Insider tip — Kamiyu Onsen Club, the upper hot spring, serves the Echigo Mountains heartland of Uonuma where the legendary yukiguni snow country receives the heaviest snowfall in populated Japan — up to three metres or more. Novelist Kawabata Yasunari opened his Nobel Prize-winning Snow Country with the words the train emerged from the long tunnel at the border into the snow country, capturing the transformation that still greets visitors entering Uonuma from the Kan-etsu Tunnel.
