This does still leave Shikoku shinkansen-free, though, and the vast majority of Hokkaidō.
Japanese cuisine is famously light on dairy, but Hokkaidō is definitely the exception.
The big gaps at the moment are in Shikoku(the
fourth-largest island, just by Kyūshū) and almost all of Hokkaidō;
The pilot shaft of the Seikan Tunnel,
the world's longest sub-aqueous tunnel(53.85 km) between the Japanese islands of Honshū and Hokkaidō,
Hokkaidō's climate also makes it ideal for viticulture,
unlike much of the rest of Japan, and there are several wineries in Sapporo.
At 425 metres(1,394 ft),
it is slightly deeper than Lake Shikotsu in Hokkaidō(423.4 meters),
and is the 17th deepest lake in the world.
Sapporo, unsurprisingly, is the culinary capital of Hokkaidō, and the perfect place to sample some surprisingly un-Japanese Japanese dishes-
and not only dairy.
This chilled-out city is the capital of Hokkaidō, Japan's northern island which has 22
percent of the country's landmass but only five percent of its population.
Unlike the rest of Japan, Hokkaidō doesn't have a rainy season-
so there's no need to endure those days of sticky heat, humidity and sudden downpours.
A number of the world's best examples of somma volcanoes are found on Russia's Kamchatka Peninsula and
the Kuril Islands that stretch south from Kamchatka to Hokkaidō Japan.
