Concrete, 1930, and an Earthquake in Its First Autumn
The Former Mishima Weather Station Office (旧三島測候所庁舎, Kyū Mishima Sokkōjo Chōsha) is a reinforced concrete building at Higashihonchō in Mishima City, Shizuoka Prefecture, completed in 1930 and entered on Japan's national register of Tangible Cultural Properties on 15 May 2007. It is single-storey with a two-storey central section, covers a building footprint of 267 square metres, and is owned by Mishima City.
The building had been standing for a matter of months when it was tested. On the morning of 26 November 1930, a magnitude 7.3 earthquake struck beneath the Tanna basin in northern Izu. Mishima recorded shaking of intensity 6, the second-highest level on the scale then in use. Mishima Station on the railway collapsed. Thousands of houses across the region came down. Mishima City records that the new reinforced concrete weather station office escaped the damage.
Mishima's building stock today reflects that. The city's own account of its registered properties notes that a great many buildings went up in the late Taishō and early Shōwa years, replacing what the 1923 Kantō earthquake and the 1930 North Izu earthquake had destroyed. This office belongs to the leading edge of that rebuilding, and it was made of the material that had just proved itself.
Registered for Its Design, Not Its Setting
Japan's register admits buildings over fifty years old under one of three criteria: contribution to the historic landscape of the country, setting a standard of design, or being difficult to reproduce. The overwhelming majority come in under the first.
This one did not. The Former Mishima Weather Station Office was registered as a building that sets a standard of design, which among registered properties in Shizuoka is comparatively uncommon and is the single most useful fact for deciding what to look at.
Understand what the building was for. A prefectural weather station of 1930 was an instrument shelter with desks in it. Observers needed light, ventilation and a stable platform, and the architecture that housed such work was expected to be plain to the point of anonymity. Mishima City's description makes the point directly: decorative intent of this quality is rare in a building type where utility and function normally decide everything.
What to Look For on the Facade
The building faces west, roughly one kilometre south of Mishima Taisha shrine. Approach it from the front and the composition reads immediately: a symmetrical elevation with the central section raised to two storeys and single-storey wings to either side. Tall, narrow vertical windows run around all four faces, a modernist rhythm applied without ornament.
The interest is in two places where the architect broke that discipline.
First, the window sill on the second floor of the front elevation bows outward in a semicircle. A sill is a functional edge; curving it serves nothing except the eye, and it catches shadow differently through the day. Second, above the entrance sits a kushigata ranma, a transom with the shallow segmental profile of a comb's back, filled with a metal grille and stained glass. Coloured glass over the door of a government meteorological office is not what the building type calls for.
Neither gesture is large. Together they are why the building was registered under the design criterion rather than the landscape one, and they are what a visitor should stop and look at from the pavement.
Visiting: Check Before You Go
This section needs a clear warning at the top. The building has been closed to visitors.
Mishima City reopened the former weather station on 1 April 2009 as the Eco Center, a base for environmental education displaying instruments from the station's working years alongside material on Mount Fuji and the local environment. Admission was free and four parking spaces were available. Mishima City then suspended use of the building for an emergency structural inspection, describing the suspension as continuing for the time being, and Shizuoka Prefecture's environmental learning portal still lists the facility under a suspended-use heading.
No reopening date has been published. Anyone planning a visit should contact the Environmental Policy Division at Mishima City Hall first, or check the city website, rather than travelling on the assumption that the interior is accessible. The exterior remains visible from the street, and since the facade is the point, a closed building is less of a loss here than it would be elsewhere.
Access is straightforward. The site is a seven-minute walk from Mishima Futsukamachi Station on the Izuhakone Railway Sunzu Line, one stop from Mishima Station, which is served by the Tōkaidō Shinkansen. Mishima Taisha, the Shizuoka Prefecture Rakuju-en park and the Mishima City Museum of Local History sit within easy walking distance, and Mishima has eight other registered buildings within the same compact centre.
One discrepancy worth recording. The national database describes the structure as single-storey with a partial second storey, while Mishima City's summary table lists it as two-storey. The national database is the primary source, and its wording matches the symmetrical raised-centre composition visible on site.

Q&A
- Can you go inside the Former Mishima Weather Station Office (Mishima Eco Center)?
- Not at present. Mishima City suspended use of the building for an emergency structural inspection and has not published a reopening date, and Shizuoka Prefecture's environmental learning portal lists it as suspended. Contact the Environmental Policy Division at Mishima City Hall or check the city website before travelling. The exterior can be seen from the street at any time.
- How do you get to the Former Mishima Weather Station Office?
- It is about a seven-minute walk from Mishima Futsukamachi Station on the Izuhakone Railway Sunzu Line, one stop from Mishima Station on the Tōkaidō Shinkansen. The site lies roughly one kilometre south of Mishima Taisha shrine, and four parking spaces were available when the building was open.
- Did the Former Mishima Weather Station Office survive the 1930 North Izu earthquake?
- Yes. The building was completed in 1930 and the magnitude 7.3 North Izu earthquake struck on 26 November of that same year, registering intensity 6 in Mishima. Mishima City records that the reinforced concrete office escaped the damage that destroyed buildings across the area, including Mishima Station.
- Why was the Former Mishima Weather Station Office registered as a cultural property?
- It was registered on 15 May 2007 under the criterion of setting a standard of design, rather than the more common criterion of contributing to the historic landscape. Mishima City notes that this level of decorative intent is unusual in a building type where utility and function normally govern the design.
- What architectural details should you look for at the Former Mishima Weather Station Office?
- Look at the symmetrical west-facing elevation with its raised two-storey centre and tall narrow windows on all four sides, then at two departures from that plainness: the second-floor window sill on the front, which projects in a semicircle, and the comb-shaped transom above the entrance, filled with a metal grille and stained glass.
