Here’s a detailed guide to the Top 10 Places of Gunma that will make your trip a truly magical experience.
1. Kusatsu Onsen
When it comes to iconic hot spring towns in Japan, Kusatsu Onsen reigns supreme. Renowned for having some of the most sulfur-rich waters in the country, this destination offers both healing and relaxation in equal measure. The centerpiece of the town, Yubatake (Hot Water Field), is a mesmerizing sight where steaming waters gush out and flow through wooden channels.
Visitors can enjoy public foot baths, traditional ryokan stays, and open-air baths surrounded by snow in winter. Kusatsu’s onsen experience is complemented by local performances, like the yumomi water-stirring show, which adds a traditional touch to this rejuvenating escape.
2. Mount Tanigawa (Tanigawadake)
For adventure seekers and nature lovers, Mount Tanigawa is a must-visit. Rising along the border of Gunma and Niigata Prefectures, it offers some of Japan’s most breathtaking alpine views. You can take the Tanigawadake Ropeway to witness panoramic vistas or hike one of the scenic trails during summer and autumn. In winter, the area transforms into a paradise for skiers and snowboarders.
Despite its reputation as a challenging mountain, accessible hiking routes and stunning landscapes make Mount Tanigawa a year-round favorite for outdoor enthusiasts.
3. Ikaho Onsen
Another famous hot spring town in Gunma is Ikaho Onsen, known for its unique reddish-brown iron-rich waters. The charm of Ikaho lies in its nostalgic ambiance—stone stairways lined with inns, cafes, and shops selling local specialties. The 365 Stone Steps Street is the heart of the town, leading visitors up to Ikaho Shrine at the top.
Along the way, you can soak in traditional baths, taste sweet onsen manju (steamed buns), and enjoy the gentle mountain air. Ikaho perfectly blends old-world romance with modern comfort.
4. Tomioka Silk Mill
A UNESCO World Heritage Site, Tomioka Silk Mill stands as a proud reminder of Japan’s industrial revolution. Established in 1872, it was Japan’s first modern silk reeling factory, symbolizing the country’s leap into modernity.
Visitors can explore the well-preserved red-brick buildings, learn about the silk production process, and understand how this mill influenced Japan’s economic growth. The guided tours and exhibitions here make it a fascinating destination for history and culture lovers.
5. Oze National Park
Nature at its purest awaits you at Oze National Park, one of Japan’s most beautiful and untouched wilderness areas. Spanning multiple prefectures, including Gunma, Oze is famed for its expansive marshlands, wooden boardwalks, and mountain backdrops.
The Ozegahara Marshland is especially captivating in spring with blooming skunk cabbage and in autumn when the marsh turns golden. Hiking through this park offers a serene connection with nature, clean air, and stunning seasonal changes. It’s a dream destination for hikers, photographers, and anyone seeking tranquility.
6. Lockheart Castle
Yes, you read that right—there’s a European-style castle in the middle of Gunma! Lockheart Castle was originally built in Scotland in 1829 and later transported stone by stone to Japan. Today, it stands as a romantic landmark and theme park in Takayama Village. The castle exudes a fairy-tale charm and is a popular spot for weddings, photo shoots, and film locations.
Visitors can try on royal costumes, explore the doll museum, and enjoy panoramic countryside views. It’s an unexpected but delightful mix of European elegance and Japanese hospitality.
7. Mizusawa Temple (Mizusawa Kannon)
Rich in history and spiritual energy, Mizusawa Temple is one of Gunma’s most revered Buddhist temples. Dating back over 1,300 years, the temple complex is surrounded by lush cedar forests and peaceful walking paths. The six-faced Kannon statue is the main deity, symbolizing compassion and wisdom.
The temple grounds also host a charming street of udon shops, as Mizusawa is famous for its hand-pulled udon noodles. Visitors often combine temple visits with enjoying a hearty bowl of this regional specialty.
8. Haruna Lake and Mount Haruna
A scenic gem that perfectly combines natural beauty and cultural significance, Lake Haruna sits at the base of the majestic Mount Haruna, a dormant volcano. The area offers boating, fishing, and hiking opportunities, with stunning reflections of the surrounding mountains on the lake’s surface.
During winter, the lake freezes over, creating a magical landscape. Near the lake stands Haruna Shrine, one of Gunma’s most picturesque shrines, nestled deep within a mossy forest. The serenity of this spot makes it ideal for those seeking peace and scenic charm.
9. Minakami Onsen and Adventure Area
For those craving a mix of relaxation and adrenaline, Minakami Onsen is the ultimate destination. Located along the Tone River, this region combines soothing hot springs with outdoor adventures. You can go whitewater rafting, canyoning, and bungee jumping during warmer months, or enjoy skiing and snowboarding in winter.
The Takaragawa Onsen, one of the largest outdoor baths in Japan, is a must-visit—imagine soaking in a riverside bath surrounded by forests and snow. Minakami perfectly captures Gunma’s dual nature: thrilling adventure and peaceful rejuvenation.
10. Shima Onsen
Hidden deep in the mountains, Shima Onsen is one of Japan’s oldest and most tranquil hot spring resorts. Its name means “forty thousand,” symbolizing the 40,000 ailments the waters are said to cure. The town is filled with retro ryokans, wooden bridges, and quiet riversides, giving it a nostalgic charm straight out of an anime scene.
The Sekizenkan Ryokan, one of Japan’s oldest inns, is rumored to have inspired the bathhouse in the famous Studio Ghibli film Spirited Away. Visitors come here to unwind, reflect, and immerse themselves in the timeless rhythm of rural Japan.
