Wakkanai Breakwater Dome, Breakwater structure in Wakkanai, Japan.
The Wakkanai Breakwater extends 427 meters with 70 concrete pillars supporting a curved corridor standing 13.6 meters tall along the northern harbor point.
Built between 1931 and 1936 by engineer Minoru Tsuchiya, the structure protected maritime routes connecting Japan to Sakhalin Island during the prewar period.
The architectural design combines Roman-style arches with Japanese engineering principles, earning recognition as both a Hokkaido Heritage and Civil Engineering Heritage site.
Located five minutes from JR Wakkanai Station, the covered walkway shields pedestrians from strong winds and waves while providing access to the harbor area.
The continuous semicircular arcade features thick concrete columns with 8-meter spacing, creating patterns of light and shadow across the promenade floor throughout the day.
