About Mimitsu Kō Lighthouse

Also known as: Mimitsu Kō (Tatsugami Bae)

Mimitsu Kō Lighthouse, built in 1934, is an octagonal concrete tower standing 17 meters tall, with its base colored gray and the rest of the structure painted white. It is situated on a skerry at the end of the south breakwater protecting the port of Mimitsu. The lighthouse emits a white flash every 4 seconds, visible for 13.8 nautical miles. Its unique octagonal pyramidal design is topped with a lantern and gallery, with the overall structure mounted on a 1-story concrete base. The site is open to visitors, but the tower itself is closed to the public. The nearest port, Mimitsu, is 1 kilometer away.

Why it matters: This lighthouse is essential for mariners navigating the approach to Mimitsu port, warning them of the skerry and breakwater. Its distinctive octagonal pyramidal design with a 'hat-like' lantern roof makes it a notable architectural feature.
