Insider tip — Genki Land at Kasukawa Onsen serves Maebashi City, the capital of Gunma Prefecture whose northern skyline is dominated by the triple volcanic peaks of Akagi, Haruna, and Myogi — the Three Gunma Mountains celebrated in national waka poetry since the Man-yoshu anthology. Maebashi was historically one of Japan most important silk-reeling centers where Meiji-era spinning mills powered by the Tone River tributaries produced the raw silk that earned Japan its first substantial export revenues — a heritage commemorated in the Tomioka Silk Mill now a UNESCO World Heritage site.
