Ikarashi Cospo is the heart of Sea of Japan surfing, producing consistent waves when Siberian winter storms sweep across from the northwest. The beach features white sand, dunes, and gorgeous views of Sado Island, with mellow waves that work for all levels. The water is shallow enough to touch bottom, making it ideal for beginners, while winter swells can produce fun right-handers across multiple peaks. The local community is welcoming, without the localism found at more famous breaks.

The Ikarashi Cospo Beach profile favors the recorded tide range, ideally between 0.2m and 1.2m on the local tide chart. Compare this preference with the forecast tide and local conditions before choosing a session.
The Ikarashi Cospo Beach profile uses wind from E (90°) as its preferred direction, with an offshore range of 50° to 130°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.
The Ikarashi Cospo Beach scoring profile favors swell from WNW (260° to 340°), a swell-height range of 0.8m to 2.5m, and a reference period of 9s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
