Shima Onsen Grand occupies a mountain gorge spa town in Nakanojo famous throughout Japan as one of the inspirations — alongside Dogo Onsen and the Sekizen-kan ryokan — for the magical bathhouse in Studio Ghibli's beloved animated film Spirited Away, whose director Hayao Miyazaki reportedly drew on the architecture and atmosphere of traditional Japanese onsen towns while creating his vision of the spirit world. The Sekizen-kan, one of Japan's oldest surviving wooden ryokan, stands at the heart of the town with its vermilion bridge and tiered bathhouse reflected in the Shima River, creating a scene of timeless atmospheric beauty. Soaking in Shima's geothermal mineral waters amid this forested gorge setting offers one of Japan's most evocative onsen experiences, infused with both the aesthetics of traditional inn culture and the enchanted atmosphere of a story that captivated audiences worldwide.

Insider tip — Shima Onsen occupies a deep forested gorge along the Nakatsu River in Gunma Prefecture, a region historically celebrated for its hot springs that inspired the folktale basis of Studio Ghibli's Spirited Away. Silica-rich spring water at 42°C flows through traditional wooden ryokan bath halls perched above the rushing river. The gorge is accessible only by a narrow mountain road, keeping the atmosphere intimate and unhurried. Winter visits are especially atmospheric, with snow blanketing the cedar canopy above the steaming outdoor pools.
