Sennokaze Biei Onsen in Biei, Hokkaido, draws sulfate-rich thermal waters in the Tokachi highland north of Furano — a rolling farmland plateau of patchwork lavender fields, wheat, and potato cultivation made globally famous by photographer Shinzo Maeda's images that single-handedly created Hokkaido's image as Japan's pastoral paradise. The thermal pools provide an authentic Hokkaido agricultural-community bathing experience — miners, farmers, and ski-resort workers soaking in the same waters — at the foot of the Daisetsuzan National Park's volcanic highland where the Tokachi River originates and Hokkaido's most remote wilderness begins. The Blue Pond of Biei — an artificially formed aluminum-stained lake of ethereal cerulean color that became one of Apple's most downloaded desktop backgrounds globally — is accessible from the onsen area, combining viral natural beauty with the restorative thermal waters of Hokkaido's most photogenic agricultural highland.
