About Murozumi Kō Lighthouse

The Murozumi Kō lighthouse, built in 1949, stands 9 meters tall. It is a white concrete post attached to a 1-story concrete equipment room. This structure is located at the end of a breakwater extending from a hook-shaped spit that shelters Murozumi Harbor. The light emits an occulting white flash every 6 seconds, visible for 11 nautical miles. The site is open to the public, though the tower itself is closed. Its nearest port is Murozumi, just 0.3 kilometers away.

Why it matters: This lighthouse is essential for the safe entry and exit of vessels into Murozumi Harbor, guiding them around the spit into the sheltered waters.
