Sakata Lighthouse, Maritime lighthouse in Sakata, Yamagata Prefecture, Japan.

Sakata Lighthouse is a white cylindrical tower that stands at the harbor entrance and guides ships into the port with its clear signal. The structure rises prominently above the surrounding area, making it visible from the water and serving as a navigation reference point for vessels.

The first lighthouse, a wooden structure called Hiyoriyama Lighthouse, was lit on 20 October 1895 on the left bank of the Mogami River. It was moved to the right bank in 1923 and rebuilt in concrete in 1958. On 1 April 2000 the third and current light was installed atop the Sakata North Port green-space observation deck.

The lighthouse stands on the observation deck of the Sakata North Port Green Space lookout, and the same building houses the "Minato Monoshiri-kan" exhibit on Sakata Port. The first wooden lighthouse, lit in 1895, was moved to Hiyoriyama Park, where it is kept as a memorial.

The lighthouse sits atop the Sakata North Port Green Space observation deck, whose viewing room overlooks the Sea of Japan and the harbour; a port information display, the Minato Monoshiri-kan, is inside. The site lies in the Takasago district of Sakata, about 20 minutes by taxi from JR Sakata Station.

The lighthouse beam can be seen from far out at sea and remains visible even during adverse weather conditions. This long-range visibility makes it a dependable navigation aid for vessels approaching this section of the Japanese coast.
