The lighthouse on the end of the South Breakwater for the port of Otaru, Hokkaido, Japan, taken in May 1974 (recent photos on the internet show little or no change since then).
Height 14 m. Characteristics: two green flashes every 6 seconds. Position 43.19883°N, 141.02416°E.
The light (and breakwater) does not appear on this site's map. It does appear on Google maps (but no breakwater) but is misnamed “Otaru Port Jetty Lighthouse”
