About Motonoma Kaikyō Lighthouse
Also known as: Motonoma Kaikyō (Motonoma Strait)
This 12-meter cylindrical concrete tower is painted black with a single red horizontal band. It stands on a reef within the narrow Motonoma Strait, a passage between the Japanese mainland and Sakai Oshima. The lighthouse structure includes a round, single-story concrete equipment room attached to the tower and mounted on a concrete pier. It emits two white flashes every five seconds. While the site is open for visits, the tower itself is closed to the public. The nearest port is Hyugadomari, located 7.7 kilometers away.
Why it matters: The Motonoma Kaikyō lighthouse warns vessels of a reef in the narrow and hazardous Motonoma Strait. Its light guides ships through this constricted passage between the mainland and Sakai Oshima, mitigating risks of grounding and collision.
