Toimisaki Lighthouse, Maritime beacon on Cape Toi, Kushima, Japan.

Toimisaki Lighthouse is a white cylindrical tower standing on a 240-metre cliff at the southern tip of the Nichinan Coast Quasi-National Park in Kushima. Its concrete tower is the only part dating from the 1929 construction; the lantern room was rebuilt after wartime bombing and a 1950 typhoon. A staircase inside leads up to the gallery, and an exhibition room beside the tower displays the lighthouse's history and lens materials.

The navigation facility began operations on December 22, 1929, and became essential guidance for ships traveling along the Nichinan coast. The structure dates from a period when maritime navigation depended heavily on such coastal landmarks.

The lighthouse stands at the southern tip of Nichinan Kaigan Quasi-National Park, not a national park. The surrounding area is known for wild horses, and the park's name appears in the lighthouse's setting. The lighthouse is also listed among Japan's 50 Selected Lighthouses.

The lighthouse is open to the public for a fee, and visitors climb to the top; the attached exhibition room displays the original first-order lens and other lighthouse materials. On clear days the view reaches the Uchinoura rocket base and Tanegashima. The site stands on a 240 m cliff at the southern end of the Nichinan Coast Quasi-National Park.

This is the only climbable lighthouse in Kyushu, offering a 270-degree view of the Pacific Ocean from its observation platform. Visitors can see how the coastline stretches in both directions from this elevated vantage point.
