About Ōtsuchi Kō Lighthouse
Also known as: Ōtsuchi Kō (Horai Shima)
A round, concrete tower painted red marks Ōtsuchi Kō. This cylindrical structure, standing 7.5 meters tall, emits an isophase red light on a 6-second cycle from a focal height of 11 meters. The lighthouse is situated on an islet accessible by a pier, approximately 0.6 km from the nearest port of Otsuchi. The original light was established in 1953 but was destroyed by a tsunami. A new lighthouse was built in 2012, featuring a distinctive hourglass shape.
Why it matters: The rebuilding of this lighthouse after its destruction by a tsunami highlights its significant role in ensuring safe navigation for vessels entering and departing Otsuchi Port, serving as a symbol of community recovery.
