Dense, salty water — you float without effort.
Taiki Onsen is located in Taiki, a coastal town in the Tokachi Subprefecture of southeastern Hokkaido facing the Pacific Ocean, and home to the JAXA Taiki Aerospace Research Field — one of Japan's primary testing grounds for high-altitude balloons and experimental aircraft, a facility that has launched dozens of scientific research flights into the stratosphere from this remote Pacific coastal location whose sparse air traffic and stable atmospheric conditions make it ideal for aerospace experimentation. The town's Pacific coast setting, with views of the open ocean and the distant Kuril Islands on clear days, creates a sense of standing at the edge of Japan's eastern frontier, where the continental shelf drops away into the deep Pacific and the cold Oyashio Current delivers rich nutrients to productive fishing grounds. The onsen here provide silica-rich thermal bathing in a community where the frontier spirit of aerospace research and traditional Pacific coastal fishing coexist in a landscape of distinctive eastern Hokkaido character.
