Japan’s pelagic birding calendar is more tightly structured than almost any other destination on Earth. The Short-tailed Albatross cruise to Torishima runs only in spring. Hokkaido’s drift ice brings Sea Eagles to the coast for just eight weeks in winter. The Rhinoceros Auklet colony at Teuri Island peaks in a window that ends before summer begins. Miss the window and you miss the bird.
Understanding Japan’s seasonal rhythms is essential for planning a productive trip. Here’s a breakdown of what to expect in each season across Hokkaido, the Izu Islands, and the open Pacific routes.
Winter (January to March): Drift Ice Eagles and Hokkaido Seabirds
Winter is the season for Hokkaido’s most dramatic wildlife encounter. Each January, seasonal drift ice arrives from the Sea of Okhotsk and fills the Nemuro Strait along the Shiretoko Peninsula. With the ice comes one of the most extraordinary bird spectacles in Asia: up to 700 Steller’s Sea Eagles — the world’s heaviest eagle — gathered on ice floes alongside White-tailed Eagles, with Spectacled Guillemots, Long-tailed Ducks, and Harlequin Ducks in the open water leads between them.
The Rausu Drift Ice & Bird Watching Cruise runs from late January through mid-March, with multiple daily departures including a sunrise option. This is the most reliable place in the world to see Steller’s Sea Eagle — the same birds return to the same ice each year — and the relatively sheltered conditions of the strait make it more accessible than open-ocean pelagics.
At the tip of the Nemuro Peninsula, the Ochiishi Nature Cruise runs a complementary winter programme from January through March, targeting Short-tailed Albatrosses offshore alongside Blakiston’s Fish Owl territory, sea ducks in the coastal waters, and Steller’s Sea Lions on the offshore islands.
The Izu Islands ferry route from Tokyo remains productive for albatrosses throughout winter. Short-tailed, Black-footed, and Laysan Albatrosses are all possible on the overnight crossing from late autumn through May. Japanese Murrelets, a highly restricted-range species, are visible in winter off Miyake-jima from the ferry rail.
Target species: Winter
- Steller’s Sea Eagle and White-tailed Eagle: late January to mid-March, Rausu
- Short-tailed Albatross: January to March, offshore Ochiishi; October to May, Izu ferry
- Japanese Murrelet: November to March, offshore Miyake-jima (Izu ferry)
- Spectacled Guillemot: year-round Hokkaido coast, peak winter
- Long-tailed Duck, Harlequin Duck: November to March, Hokkaido inshore waters
Spring (April to May): Short-tailed Albatross at Its Breeding Colony
Spring is the priority season for the single most sought-after bird in Japanese pelagic birding. The Torishima Short-tailed Albatross Cruise — the only expedition that circumnavigates Torishima (Bird Island), 580 km south of Tokyo — runs exclusively in April and May. This is the sole opportunity to observe Short-tailed Albatross as breeding adults and juveniles at the colony slopes, with expert commentary from researchers who have monitored the birds on the island for decades.
Landing on Torishima is not permitted (the volcano remains active and the colony is strictly protected), but the vessel circles close enough to observe birds in display and to photograph them at range. Black-footed Albatrosses, Bonin Petrels, and Streaked Shearwaters accompany the crossing over open Pacific. The Torishima cruise runs only a handful of times each year and sells out within days of announcement — add yourself to Saiyu Travel’s mailing list well in advance if this is your target.
May also marks the opening of the Teuri Island tours. Saiyu Travel’s Teuri Island Seabird Tour begins in late May, coinciding with the first return of Rhinoceros Auklets and Common Murres to the world’s largest Rhinoceros Auklet colony (over 800,000 breeding pairs). Spring arrivals at Teuri are slightly less dense than the June–July peak, but the island’s visual impact is already extraordinary.
The Izu ferry crossing remains excellent for albatrosses through May, making a combined spring itinerary — Torishima cruise in April or May, Teuri Island in May, Izu overnight crossing — feasible within a single trip.
Target species: Spring
- Short-tailed Albatross at breeding colony: April to May, Torishima cruise only
- Rhinoceros Auklet (returning breeders): May, Teuri Island
- Black-footed Albatross: April to May, Torishima cruise; October to May, Izu ferry
- Bonin Petrel: April to July, Izu and Ogasawara crossings
- Streaked Shearwater: August to November peak; spring birds appear May onwards
Summer (June to August): Auklets, Puffins, and Alcid Colonies
Summer is alcid season across Hokkaido. The Teuri Island Seabird Tour peaks from June through early July, when the evening spectacle of hundreds of thousands of Rhinoceros Auklets returning to their burrows after dark is at its most intense — a wave of birds arriving in the darkness that is unlike anything else in East Asian seabird birding.
