About Omodaka Lighthouse
Also known as: Omodaka (Shira Se)
Established in 1903, the Omodaka lighthouse is a 7-meter-tall cylindrical concrete tower situated on a small island about 4 kilometers west of Kōgo Saki. Its light, positioned 18 meters above sea level, emits a white flash every 4 seconds and has a geographic range of 12.7 nautical miles. The lighthouse complex includes a round concrete tower with a gallery. While the island site is open to visitors, the tower itself is closed to the public. The nearest port, also named Omodaka, is 2.4 kilometers away.
Why it matters: The lighthouse is essential for local navigation, specifically alerting mariners to the dangerous rocks situated to its east, which are highlighted by a distinct red sector light.
