Insider tip — 'Kita no Yu' (北の湯 — northern spring) at Shin Naie Onsen Hotel in Naie-cho, Sorachi district, Hokkaido — the former coalfield heartland of central Hokkaido. Naie was part of the Sorachi coalfield that powered Hokkaido's industrial development from the Meiji era. The post-coal era has left a quieter Naie of rice paddies, dairy farms, and thermal springs. 'Kita no Yu' — the northern spring — is perfectly named for a hot spring hotel at the northern edge of Japan's agricultural heartland, where winters are long and thermal warmth essential.
