About Otona Se Lighthouse
The Otona Se lighthouse was established in 1951 on a concrete pier positioned on a reef 2.5 kilometers east of Sao Saki. This cylindrical concrete tower, measuring 16 meters high, is painted black with a red horizontal band. Its light emits two white flashes every five seconds from a focal height of 20 meters, with a geographic range of 13.2 nautical miles. The site is open to visitors, though the tower itself is closed to the public. The nearest port, Shukunoura, is 4.8 kilometers away.
Why it matters: This lighthouse warns vessels of a submerged reef east of Sao Saki, serving as a critical guide for maritime traffic navigating the coastal waters.
