Tobishima, a tiny island 39km off the coast of Akita Prefecture in the Sea of Japan, is Japan’s most celebrated migration hotspot — a geographical funnel for East Asian migratory birds crossing the sea. In spring and autumn, extraordinary concentrations of rare flycatchers, warblers, thrushes, and raptors accumulate on this small island, attracting dedicated birders from across Japan.
What to See
Rare Migrants
The spring migration (late April to June) brings extraordinary concentrations of Yellow-rumped Flycatcher, Blue-and-white Flycatcher, Narcissus Flycatcher, Eyebrowed Thrush, and various Phylloscopus warblers. The island regularly produces vagrant species from Central Asia and Siberia — Brown-chested Jungle Flycatcher, Asian Brown Flycatcher, Tiger Shrike, and Red-flanked Bluetail are consistent specialties.
Raptors
Grey-faced Buzzard, Japanese Sparrowhawk, and Eurasian Hobby pass in numbers during migration. Osprey is regular in both seasons. Breeding seabirds include Black-tailed Gull, Pelagic Cormorant, and Temminck’s Cormorant on the rocky cliffs.
Best Time to Visit
- Late April – early June: Peak spring migration; the classic Tobishima experience
- September – October: Autumn migration; returning raptors and thrushes
Travel Tips
A daily ferry runs from Sakata Port (Yamagata Prefecture) to Tobishima — the crossing takes about 2.5 hours. Accommodation on the island is extremely limited (just one small guesthouse) and must be booked months in advance for peak migration dates. Most visitors do a day trip, leaving Sakata at 8am and returning by evening. The entire island can be walked in a few hours, making it perfect for thorough coverage.
