About Tsuken Shima Lighthouse
Also known as: Tuken
Established in 1976, the Tsuken Shima lighthouse is a 14-meter tall cylindrical concrete tower located on Tsuken Island, east of Okinawa Honto. Its focal height reaches 51 meters, providing a geographic range of 18.8 nautical miles. The structure features a gallery and emits a single white flash every 4 seconds. While the lighthouse site is accessible to the public, the tower itself is closed to entry, maintaining its operational status. It guides vessels through the waters east of Okinawa.
Why it matters: This lighthouse is important for the safe navigation of local vessels, particularly ferries and fishing boats, operating in the coastal shipping lanes of the Ryukyu Islands.
