About Hyūga No Se Lighthouse

Also known as: Hyūga No Se (Hyugano Se)

Hyūga No Se is a 19-meter-tall cylindrical concrete tower located on a reef near the entrance to Tonoura harbor in Nichinan, Miyazaki Prefecture. Its distinctive green structure rises 22 meters above the water, marking the reef for vessels. The lighthouse emits a single green flash every 8 seconds, visible for 13.6 nautical miles. Constructed from concrete, the round tower stands 1.2 kilometers from the nearest port. While the site is accessible to visitors, the tower itself is closed to the public.

Why it matters: This lighthouse is essential for the safe passage of ships entering and exiting Tonoura harbor, specifically warning them away from the dangerous reef upon which it is built. Its entirely green structure and light characteristic make it a distinctive and easily identifiable aid to navigation in these coastal waters.
