Insider tip — In Shibukawa, the gateway city to Gunma's celebrated hot spring triangle — Ikaho, Kusatsu, and Shima — Komochi no Yu (spring of the child-bearing mountain) draws its name from Mount Komochi, the local landmark overlooking the Agatsuma River basin; the sulfurous volcanic waters here tap the same geothermal system that makes Gunma Japan's most thermally active prefecture.
