Senami Beach, Beach in Murakami, Japan

Senami Beach stretches roughly one kilometer along the Sea of Japan, offering views of the shoreline and natural surroundings in Niigata Prefecture. The shoreline has gently sloping sections and narrow rocky areas where water meets land.

In 1620, the Murakami domain lord planted a coastal forest to protect houses and fields from wind and sand; this grove still lines the shore. On 3 October 1945, about 20 US warships and transports landed here, and troops stayed until December, using the beach as a supply base because mines still blocked Niigata port. A monument erected in 1995 marks the landing.

The beach takes its name from the Senami onsen district beside it, and the two have shared a shoreline since the hot spring resort grew up next to the bathing spot. The beach is also listed among the Ministry of the Environment's 100 Selected Bathing Beaches (Kaisuiyokujo Hyakusen).

The beach offers free parking for about 360 vehicles nearby, making it convenient to reach by car. The best time to visit is during the summer months when the water is warm enough for swimming.

On 3 October 1945, about twenty US Navy warships and transports landed troops here; residents rushed home and barred their doors. The occupation force stayed until December, using Senami as its base on the Sea of Japan side because mines still littered Niigata harbour. A monument on the beach has marked the landing since 1995.
