About Akaguri Saki Lighthouse

Akaguri Saki Lighthouse, built in 1967, is a cylindrical concrete tower standing 11 meters tall with a focal height of 23 meters. It features red and white horizontal bands and emits a single red flash every 4 seconds. The lighthouse is located on a small island just off the tip of the Nokogiri Saki peninsula. This peninsula has a hook shape that points southeastward, directing vessels into Kohama Bay. The site is open to the public, though the tower itself is closed.

Why it matters: This lighthouse is essential for guiding ships safely into Kohama Bay and away from the Nokogiri Saki peninsula's hook. Its distinctive hourglass shape and red and white bands make it a recognizable landmark on this coastal route.
