Tokorozawa Onsen Saitama is a hot spring in Tokorozawa, a large city in western Saitama Prefecture, Japan, celebrated as the site of Japan's first airfield — opened in 1911, making it Japan's birthplace of aviation history — and internationally recognized as the city from which Studio Ghibli's 'My Neighbor Totoro' drew its inspiration, with the Sayama Hills forests around Tokorozawa serving as the fictional setting for the beloved animated film's landscape. The naturally bicarbonate-rich spring waters here, within a long thermal tradition, are associated with well-being and relaxation thanks to their gentle alkaline character, offering an accessible soak in a city that combines Japan's aviation heritage with one of its most cherished animated film legacies. Soaking in Tokorozawa's bicarbonate mineral waters amid the Totoro-inspiring Sayama Hills landscape and Japan's aviation birthplace heritage provides a uniquely nostalgic and culturally resonant Saitama wellness experience.
