Hiwasa Kō South Breakwater Lighthouse

Fl Green 3s🇯🇵Minami, JPOperational

Also known as: #Hiwasa Kō South Breakwater

This navigational aid guides mariners approaching the port of Hiwasa. The original structure, an 8.5-meter white concrete post with an equipment shelter, marked the harbor entrance for an unspecified time. Between 2010 and 2013, it was replaced by a modern beacon. This current light emits a green flash every three seconds from a focal height of 13 meters and has a geographic range of 11.3 nautical miles. Its location on the north end of the detached outer breakwater makes it accessible only by boat. While the tower is closed to visitors, the site itself can be reached by sea.

Why it matters: This light is essential for vessels navigating the waters around Hiwasa, marking the northern extremity of the detached outer breakwater and ensuring safe entry and exit from the port.

Structure: The Hiwasa Kō South Breakwater light guides mariners approaching the port of Hiwasa, situated at the northern tip of its detached outer breakwater. Originally, this navigational aid featured an 8.5-meter concrete post, painted white, which was integrated with a square, single-story concrete equipment shelter. This structure served the local maritime community for an unspecified period, marking the crucial entrance to the harbor. However, between 2010 and 2013, the original light was decommissioned and replaced. A smaller, more modern beacon now occupies its place, emitting a green flash every three seconds from a focal plane of 13 meters. This active light continues its vital role, though its site is only accessible by boat, reflecting its offshore location. While the tower itself remains closed to the public, the surrounding site is open for those who can reach it, offering a glimpse of this functional aid to navigation.
