Ōhamasaki Lighthouse

Ōhamasaki Lighthouse is a maritime navigation structure in Onomichi featuring three towers positioned on a single-story wooden building at the edge of Nabekari Strait. The structure was designed to guide vessels through this important maritime passage using a distinct light signal.

The structure was built in 1894 during the Meiji period as a tidal signal station. Its function gradually expanded to serve broader maritime navigation needs for the region.

The lighthouse holds recognition as a Civil Engineering Heritage site, demonstrating how Japan values its maritime infrastructure from earlier centuries. This status shows how the structure connects to the broader story of coastal development and safety in the region.

The lighthouse is easily accessible from the coastal road in Onomichi and can be viewed from nearby vantage points. Visiting during daylight hours allows you to see the structure and surrounding coastal landscape clearly.

The lighthouse uses a distinctive light signal pattern to guide ships through the waterway, with the beam cycling on and off at regular intervals. This repetitive pattern allows vessels to identify their position when approaching the strait during darkness.
