Amaharashi Coast Beach sits at the mouth of the Amaharashi River in Takaoka City, on the western shore of Toyama Bay in Toyama Prefecture. The shore is fine white sand backed by a grove of black pines, and the water is clear enough on calm summer days to see the sandy bottom a few meters out. The beach curves in a shallow, gently sloping arc rather than a tight cove, giving it moderate exposure to bay winds and light surf that stays manageable for wading and casual swimming. Just offshore, the small pine-topped islet of Onnaiwa Rock is the defining visual feature, framed on clear winter days by the snow-capped Tateyama mountain range across the water, a combination that has made the spot one of Japan's officially ranked 100 Best Beaches and a favorite for both sunrise and sunset photography. The overall atmosphere is family-oriented rather than a party scene: local households come for shallow-water wading, sandcastle building, and picnicking under the pines, and the beach quiets down outside the July-August swimming season. Roadside Station Amaharashi, immediately adjacent, supplies free parking, public restrooms, and food stalls selling local seafood and shaved ice, though there are no permanent sun loungers or beach-side cafes on the sand itself and no posted lifeguard hours, so swimmers should treat the beach as unsupervised. Access is straightforward: Amaharashi Station on the JR Himi Line is a five-minute walk from the shore, and the roadside station's free lot serves drivers arriving via the coastal road from Takaoka or Toyama City.
