About Kan Saki Lighthouse

Also known as: Kan Saki (Kanzaki, Ko Saki)

This lighthouse, operational since 1894, is Tsushima's oldest light station. It features a white, octagonal cylindrical concrete tower, 11 meters tall, built on the seaward side of a 1-story concrete keeper's house. The light is situated 61 meters above sea level and emits a white flash every 15 seconds, visible for 20.2 nautical miles. The tower rises from a steep and remote promontory at the southeastern tip of Tsushima island. Reaching this isolated station involves navigating a challenging landscape.

Why it matters: Its strategic placement on a remote promontory guides vessels around a critical headland, underscoring its continued relevance for maritime safety in this part of Japan.
