About Tsuiyama Kō Lighthouse

Also known as: Tsuiyama Kō (Sarugazō Training Wall)

This red, cylindrical concrete tower stands 10 meters tall, marking the end of a longitudinal pier in Tsuiyama harbor. Its focal plane is 12 meters above sea level, casting a red light with an eclipse characteristic every 6 seconds. The lighthouse's construction date is not recorded, but it has been in operation for an unknown period. A significant issue has emerged with the tower developing a severe lean, which has been observed to be increasing. The site surrounding the lighthouse is accessible, but the tower itself is closed to the public.

Why it matters: The lighthouse is indispensable for local vessels, clearly marking the end of the pier within Tsuiyama harbor to prevent accidents. Its most notable characteristic is the severe and seemingly worsening lean of its concrete tower.
