The lighthouse uses a large, first-order Fresnel lens, which is among the most powerful configurations used in Japanese maritime history.
It is positioned to guide ships along the Kuroshio Current, a powerful warm western boundary current that flows past the cape.
The lighthouse is recognized as one of the '50 Lighthouses of Japan' selected by the Japan Lighthouse Association.
The cape's unique geological strata feature exposed granite cliffs that have been sculpted by relentless Pacific wave action.
The surrounding landscape contains remnants of indigenous camellia forests that thrive in the mild, humid climate of the cape.
Cape Ashizuri Lighthouse sits at the southernmost tip of Shikoku, overlooking the Pacific Ocean from a 60-meter-high granite cliff. Built in 1914, this white concrete tower is one of Japan's largest lighthouses by lens size. The structure functions as a critical navigational aid for vessels passing through the Kuroshio Current. The area is located within the Ashizuri-Uwakai National Park, characterized by its subtropical vegetation and rough, eroded coastline. A 2-kilometer walking trail, the Ashizuri Peninsula Promenade, connects the lighthouse to nearby coastal rock formations. The site is noted for its high curvature of the horizon, offering a panoramic view of the ocean edge.

Wear sturdy walking shoes to navigate the uneven coastal paths around the cliffside.
Bring binoculars to observe sea life and distant cargo ships navigating the Kuroshik Current.
Prepare for high wind speeds; the cape is famously exposed to ocean gusts.
Attempting to climb down the steep, unmarked cliffs to the water's edge, as current and tide conditions are dangerous.
