Ginzan Onsen โ Taisho-Era Lantern Town
Ginzan Onsen is widely regarded as Japan's most photogenic hot spring town โ a handful of multi-storey Taisho-era timber ryokan line both banks of a narrow mountain stream in a tight valley, all preserved in immaculate 1920s style. After dark, the buildings are illuminated by traditional gas lanterns reflected in the flowing water below, creating a scene so cinematic that it reportedly inspired the bathhouse in Miyazaki's 'Spirited Away'. Daytrippers are allowed but an overnight stay is transformative.
