Kanto · Guide de la Préfecture
Le plus grand complexe thermal du Japon, un moulin à soie UNESCO, des zones humides alpines sauvages et le berceau de la poupée daruma
Gunma est la capitale des onsen du Japon dans l'esprit de nombreux voyageurs japonais — Kusatsu Onsen attire à elle seule quatre millions de visiteurs par an grâce à ses eaux fameusement acides et au théâtral champ d'eau chaude Yubatake en son centre. Mais la préfecture offre bien plus : un moulin à soie inscrit au Patrimoine Mondial UNESCO qui raconte l'histoire de la révolution industrielle japonaise, les zones humides alpines sauvages du Parc National d'Oze, la photogénique ville thermale à marches de pierre d'Ikaho, et les lacs de caldera des hautes terres du Mont Akagi. Pour ceux qui veulent un Japon au-delà des sentiers touristiques — mais toujours à moins de 2 heures de Tokyo — Gunma répond à l'appel.
Gunma est accessible par Shinkansen jusqu'à Takasaki (50 min depuis Tokyo), qui sert de principale porte d'entrée pour toute la préfecture. Kusatsu Onsen est à encore 90 min de bus depuis Takasaki. La plupart des attractions rurales nécessitent soit une correspondance en train local, soit une voiture de location — Gunma est l'une des préfectures les plus adaptées aux voyageurs indépendants motorisés du Japon.
Des guides complets pour planifier chaque aspect de votre séjour — des incontournables aux meilleurs restaurants et événements saisonniers.
Japan's most celebrated hot spring resort — the iconic Yubatake (hot water field) at the town centre pumps 32,300 litres of acidic water per minute, surrounded by Edo-period bathhouses and lodgings.
Japan's first modern silk mill (1872), now a UNESCO World Heritage Site — an extraordinary French-Japanese industrial complex with original brick filatures and a fascinating history of Japan's modernisation.
A charming Meiji-era hot spring resort built on a steep hillside, with a famous 365-step stone stairway lined with ryokan, souvenir shops, and temples — one of Japan's most photogenic onsen towns.
Takasaki produces 80% of Japan's daruma good-luck dolls. The Daruma Market in January is legendary, but year-round the town's shops and Shorinzan Darumaji temple celebrate this iconic red figure.
Gunma's prefectural capital, known for its grand Akagi Shrine on the shore of Lake Akagi, the largest rose garden in eastern Japan, and lively local shotengai shopping streets.
Steam-cooked buns (manju) made using the natural hot spring steam of Kusatsu — a beloved resort souvenir sold fresh from street stalls around the Yubatake, eaten while still warm.
Gunma is a major cattle-raising prefecture producing premium Jomo Beef (上州牛). Yakiniku restaurants across Maebashi and Takasaki serve this highly marbled local wagyu at prices well below Tokyo.
One of Japan's three great udon varieties — silky smooth flat noodles made with the pure water of Ikaho's mountains, served chilled on a lacquer tray with dipping sauce and sesame.
The Agatsuma and Tone river valleys are lined with apple, pear, and plum orchards offering pick-your-own experiences from August through November — a popular autumn countryside outing.
Gunma produces 90% of Japan's konnyaku (konjac jelly). Try it in traditional oden stew, grilled on a stick with miso, or as sashimi konnyaku — a surprisingly versatile local staple.
Japan's largest high-altitude wetland spanning Gunma, Fukushima, and Niigata — golden skunk cabbage in June, wildflowers in summer, and crimson foliage in autumn make it one of Japan's top nature destinations.
An ancient caldera volcano rising to 1,828 m with three crater lakes, ancient beech forests, and sweeping Kanto Plain views — superb hiking in summer and striking rime ice in winter.
A remote hot-spring hamlet in a deep mountain gorge said to be the model for the setting of Studio Ghibli's Spirited Away — its old wooden bathhouses and bridge are hauntingly atmospheric.
A serene caldera lake on Mt. Haruna's rim, famous for brilliant autumn foliage, winter ice fishing, and panoramic views of the surrounding peaks from the lakeside promenade.
Known as the 'Niagara of the East' — a wide curtain of water tumbling over basalt columns on the Tone River, framed by cedar forest and vivid autumn maples.
Kusatsu's waters are so hot (92°C at source) they must be cooled by the traditional yumomi method — large wooden paddles rhythmically churned through the bath to cool without diluting the minerals. Twice-daily performances at the Netsunoyu bathhouse, accompanied by folk songs, demonstrate this 400-year practice as theatrical art before visitors enter the actual bath.
The Tone River gorge above Minakami offers some of Kanto's most accessible white-water rafting, with guided Class III runs through dramatic granite canyon walls just 2 hours from Tokyo. Spring snowmelt creates the most powerful flows (May–June), while summer offers warmer water for families. Bungee jumping and canyoning can be combined in the same trip.
Japan's most celebrated hot spring resort — the iconic Yubatake (hot water field) at the town centre pumps 32,300 litres of acidic water per minute, surrounded by Edo-period bathhouses and lodgings.
One of Japan's top ski resorts with reliable powder snow, 21 courses, and night skiing — and uniquely, ski-lift access from the hot spring town itself for a ski-and-onsen combination day.
A free daily performance at the Yubatake-side bathhouse — local attendants perform the traditional 'jikan-yu' hot water stirring ceremony to cool the scalding 95°C spring water, set to folk song.
A remote hot-spring hamlet in a deep mountain gorge said to be the model for the setting of Studio Ghibli's Spirited Away — its old wooden bathhouses and bridge are hauntingly atmospheric.
Takasaki produces 80% of Japan's daruma dolls — the round, eyeless papier-mâché good-luck figures purchased at New Year. The Shorinzan Daruma Temple fair (January 6–7) draws 400,000 visitors to browse thousands of daruma in every size, from ¥500 palm-sized to ¥30,000 giant versions, amid the largest concentration of daruma artisans in Japan.
Kusatsu Onsen's winter festival combines dazzling snow illuminations around the Yubatake with fireworks bursting over the steaming hot spring field — one of Japan's most atmospheric winter events.
Every June, Oze National Park's marshlands erupt in golden-white skunk cabbage (mizubasho) blooms across the highland plateau — a uniquely Japanese spring nature spectacle.
One of Japan's largest traditional markets, held January 6–7 at Shorinzan Darumaji Temple — over 100 stalls selling daruma dolls of every size, drawing 200,000 visitors to greet the new year.
Mt. Akagi's crater lakes and beech forests turn gold and crimson from mid-October, with viewing events, food stalls, and photography contests around Lake Onuma.
An autumn celebration of Tomioka's silk-weaving heritage with traditional loom demonstrations, silk product markets, and guided tours of the UNESCO World Heritage mill complex.
A one-night stay at a traditional ryokan in Kusatsu or Ikaho hot spring resorts is the quintessential Japanese travel experience: arriving to be met in yukata, served elaborate kaiseki multi-course dinner in your room, soaking in rotemburo (outdoor stone bath) under stars, sleeping on futon on tatami, and waking to a Japanese breakfast of grilled fish, tofu, and pickles.
