About Miyanoura Breakwater Lighthouse

This white, cylindrical concrete lighthouse stands 8.5 meters tall and is situated at the extremity of a detached breakwater. A square, single-story concrete equipment room supports the post.

It is located at Miyanoura, a small port about 5 km north of Toi Misaki in Kushima.

Why it matters: This light marks the end of the detached breakwater, guiding local fishing vessels and other small craft safely into and out of Miyanoura port.
