About Ōhara Kō Detached Breakwater Lighthouse
This 12-meter cylindrical concrete post light stands at the end of a detached breakwater in Ōhara harbor, Chiba Prefecture, Japan. Attached to the post is a 1-story square equipment room, also constructed of white concrete. The structure guides vessels with a green light that flashes every six seconds. Its focal height reaches 14 meters, providing a geographic range of 11.6 nautical miles. The site is open to visitors by boat, but the tower itself is closed to the public, maintaining its operational status.
Why it matters: The light warns mariners of the detached breakwater's termination, preventing collisions and facilitating safe passage into Ōhara harbor, supporting local fishing and commercial activities.
