Gunma Hidden Gems

Gunma is landlocked, mountainous on three sides, and sits on so much geothermal water that hot springs are less an attraction than an industry. Kusatsu alone discharges more litres per minute than any other resort in Japan, at temperatures too hot to enter directly — which is why the yubatake in the town centre exists, a wooden cooling apparatus that doubles as the main square, and why the yumomi paddle-stirring performance survives. The plain around Maebashi and Takasaki was silk country: Tomioka's mill, built in 1872 with French engineers and machinery, industrialised the trade that paid for Japan's early modernisation, and the buildings are still standing in full. Above the plain the land rises to Mt. Haruna and Mt. Akagi, both collapsed volcanoes with lakes in their craters, and to the Oze marshes on the northern border. The winds off those mountains in winter are dry and hard enough to have their own name locally.

When to Go

The onsen towns are winter destinations and Kusatsu at 1,200 metres gets real snow from December to March, with ski runs above the town. The plain below is the opposite: Maebashi and Tatebayashi are among the hottest places in Japan in August, regularly above 35°C, and the dry winter wind keeps the lowlands clear and snow-free. Oze's marshland boardwalks open from late May, with cotton grass in June and alpine colour in early October. Mt. Haruna and Mt. Akagi are best from May to November. Late October is when the mountain foliage and the still-warm baths overlap.

Getting Around

The Joetsu and Hokuriku Shinkansen both cross the prefecture, putting Takasaki about 50 minutes from Tokyo — one of the shortest shinkansen hops in the country. From there the JR Agatsuma line runs to Naganohara-Kusatsuguchi, where a 25-minute bus finishes the trip to Kusatsu; direct limited express services also run from Ueno. Ikaho and the Tomioka mill are reachable by bus and local train from Takasaki. Beyond that, the mountain roads matter more than the rails: Oze, Akagi and the Nikko-Gunma border need a car or a seasonal bus, and several passes close under snow from November into spring.

Local Food

Gunma grows a great deal of wheat, which is why the local staples are flour rather than rice. Mizusawa udon, made along the approach to Mizusawa temple in Ikaho, is one of the three named udon of Japan and is served cold with dipping sauce. Yakimanju are fist-sized steamed buns skewered and painted with sweet miso, sold at festivals and roadside stands across the plain. Shimonita in the southwest grows a thick, short negi eaten cooked rather than raw. Konnyaku, made from local devil's tongue root, appears in almost everything.
