Kasamisaki Lighthouse, Maritime beacon at Cape Kasa, Kaga, Japan.

Kasamisaki Lighthouse stands on the cliff of Cape Kasa in Hashidate, Kaga, Ishikawa Prefecture. It is a medium-sized white square tower. The long, flat sandy coast from Kaga toward the Noto Peninsula offers few landmarks, so the lighthouse marks the southwestern end of that shoreline for passing ships and offshore fishing boats.

This beacon was constructed in 1950 to meet growing demands for maritime safety along this coast. Its establishment reflected Japan's expanding shipping activities and the need for improved navigation aids in the region.

The name changed from Hashidate Lighthouse to Kasamisaki Lighthouse in 1966, then to its present form in 1982. The cape sits within the Echizen-Kaga Kaigan Quasi-National Park, and nearby Katano Kamoike is a Ramsar-listed pond for wintering wildfowl.

The site has parking available and a marked walking path that leads to the lighthouse in a short time. The terrain is relatively accessible, making it straightforward to visit on foot.

The lighthouse was renamed twice: in 1966 from Hashidate Lighthouse to Kasamisaki Lighthouse, and in 1982 the characters were changed to the current 加佐岬灯台. In 2010 the incandescent bulb was replaced by an LED, which changed both its intensity and its range.
