Japan, the undisputed king of hot springs, offers an incredible variety of thermal experiences, especially during the chilly winter months. While many onsen resorts are booked solid during this time, I've made it my mission to discover some hidden gems, particularly those famed for their beautifying properties. Join me, Mark, a seasoned backpacker with a passion for exploring Asia, as I unveil two incredible onsen experiences and a delightful culinary adventure in Japan.
Kawachu Onsen: A Secret Oasis of Rejuvenation
My top recommendation is Kawachu Onsen, one of Japan's top three "bijin-no-yu" (beauty springs) located in Gunma, a region often called the "Onsen Kingdom." This hidden gem, a member of the Secret Hot Spring Preservation Society, offers a traditional ryokan experience that’s hard to find advertised online. Imagine sliding open the shoji screens to the aroma of tatami mats, a quintessential Japanese experience. The ryokan provides all the necessary amenities and boasts an incredible rotenburo (open-air bath) filled with the natural, 35°C waters of Kawachu Onsen. This moderate temperature allows for long, luxurious soaks.
I highly recommend staying overnight (I stayed for one night) to fully immerse yourself in the experience. The ryokan offers "ichiboku-nishoku," which means one night's stay with two meals. The dinner was a simple yet satisfying traditional Japanese set meal, complete with grilled fish, miso soup, homemade pickles, and even sashimi. The best part? The price is incredibly affordable.
| Feature | Description |
|---|---|
| Location | Gunma Prefecture, Japan |
| Spring Type | Bijin-no-yu (Beauty Spring) |
| Temperature | 35°C |
| Accommodation | Traditional Ryokan (Japanese Inn) |
| Meals | Ichiboku-nishoku (One night with two meals) |
| Approximate Price | ¥10,000 (approximately $70 USD) |
Kusatsu Onsen: A Spectacle of Nature and Tradition
After a rejuvenating night at Kawachu Onsen, I suggest a day trip to nearby Kusatsu, another renowned onsen town just 30 minutes away. Kusatsu boasts the highest natural hot spring output in Japan, ensuring a fresh and invigorating soak.
The heart of Kusatsu is the "Yubatake," a central hot spring field where you can witness the steaming, slightly green-tinted waters flowing into the river. Two unique experiences await you here: observing the "yu-no-hana" (hot spring flowers), delicate yellow mineral deposits left behind as the water evaporates, and witnessing "yu-momi," a traditional practice where women rhythmically stir the hot spring water with long wooden paddles, accompanied by local folk songs and dances.
Beyond the Yubatake, explore the serene beauty of Kosenji Temple, with its vibrant red five-storied pagoda set against a backdrop of snow-covered landscape. In the late afternoon, head to the picturesque Nishi-no-Kawahara Park, where the illuminated scenery and free footbaths offer a truly magical experience (remember to bring your own towel!).
Heiwa Soba: A Taste of Japanese Culture and Culinary Comfort
No trip to Kusatsu is complete without a visit to Heiwa Soba. This restaurant offers delicious and affordable soba noodles with a deep connection to Japanese culture. Their specialty is "kyu-wari" soba, made with 90% buckwheat and 10% wheat flour, resulting in a slightly chewier texture. Whether you prefer hot or cold soba (I opted for a warming bowl on a cold winter's day), be sure to add tempura flakes for an extra layer of flavor. The reasonable price (around ¥1000 per bowl) makes this culinary experience even more enjoyable.
Soba noodles hold a special significance in Japanese culture, often served during celebrations like moving into a new home or on New Year's Eve. They are considered a symbol of longevity, and tradition dictates slurping them loudly, a sign of appreciation and good manners.
Ryujin Onsen: Bathing in the Dragon God's Gift
Located in the mountainous Kii Peninsula, along the upper reaches of the Hidaka River, lies the ancient onsen village of Ryujin Onsen, with a history spanning over a millennium. Legend has it that the Dragon God appeared in a dream to the Buddhist monk Kukai, revealing the presence of the hot springs. Its clear, slightly alkaline sodium bicarbonate salt spring is a draw for onsen enthusiasts from far and wide.
For a truly immersive experience, spend a night at Shimo-goten, a former villa of the Tokugawa Shogunate dating back to 1639. The traditional Japanese rooms offer stunning views of the Hidaka River and surrounding mountains. The onsen facilities include traditional indoor baths and a unique "zashiki-buro," where the changing room and bathing area are covered in tatami mats. The outdoor rotenburo, a mixed-gender bath where swimwear is required, provides breathtaking views of the river valley (availability depends on river levels). While more expensive than Kawachu Onsen, the unique history and luxurious ambiance of Shimo-goten make it a worthwhile splurge.

| Accommodation | Shimo-goten (Former Tokugawa Villa) |

These three experiences offer a glimpse into the diverse and captivating world of Japanese onsen culture.

So, pack your bags and prepare to be enchanted by the beauty and warmth of Japan's hot spring wonders!
