The snow has been falling since we arrived in Nozawa Onsen, a traditional Japanese town that sits at the center of a skiing area in mountainous Nagano province. It’s a chilly late afternoon in February. With the ski lifts already closed, I stroll across charming, wood-paneled streets lined with buildings that have stood since the Edo period (1603-1868). Each of the narrow streets is fringed with steaming water as if the entire town was built around a network of mountain streams. The water running from the volcanic springs is channeled away to heat private houses and the almost 30 public Onsens, from which the town gets its name. Nosawa gained a good deal of popularity thanks to these hot spring baths many years before snowsports became a thing in the country.
