Seals and eagles on an Abashiri drift ice cruise
You board for the ice, and the ice decides how much of a show you get. On a full day the ship pushes through white plates as far as you can see, and on a thin one you look at scattered floes on dark water. This guide covers where the ice comes from and what the open deck shows you. It also covers the wildlife you might spot and the places on land where you get closer to the ice than any ship allows.
Where the ice comes from
Drift ice, ryuhyo in Japanese, is sea ice born in the cold northern reaches of the Sea of Okhotsk. Much of it is thought to begin off the mouth of the Amur River, where the river pours fresher water into the sea, and that water freezes more readily than full-strength seawater. Wind and currents then carry the floes south over several weeks until they press against the Hokkaido coast.
That makes this shore one of the southernmost places in the Northern Hemisphere where sea ice reaches land. It is the reason people travel in the coldest weeks of the year to Abashiri, a small city that most visitors to Japan never hear of. None of it runs on a timetable. The ice usually arrives at some point in late January and lingers through February, but the wind decides where it sits on a given morning, and the best time to see the drift ice weighs the weeks with the best odds.
What the deck shows you
The Aurora boards at Roadside Station Ryuhyo-kaido Abashiri and spends about an hour at sea. Rather than slicing a clean line, its hull is designed to climb onto the floes and press them apart with sheer weight. On a good day you feel a dull shudder through the hull as a plate gives way, then hear the grinding along the sides as broken pieces scrape past and turn over.
From the rail you look down on flat white plates pushed hard against each other, with gray slush packed into the gaps. Between them run open leads of dark water where the pack has pulled apart, and the ship often uses them before it shoves into the next sheet. Toward the horizon the ice can look like a frozen field, broken by ridges where plates have piled up.
On a thin day the picture is different. You may see scattered floes on a gray-blue sea, or open water with a white line far off. The ship still goes out on those days, and the hour becomes a coastal cruise with the snowy shore behind you. Our page on days without ice explains what each tour does then.
The cabins are heated, and most people drift in and out. The open decks are where you see the hull meet the ice, and the wind there is sharp, so read what to wear on the icebreaker before you pack.
Eagles and seals, on a lucky day
Two kinds of eagle spend the winter on this coast. The Steller's sea eagle is the big one, dark brown with white shoulders and a heavy yellow bill. The white-tailed eagle is a little smaller and plainer, with the pale tail its name promises. Both sit on the ice watching for fish, and both look larger than you expect once you find one in binoculars.
Spotted seals haul out onto floes to rest. From a distance they look like gray commas on the white, and they rarely let a ship come near.
None of this is guaranteed, and the listings do not pretend otherwise. JUN Travel's page mentions sea eagles and seals "if you are lucky", which is the right frame. A day with plenty of ice close to shore gives better odds than a day of open water. Binoculars help more than anything else you can bring, because the animals seldom sit near the hull, and a phone camera turns a distant eagle into a dark speck.
Standing on the ice in Shari
A ship keeps you above the ice. Club Tourism's two days from Sapporo add a chance to stand on it. On day 1 the coach stops in Shari, east of Abashiri on the road toward the Shiretoko Peninsula, for a 40-minute drift ice touch experience led by a local expert.
The expert speaks Japanese, and the listing says so plainly, so go for the feeling of the ice under your boots rather than a long talk in English. The listing gives no more detail than that, and neither will we. Do not walk out onto shore ice on your own anywhere on this coast; plates shift and cracks open without warning.
Stand on the ice, then sail through it
From ~$430 per person, Club Tourism's two-day trip from Sapporo puts the touch experience in Shari on day 1 and the Aurora on day 2, with a night at a Shiretoko hotel in between. Lunch on the first day is yours to buy.
Mt Tento and the ice museum
The Okhotsk Ryuhyo Museum stands on Mt Tento above the city. Its best-known room is kept at −15 °C (5 °F) and holds real drift ice, and tanks there often have clione on show, the small see-through sea snails nicknamed sea angels (Clione limacina). An observation deck looks out over the Okhotsk coast, so on a clear day you can judge how much ice sits offshore before you board.
JUN Travel's private day includes the museum, and Club Tourism stops at the Mt Tento viewpoint for 30 minutes. On the H.I.S. trip the museum is the fallback if the cruise is cancelled. Our guide to the Prison Museum and the rest of Abashiri covers the other stops in town.
Kitahama Station by the sea
Kitahama is a small station on the JR line east of Abashiri, set right beside the Sea of Okhotsk. When the ice is in, the frozen sea lies right beside the platform, and a train pulling past a white shore makes a photo you will not get from the ship. On the morning of day 2 Club Tourism stops here between Oshinkoshin Falls and the cruise.
Another ship, another view
Abashiri is not the only port with an icebreaker for visitors. Up the coast in Monbetsu, the Garinko boats work differently, drilling into the ice with screws on the bow instead of pressing it down like the Aurora. A two-day Garinko trip from Sapporo, from ~$427, goes there. The catch is that it puts you on a different ship in a different town, and the listing has no reviews yet. Aurora or Garinko lays out how the two compare.
For the ice room and the cruise in one unhurried day, see our page on private days, which covers JUN Travel's day at ~$2,082 per group.
