About Tamae Kō Lighthouse

This 9.5-meter red concrete lighthouse stands on a rock at the western entrance to the Hashimoto River. The cylindrical tower is accompanied by a square, single-story equipment shelter. Its light emits a red flash every 8 seconds, visible for 11.9 nautical miles. The lighthouse is situated on the east side of Hagi City, marking the river's confluence with the sea. The site is open to visitors, but the tower itself remains closed. A white spotlight also directs its beam toward the breakwater on the opposite side of the harbor.

Why it matters: This lighthouse is essential for safe navigation into and out of the Hashimoto River, warning vessels away from the western entrance point and guiding them through the channel.
