Gunma Prefecture, located in the heart of Japan’s Kanto region, is a hidden gem for travelers seeking an authentic cultural experience beyond the well-trodden paths of Tokyo and Kyoto. Known for its rich history, stunning natural landscapes, and deep-rooted traditions, Gunma offers a rare glimpse into Japan’s true essence. Whether you are interested in traditional hot springs, historical sites, or rural adventures, Gunma has something for everyone.
Let’s embark on a journey to explore the cultural wonders of this remarkable prefecture.
1. The Onsen Culture: Gunma’s Hot Spring Retreats
Kusatsu Onsen: Japan’s Premier Hot Spring Destination

Kusatsu Onsen is one of Japan’s most famous and highly regarded hot spring towns. The centerpiece of Kusatsu is the Yubatake, a large hot water field where steaming mineral-rich waters flow continuously.
Visitors can witness the traditional yumomi performance, where local women stir the hot spring water with wooden paddles to cool it down naturally.

Strolling through the town’s charming streets, soaking in an open-air bath, and enjoying local delicacies like onsen manju (sweet steamed buns) make for an unforgettable experience.
Ikaho Onsen: A Historic Spa Town with Stone Steps

Another must-visit onsen town in Gunma is Ikaho Onsen. Unlike Kusatsu, which is known for its acidic waters, Ikaho’s iron-rich springs give the baths a distinctive golden hue. The town is characterized by its iconic 365 stone steps, lined with traditional inns, souvenir shops, and nostalgic arcades.
Exploring Gunma’s Rich History and Heritage
Tomioka Silk Mill: A UNESCO World Heritage Site

Gunma played a pivotal role in Japan’s modernization, particularly in the silk industry. The Tomioka Silk Mill, a UNESCO World Heritage Site, stands as a testament to Japan’s industrialization in the late 19th century.
Today, visitors can tour the well-preserved buildings, learn about the silk-making process, and understand the historical significance of this site in Japan’s development.
Lockheart Castle: A European Touch in Rural Japan

Nestled in the hills of Gunma, Lockheart Castle is a surprising yet enchanting attraction. Originally built in Scotland in 1829, the castle was transported to Japan and reconstructed stone by stone. Today, it serves as a romantic getaway, often used as a venue for weddings and film shoots.
Visitors can dress up in period costumes, explore the castle’s museum, and enjoy the picturesque surroundings.
Outdoor Adventures in Gunma’s Natural Wonderland
Mount Tanigawa: A Paradise for Hikers and Climbers

Mount Tanigawa, a popular peak for both seasoned climbers and casual hikers, offers breathtaking views and challenging trails. The ropeway ride to the Tenjindaira Plateau provides an easier way to enjoy the spectacular scenery, especially during autumn when the foliage turns vibrant shades of red and orange.
Oze National Park: A Tranquil Escape into Nature

For those seeking a peaceful retreat, Oze National Park is a must-visit. The park is particularly stunning in early summer, when the white mizubasho (skunk cabbage) flowers bloom, and in autumn, when the golden grasses create a mesmerizing landscape.
Oze’s well-maintained hiking trails make it accessible for visitors of all levels, offering a perfect balance of adventure and relaxation.
Gunma’s Unique Culinary Delights
Mizusawa Udon: A Taste of Traditional Handcrafted Noodles

Gunma is famous for its noodles, and Mizusawa Udon is one of its most cherished specialties. Made using pure local water and high-quality wheat, Mizusawa Udon is characterized by its smooth, chewy texture.
Many udon restaurants near Ikaho Onsen serve this local dish, providing an excellent culinary stop during a cultural exploration of Gunma.
Yakimanju: A Sweet and Savory Local Favorite

Yakimanju is another Gunma specialty that visitors should not miss. This grilled bun, coated in a sweet and salty miso sauce, is a popular street food enjoyed by locals. The slightly charred exterior and soft, fluffy interior make for a delightful contrast in texture and taste.
Traditional Festivals and Cultural Experiences
Takasaki Daruma Market: A Celebration of Good Fortune

Takasaki City, known as the birthplace of the Daruma doll, hosts the annual Takasaki Daruma Market in early January.
This festival attracts thousands of visitors who come to purchase Daruma dolls, which are symbols of perseverance and good luck. Traditionally, one eye of the Daruma is painted when setting a goal, and the other eye is filled in once the goal is achieved.
Numata Matsuri: A Dynamic Summer Festival

Held in August, Numata Matsuri is one of Gunma’s most exciting festivals. The highlight of the festival is the dashi (elaborate festival floats) parade, where locals dressed in traditional attire pull beautifully decorated floats through the streets.
