Sobetsu壮瞥町
A volcano born in a wheat field, and orchards below it
Iburi region · Noboribetsu, Lake Toya and Upopoy: plan a trip through Iburi.
Sobetsu watches over Showa-Shinzan — the volcano that grew out of a wheat field in the 1940s — and throws an international snowball-fight championship.
Sobetsu wraps around the eastern shore of Lake Toya and holds the region's strangest landmark: Showa-Shinzan, a red lava dome that pushed up out of a farmer's wheat field between 1943 and 1945 and still steams. Mt. Usu rises beside it, and the lake's east shore has its own hot springs and viewpoints. Down in the valleys the town is orchard country, with apples, cherries and grapes in pick-your-own farms. It suits families and anyone who wants to stand next to a volcano without a long hike.

What to see in Sobetsu
Showa-Shinzan
昭和新山
The lava dome that grew out of farmland during the war years, recorded day by day by the local postmaster who later bought the mountain to protect it. It is a national natural monument and still vents steam from its rust-red flanks.
Mt. Usu viewpoints
有珠山の展望
From the base of Showa-Shinzan a ropeway climbs to the shoulder of Mt. Usu, with a platform overlooking the dome, Lake Toya and Volcano Bay, and a trail on to the rim of the 1977 crater.
Sobetsu Park plum grove
壮瞥公園の梅林
A hilltop park above the lake planted with hundreds of plum trees that bloom in May, far later than the rest of Japan, with Lake Toya, Nakajima and Mt. Yotei laid out below. One of the best views in the area.
Michi-no-Eki Sobetsu
道の駅そうべつ情報館i
The roadside station on Route 453 doubles as the town's volcano information centre, with exhibits on the 2000 Usu eruption and the geopark, and a produce corner heavy with the town's fruit in season.
Getting to Sobetsu
There is no railway in Sobetsu; the nearest stations are Toya and Date-Mombetsu on the JR Muroran Main Line, both limited-express stops with bus connections. Route 453 links the town directly to Sapporo in about two hours via Otaki, and New Chitose Airport is roughly 1.5 to two hours by car. Route 37 and the Do-o Expressway pass just south.
Iburi region: Plan rail journeys to Shiraoi, Noboribetsu or Toya, then check the final local connection. Noboribetsu Station is not in the hot-spring town, and Toya Station is not on the Toyako Onsen lakefront. Check bus or hotel pickup times before booking accommodation; a rail journey alone does not get you to the ryokan door.
When to visit Sobetsu
May for plum blossom on the hill, July for cherries and August to October for apples and grapes at the orchards. February brings the international snowball-fight championship at the foot of Showa-Shinzan, the town's odd and cheerful winter signature.
What to eat in Sobetsu
Sobetsu is Iburi's fruit basket: apples, cherries, grapes, plums and pears grown in the sheltered valleys, sold at orchard stands and turned into juice and cider. Lake Toya adds kokanee salmon, and the volcanic soil grows good potatoes and beans.
