稚內市役所, Municipal government building in Wakkanai, Japan

Wakkanai City Hall is the municipal government building of Wakkanai, Hokkaido, and the northernmost city hall under Japanese administration. A new reinforced-concrete main building was completed in June 2025 and opened on 14 October 2025: four floors above ground with a rooftop tower, a total floor area of 6,837.68 m² on a 5,254.50 m² site, and 37 parking spaces. It replaced the 1967 seven-storey building at Chūō 3-13-15; the address is Chūō 3-2-1.

The old city hall was completed on 31 August 1967, a seven-storey reinforced-concrete block with a tower room at 3-13-15 Chuo, Wakkanai. It replaced earlier offices of the city, which had become a municipality in 1949. Judged vulnerable to collapse in a major earthquake, it was replaced by a new four-storey hall completed in June 2025 and opened on 14 October 2025 at 3-2-1 Chuo.

The city hall is Japan's northernmost municipal office under Japanese administration, a fact tied to Wakkanai's position at the top of Hokkaido. It keeps two branch offices, Sōya and Numakawa, serving the wider city. The main building moved to a new four-storey reinforced-concrete hall in October 2025, replacing the 1967 structure.

The building provides access to municipal services including resident registration, tax administration, and city planning. Visitors should be prepared for cold weather conditions during winter months when the area experiences heavy snow and extremely low temperatures.

This building operates in Japan's northernmost city, managing administrative services under extreme winter conditions with temperatures dropping below minus 10 degrees Celsius. Its location shapes daily operations and makes the infrastructure a practical example of adapting to harsh climate.