The Ochiishi Nature Cruise summer programme runs June through August, targeting Tufted Puffins in the cliff-face colonies at Yururi and Moyururi islands, alongside Spectacled Guillemots, Ancient Murrelets, and Steller’s Sea Lions. This is the most comfortable season to visit northeastern Hokkaido, with reliable access and reasonable weather.
The Izu Islands ferry crossings shift character in summer. Albatross sightings drop off as breeding season constraints push birds from the route, but Streaked Shearwaters begin appearing in increasing numbers from late July. The Tokyo–Ogasawara Ferry continues year-round, and the 25-hour crossing in summer produces Brown Boobies, Wedge-tailed Shearwaters, Tristram’s Storm-Petrels, and the Bonin Islands’ endemic landbirds.
Svalbard and Alaskan equivalents draw attention in Northern Hemisphere summer, but Japan’s Hokkaido alcid colonies are genuinely among the largest in the western Pacific — and the Teuri Island twilight spectacle is in a category of its own.
Target species: Summer
- Rhinoceros Auklet (colony peak): June to early July, Teuri Island
- Tufted Puffin: June to August, Ochiishi (Yururi and Moyururi islands)
- Common Murre, Spectacled Guillemot: June to August, Ochiishi and Teuri
- Streaked Shearwater: July to November, all Izu routes (peak September to October)
- Brown Booby: June to October, Ogasawara ferry and island waters
Autumn (September to November): Shearwaters and the Return of Albatrosses
Autumn is the peak season for Streaked Shearwaters on the Izu ferry route. These large, distinctive shearwaters breed on islands throughout the western Pacific and gather in enormous numbers in Japanese waters from August through October, often forming massive feeding flocks visible from the ferry rail. Peak numbers occur in September and October.
Short-tailed Albatrosses return to the Izu Islands ferry route from October. The combination of massing shearwaters in early autumn and returning albatrosses from October makes the October overnight crossing from Tokyo particularly productive — potentially the best single crossing of the year for variety.
The Ogasawara ferry operates year-round and remains worthwhile in autumn for open Pacific species. Bonin Petrels, Matsudaira’s Storm-Petrels, and skuas are regular alongside shearwaters on longer passages. Autumn also brings vagrant potential, with strong westerly events occasionally producing unusual species on the outer Izu Islands.
Target species: Autumn
- Streaked Shearwater: September to October (peak), Izu and Ogasawara routes
- Short-tailed Albatross (return): October to May, Izu ferry
- Black-footed Albatross: October to May, Izu ferry
- Matsudaira’s Storm-Petrel: September to November, Ogasawara ferry
- Pomarine Jaeger, Long-tailed Jaeger: September to October, all offshore routes

Combining Trips: How to Plan a Japan Pelagic Itinerary
Japan’s pelagic destinations are spread across 1,500 km of latitude, from Hokkaido in the north to the Ogasawara Islands nearly 1,000 km south of Tokyo. Combining them in a single visit requires planning.
For Short-tailed Albatross: A May visit anchors itself around the Torishima cruise. Pair it with an Izu overnight ferry crossing (albatrosses are still common in May) and, if timing allows, the opening dates for Teuri Island. This single-country, multi-trip May itinerary is the closest Japan gets to a “greatest hits” pelagic visit.
For Hokkaido specialties: Late January through early March is the Rausu window. Add Ochiishi for winter Short-tailed Albatrosses and sea ducks, then consider a Tokyo Izu night crossing at the end of the trip — albatrosses are consistent through May.
For Auklets and Puffins: June to early July focuses on Teuri Island and Ochiishi summer tours. Add the Ogasawara ferry crossing for open Pacific species before or after.
Year-round option: The Tokyo–Ogasawara ferry runs three to four times monthly in every month of the year and is worth considering as a standalone trip whenever it fits your schedule.
Booking Lead Times
Torishima cruises and Teuri Island tours fill within days of announcement — these require joining Saiyu Travel’s mailing list and acting immediately. Rausu drift ice cruises book out well in advance for peak January dates; March departures are more available. The Izu and Ogasawara ferry tickets can typically be booked one to two months ahead. Ochiishi cruises require advance booking but are less time-critical than the specialist tours.
