About Kasayama Saki Lighthouse

Completed in 1966, this concrete lighthouse stands on Fukue Shima, an island forming the southernmost part of Nagasaki Prefecture. The cylindrical white tower, measuring 11 meters in height, rises from a square equipment room. Its light emits a single white flash every 6 seconds, with a focal height of 19 meters. A continuous white spotlight is also directed towards a nearby reef, specifically marking this submerged hazard. The lighthouse site is accessible to the public, though the tower itself remains closed.

Why it matters: This lighthouse warns vessels of the southernmost point of Fukue Shima and illuminates a dangerous nearby reef, contributing to maritime safety in the region.
