About Gunchu Kō Lighthouse
Also known as: Guntyu
The Gunchu Kō lighthouse is a square tapered stone tower measuring 7.5 meters high, topped with a traditional box lantern. Its focal height is 13 meters above sea level. Constructed from unpainted stone, the structure is designed to be durable against coastal conditions. It emits a single red flash every 7 seconds, visible for 11.3 nautical miles. The lighthouse is located 1.2 kilometers from the nearest port of Iyo, within the Gunchu Kō sea region. The site is open to the public, but the tower itself is closed.
Why it matters: This lighthouse was essential for the safe navigation of vessels entering and leaving the port of Gunchu Kō, preventing groundings in the approaches. Its unique architectural features, combining a stone tower with a traditional box lantern, create a distinctive visual landmark.
