NORTHERN LAND HOKKAIDO

One of Hokkaido's 14 regions

Oshima渡島

Hakodate's night view, castle towns and the shinkansen gateway.

11 municipalities🗓️ Late April–early May for Matsumae and Goryokaku cherry blossoms; the night view and markets shine year-round.

Oshima is Hokkaido's historic south — the first part of the island to open to the outside world. Hakodate wears that history beautifully: Motomachi's churches and slopes, red-brick warehouses on the bay, a morning market that justifies the trip alone, and the celebrated night view from Mt. Hakodate.

Beyond the city, Edo-era Japan lingers at Matsumae, the island's only castle town, and Onuma's island-dotted lakes sit beneath the elegant cone of Mt. Komagatake. Since the shinkansen reached Shin-Hakodate-Hokuto, this is where many Hokkaido journeys now begin.

🧭 The Hokkaido Shinkansen arrives at Shin-Hakodate-Hokuto; Hakodate also has its own airport with Tokyo flights.
