Why visit Gunma
Gunma is Tokyo’s hot spring back garden, and its resorts are the working kind rather than the polished kind. Kusatsu Onsen is built around the Yubatake, an open wooden channel in the middle of town where the water is cooled in the air before it reaches the baths — you smell the sulphur before you see it. Ikaho Onsen climbs a long stone stairway lined with inns and shops. For something other than bathing, Mount Tanigawa offers a ropeway into serious mountain scenery, and the Tomioka Silk Mill, a UNESCO World Heritage site, preserves the brick factory where Japan’s modern silk industry began.
Getting to Gunma
Gunma is close to Tokyo on the Joetsu and Hokuriku Shinkansen lines, and Kusatsu is reached by limited express and bus in a few hours — close enough that many people come for one night. The prefecture is mountainous, so the resorts sit apart from each other and combining two in a trip means either a car or a long bus day. Winter brings snow and skiing to the north, and the hot springs are at their best in exactly that weather.
