Insider tip — Onaga Tani Onsen at the Shirokimine foothill community center serves the upper Shogawa River valley of Toyama Prefecture where the Gokayama district of Nanto City preserves a cluster of UNESCO World Heritage gassho-zukuri farmhouses. The Ainokura and Suganuma historic villages in Gokayama survived centuries of isolation in one of Japan snowiest landscapes — receiving up to three metres of snow annually — their deep-pitched thatched roofs engineered to shed the extraordinary weight of Hida mountain winters that tested every generation of their inhabitants.
