Insider tip — Mochizuki Onsen Midori no Mura sits on the Tateshina plateau near Sakuho in Nagano at around 900 metres elevation, tapping the bicarbonate-rich thermal springs typical of the Yatsugatake volcanic range. The silky, slightly alkaline water is celebrated locally for its skin-smoothing properties, earning the Japanese nickname bijin-no-yu or beauty water. The facility is set in a green resort complex offering lodging and dining, surrounded by larch forests brilliant with autumn colour in October. Nagano's crisp mountain air and the warm bicarbonate baths make a restorative combination after hiking the Yatsugatake trails.
