the lower level and human history above, with Moyoro material at the centre of the archaeological rooms. The museum also mounts special exhibitions on natural history and historical themes, reported at roughly two a year, which bring out holdings that are not normally on view. Anyone specifically interested in seeing the interior of the annex should ask at the desk, since gallery use varies with the exhibition schedule.
Opening hours run 9:00 to 17:00 from Tuesday through Sunday, with a 16:00 close from November through April. The museum is shut on Mondays, on national holidays, and from 29 December to 3 January. Admission covers the whole site at 120 yen for adults and 60 yen for elementary and junior high school students, dropping to 96 and 48 yen for groups of twenty or more. There are five parking spaces, and the walk from JR Abashiri Station takes about fifteen minutes.
Photography follows a city guideline in force since 13 May 2026. Stills and video for personal keeping are permitted within posted limits; any other use requires an enquiry to the museum beforehand, and video for non-personal purposes is not allowed. The exterior, which is where most of the architectural interest sits, presents no difficulty.
Time of year changes the visit. Snow lies on the hill from roughly December into April, and the single-pitch roof and cut wall surfaces read differently under it than they do against summer green. The shorter winter hours are worth checking before setting out.

Q&A
- What is the Abashiri City Museum New Building, and when was it built?
- It is the 1961 annex attached to the east side of the Abashiri City Museum, completed in November of that year to mark the museum's twenty-fifth anniversary. The museum had opened in 1936 and needed more space, largely because postwar excavation at the Moyoro shell mound was producing more material than the original building could hold. It became a Registered Tangible Cultural Property on 5 December 2019.
- Can visitors go inside the Abashiri City Museum New Building?
- The museum operates as one institution and ordinary admission covers the site, so the annex is not a separate ticket. Which galleries are in use at any given time depends on the exhibition schedule, so asking at the front desk on arrival is the reliable way to find out what is open. The exterior, where most of the architectural interest lies, can be seen at any time from the grounds.
- How is the Abashiri City Museum New Building different architecturally from the 1936 main block?
- The main block is symmetrical, carries a tower with a rounded red roof, and has geometric figures worked into plastered facade panels. The annex is a rectangle under a single-pitch roof, built of timber and reinforced concrete over two floors with a basement, and its wall surfaces are shaped by recesses rather than applied pattern. Tanoue Yoshiya designed both, and the second shows the manner he developed after the war.
- Why were the Abashiri City Museum New Building and the Main Building registered on the same day?
- Because the case for each depends on the other. Abashiri argued that having two works by Tanoue Yoshiya twenty-five years apart, in physical contact on one site, makes the shift in his design thinking legible in a way neither building would achieve alone. Both were registered on 5 December 2019 under the criterion of being a model of design, as registration numbers 01-0156 and 01-0157.
- When is the best time to visit the Abashiri City Museum New Building, and how do you get there?
- The museum sits on a hill in Katsura-chō, about fifteen minutes on foot from JR Abashiri Station, with five parking spaces on site. Hours are 9:00 to 17:00 Tuesday through Sunday, shortened to 16:00 between November and April, with closures on Mondays, national holidays and 29 December to 3 January. Summer gives longer hours and easier walking on the slope; winter gives the annex against snow, which suits its plain geometry.
