Japan is famous for many things—sushi, cherry blossoms, and Mount Fuji—but one of its most timeless treasures is the onsen (hot spring). These natural baths are a key part of Japanese culture and wellness, offering relaxation, healing, and a connection to nature. If you’re planning a trip and want to experience true tranquility, visiting traditional onsen towns in Japan is a must. In 2025, these towns are more welcoming than ever, blending ancient customs with modern comforts.
Here are some of the best traditional onsen towns in Japan to add to your 2025 travel list.
1. Kusatsu Onsen (Gunma Prefecture)
Why visit: High-quality water, rich history, and dramatic hot spring displays
Kusatsu Onsen is often considered one of Japan’s top three onsen destinations. Nestled in the mountains of Gunma Prefecture, this charming town is known for its Yubatake—a large hot water field in the center of town where steaming mineral water cascades over wooden channels.
The water here is said to cure everything but heartbreak, and its high acidity makes it one of the most therapeutic in the country. In 2025, Kusatsu is adding eco-conscious ryokan upgrades, making it a great mix of tradition and sustainability.
Don’t miss: Yumomi performance (traditional method of cooling hot spring water), a soak at Sainokawara Rotenburo (a massive open-air bath surrounded by nature).
2. Kinosaki Onsen (Hyogo Prefecture)
Why visit: Seven public bathhouses, charming willow-lined streets, yukata culture
Kinosaki Onsen is the perfect introduction to onsen town culture. With seven unique public bathhouses, visitors walk from one to another in wooden geta sandals and colorful yukata robes—a centuries-old custom that makes the entire town feel like a living museum.
What sets Kinosaki apart is its accessibility and warm hospitality. The town is easy to navigate, and most ryokans offer free access to the public baths. It’s also a great place to try tajima beef, a local delicacy and cousin to Kobe beef.
Don’t miss: Bath-hopping with a yukata pass, strolling along the canal in the evening, and riding the Kinosaki Ropeway for scenic views.
3. Beppu Onsen (Oita Prefecture, Kyushu)
Why visit: Diverse bathing experiences, geothermal wonders, family-friendly
Beppu Onsen is one of Japan’s most famous hot spring areas, producing more hot spring water than anywhere else in the country. It’s divided into eight major hot spring districts, offering a wide variety of experiences: mud baths, sand baths, steam baths, and more.
In 2025, Beppu continues to invest in eco-tourism and international-friendly signage, making it a top pick for first-time visitors. It’s also home to the “Hells of Beppu”, a series of colorful hot springs for viewing (not bathing) that showcase nature’s wild side.
Don’t miss: Sand baths at Beppu Beach Sand Bath, the steaming Blue Hell (Umi Jigoku), and the funky mud baths of Myoban Onsen.
4. Yufuin Onsen (Oita Prefecture, Kyushu)
Why visit: Scenic views, art culture, romantic atmosphere
Just a short train ride from Beppu, Yufuin is a quieter, more refined onsen town. Set against the backdrop of Mount Yufu, this town blends traditional bathing culture with an artsy, boutique vibe. You’ll find cozy cafés, galleries, and locally made crafts around every corner.
Yufuin’s hot springs are mild and skin-friendly, ideal for those looking for a gentle, rejuvenating soak. It’s especially popular among couples and solo travelers looking for peaceful wellness retreats.
Don’t miss: Morning walks along Yunotsubo Street, Lake Kinrinko at sunrise, and art galleries like the Yufuin Floral Village.
5. Noboribetsu Onsen (Hokkaido)
Why visit: Volcanic landscapes, powerful mineral baths, northern wilderness
Located in the northern island of Hokkaido, Noboribetsu Onsen is famous for its strong volcanic activity and healing waters. It offers nine different types of mineral-rich hot springs, making it a go-to destination for those seeking relief from fatigue or skin issues.
What makes this town special is Jigokudani (Hell Valley)—a dramatic, otherworldly landscape of steaming vents and sulfurous craters. Even if you’re not soaking, the trails and scenic views here are unforgettable.
Don’t miss: Dai-ichi Takimotokan’s massive indoor/outdoor baths, walking through Hell Valley, and sampling Hokkaido’s seafood specialties.
