About Jodo Lighthouse

Also known as: Jodo (Jo Do)

The Jodo Lighthouse stands as a 16-meter cylindrical concrete tower, painted white, on the northeastern tip of Jodo island. Established in 1917, its light operates from a focal height of 55 meters. The lighthouse emits a single white flash every four seconds, visible for 19.4 nautical miles. This structure replaced an earlier, shorter tower. The station is situated off the southeastern tip of Mireuk Island, near Tongyeong-si. Access to the lighthouse is exclusively by boat.

Why it matters: This lighthouse marks the northeastern tip of Jodo island, guiding vessels navigating the waters north of the Ogokdo light and helping prevent groundings.
