About Oragahama Lighthouse

This lighthouse, a white cylindrical concrete tower, stands 12 meters tall and was first lit in 1997. Its light is positioned 41 meters above sea level and emits a single white flash every 8 seconds, visible for over 17 nautical miles. The structure includes a lantern and gallery. Oragahama Lighthouse is situated on a bluff projecting into the sea, approximately 5 kilometers northeast of Tomioka. Following a significant earthquake, the lighthouse went out of service but was restored and resumed operation in April 2013. Access to the site and tower remains closed to the public due to its location within the nuclear disaster exclusion zone.
