Abashiri Drift Ice Cruise — Frozen Sea of Okhotsk

Every winter (late January to late March), drift ice (流氷, ryuhyo) from the Russian Far East floats south through the Sea of Okhotsk and reaches Abashiri's coastline, transforming the sea into a white frozen landscape. The ice floes, some meters thick, create an otherworldly seascape of jagged white sheets, turquoise cracks, and ice cliffs. Abashiri's icebreaker ships (Aurora and Aurora II) cruise through the ice, cracking and pushing floes aside with a thunderous crunch.

The drift ice phenomenon is rare globally — Abashiri is one of the southernmost drift ice locations in the Northern Hemisphere. The ice brings cold-water marine life (Okhotsk seals, sea eagles) and creates unique ecosystems. The cruise is weather-dependent, and some years have minimal ice (climate change is reducing ice coverage), making each sighting feel more precious.
