About Mano Wan Breakwater Lighthouse
This 9.5-meter white concrete post light is attached to a 1-story concrete equipment shelter. It stands at the east end of a detached breakwater that shelters ports on the west side of Mano Bay, an embayment on the south side of Sado Shima. The light emits a green flash every six seconds. The site is open to the public, but the tower is closed. It serves vessels navigating the protected waters of the bay, near Futami, Niigata.
Why it matters: The light provides critical guidance for vessels navigating the sheltered waters behind the long detached breakwater, marking its eastern end and ensuring safe access to the bay's harbors.
