When you think of onsen (hot springs) in Japan, snowy mountains and winter getaways might come to mind. But here’s a secret: many of Japan’s most beautiful onsen resorts are just as magical—if not better—in summer. From breezy mountain villages to forest-view ryokan and private outdoor baths, these summer spa retreats offer the perfect mix of refreshment, relaxation, and natural beauty.
Whether you’re escaping the city heat or capping off a busy sightseeing trip, here are our top picks for cool onsen and ryokan experiences—all with private car transfers available for a stress-free journey.
Hakone – Classic Onsen with Forest Views
Approx. 1.5–2 hrs from Tokyo
Hakone is one of Japan’s most accessible and iconic onsen towns, and it’s surprisingly comfortable in the warmer months. Many ryokan feature open-air baths shaded by trees, and the mountain air stays several degrees cooler than central Tokyo.
Why it’s great in summer:
Hydrangeas bloom along the Hakone Tozan Railway, cool mist rolls in over Lake Ashi, and you can unwind in a bath surrounded by greenery and birdsong.
Try:
- Gora Kadan: A luxury ryokan set in nature with top-tier service and seasonal kaiseki meals.
- Yamanochaya: A traditional option with riverside rotenburo (outdoor baths) and natural ambiance.
Mt. Fuji Area – Open-Air Baths with Fuji Views
Approx. 2–2.5 hrs from Tokyo
The Mt. Fuji region, especially around Lake Kawaguchi, offers stunning views and crisp summer air. Many onsen here take full advantage of the landscape, with panoramic views of Mt. Fuji from open-air baths—particularly magical during early mornings or sunset.
Why it’s great in summer:
Clear skies and warm weather mean better Fuji visibility, plus options like cold baths, herbal foot soaks, and nearby lavender fields in July.
Try:
- Fujikawaguchiko Onsen Konanso: Spacious rooms and rooftop baths facing Mt. Fuji.
- Shuhokaku Kogetsu: A peaceful lakeside retreat with Fuji-facing onsen and seasonal cuisine.
Izu Peninsula – Coastal Breezes & Oceanview Onsen
Approx. 2.5–3 hrs from Tokyo
If you love the sea, Izu’s hot spring towns like Atami, Ito, and Shimoda offer the best of both worlds: coastal scenery and rejuvenating mineral-rich waters. Many hotels and ryokan have rooftop baths overlooking the ocean, plus cool sea breezes to beat the heat.
Why it’s great in summer:
Enjoy cool evenings by the sea, beach walks, and open-air onsen with dramatic sunset views.
Try:
- ATAMI Sekaie: A modern seaside ryokan with private open-air tubs and sleek design.
- Hanafubuki (Ito): Nestled in a forest near Jogasaki Coast, this ryokan has seven unique private baths to choose from.
Kinosaki Onsen – Stroll, Soak, Repeat
Approx. 2.5 hrs from Kyoto or Osaka
This charming town in Hyogo Prefecture is famous for its “onsen-hopping” culture—where you stroll the streets in a yukata, visiting multiple public baths throughout the day. Summer brings colorful yukata rentals, cool riverside paths, and even firefly sightings.
Why it’s great in summer:
The vibe is festive yet relaxed, and many inns offer cold bath options, shaded gardens, and breezy rooms with river views.
Try:
- Nishimuraya Honkan: A luxurious ryokan with historic charm, fine dining, and private baths.
- Tsubakino Ryokan: Great for families and couples looking for casual comfort and good food.
Nozawa Onsen – Mountain Village Charm & Alpine Air
Approx. 3.5–4 hrs from Tokyo
Tucked into the Nagano mountains, Nozawa Onsen is a cool, quiet getaway in summer. Best known for winter sports, the town transforms into a peaceful retreat with alpine flowers, local festivals, and free public baths throughout the village.
Why it’s great in summer:
It’s noticeably cooler than the city, with crisp air and stunning mountain views. Explore quiet trails, relax in outdoor baths, and sip on cold sake at a local izakaya.
Try:
- Ryokan Sakaya: Elegant, centrally located, and known for its beautiful baths.
- Nozawa Grand Hotel: Features an open-air onsen with panoramic forest views.
