About Yura Kō Outer Breakwater Lighthouse

A red, cylindrical concrete tower with a flared top stands 9 meters tall on a detached breakwater protecting Yura harbor. The structure's light emits a red flash every 5 seconds from a focal height of 16 meters, providing a geographic range of 12.2 nautical miles. Constructed from concrete, the tower's design incorporates a round shape with a flared top. The site is open to visitors, though the tower itself is closed to the public. This lighthouse is situated approximately 0.2 kilometers from the nearest port of Yura, Yamagata.

Why it matters: This lighthouse warns mariners of the detached breakwater it stands on, guiding vessels into the protected waters of Yura harbor. Its red flash serves as a clear signal for local fishing boats and other small craft navigating the harbor entrance.
