For those who are self-conscious about being nude in public, Hakone Kowakien Yunessun is a fitting alternative. In addition to twenty kinds of Hakone hot springs, spas and open-air baths, the site also features an area in which bathing suits are allowed.

Popular among overseas visitors are the “Wine Bath,” “Coffee Bath,” “Doctor Fish Footbath,” “Rodeo Mountain,” and “Outdoor Hot Spring With Scenic View Bath.” As the names suggest, "Wine Bath" and "Real Coffee Bath" use real wine and coffee.

Wine baths relax your mind and body with the scent of rich wine and are good for the skin. For families traveling together, children are also allowed in the wine bath.

In "Doctor Fish Footbath", small fish gently nibble at your feet for a pleasant tickling sensation. Sessions cost 300 yen but business hours vary, so check in advance.

Rodeo Mountain is a popular water slide with hot water rapids. Guests over 110cm can ride all three slides and conquer the mountain.

At 40 meters in length, the Outdoor Hot Spring With Scenic View Bath offers a breathtaking panoramic view of Hakone’s rich natural beauty. It’s highly recommended for anyone who wants to enjoy authentic Hakone hot springs, and the whole experience is great for washing away fatigue.

Hakone Kowakien Yunessun has swimwear rentals and guests with tattoos can enter if their tattoos are covered, making it a foreigner-friendly facility.

Hakone Yuryo is a stunning onsen that offers an authentic Japanese-style bathing experience. It's an ideal place to enjoy the finest bathing experience that Hakone has to offer. The facility boasts 19 private outdoor baths, which are surrounded by lush forests, making it the largest of its kind in the area. You can relax, unwind, and spend quality time with your family or friends without worrying about prying eyes.

You can reserve private single-room open-air baths up to a month in advance, but if there are open spots available on the day of your visit, you can book them then. Hakone Yuryo is a great place to rest your mind and body and give yourself a well-deserved break.

In addition to forming a beautiful memory of your travels in Japan, these relaxing Hakone onsen baths are also a great place to plan the next leg of your trip. Hakone Yuryo has three room sizes, so you’re sure to find one that fits the size of your group.

All room types are peaceful and modern, and you won’t want to leave!

In addition to the private single-room open-air baths, there’s also a large public bath called Hondon Yurakun Oyu. Loyly is a traditional Finnish sauna bathing method in which steam is generated by pouring aromatic water over the sauna stones.

In a loyly sauna, guests are fanned with a large fan by a master. The hot steam causes sweating, which is believed to improve metabolism. This experience is popular among sauna enthusiasts and those seeking health and beauty benefits.

The steam is produced by water that includes a variety of aromas, such as grapefruit, mint, lime, chamomile, wine, peach, lavender, eucalyptus, and bergamot. The aromas change depending on the season and time, so you can enjoy different scents whenever you visit.

Loyly is also suitable for people who don't usually enjoy saunas. It's not too taxing on the body, as the temperature is only 80 degrees Celsius, and the humidity levels are lower.

After enjoying the Löyly, we recommend visiting the "Hogushian Yururuka" relaxation area for a thorough body maintenance session. They offer a variety of courses that combine unique techniques with reflexology, lymphatic treatments, and stretching, ensuring you'll find the perfect course to address your individual needs.

If you don't have time for a full relaxation session but still want a quick treatment, consider the special "Hogushidokoro Yururuka" relaxation area. They offer courses such as head massages, foot massages, aromatherapy treatments, and facials.

Lastly, you can enjoy a striking view of Mount Fuji from the shores of Lake Ashi while relaxing at the Ryuguden Main Building. Originally built nearly 80 years ago and renovated in 2017, this impressive hotel resembles the Byodo-in temple in Uji, Kyoto, and is also registered as a Japanese cultural property.

Ryuguden’s best feature is the view of the Hakone rim, Lake Ashi, and Mt. Fuji, visible from all the baths. The facility is popular with both local and overseas tourists.

The men’s indoor bath affords visitors a simultaneous view of Lake Ashi and Mt. Fuji. At the same time, a similar vista can be appreciated from the women’s outdoor bath, along with the refreshing breeze!

On days with clear weather, you can enjoy a breathtaking view of Mt. Fuji and the reflection of the sky and clouds in Lake Ashi. Even on days with less than perfect weather, when Mt. Fuji is not visible, you can still appreciate the splendor of the lake.

The hot spring contains calcium, sodium, sulfate, and chloride, which are said to be effective for neuralgia, muscle pain, and joint pain. It's perfect for soothing your tired body after exploring Hakone's popular spots.

When you visit Ryuguden Main Building, don't miss dining at the restaurant "Fuji." They offer meals like the Yudofu Gozen Set and the Tempura & Soba Set (4,900 yen on weekdays, 5,200 yen on weekends and public holidays).

The "Yudofu Gozen" set also comes with a convenient package that includes the bath fee. If you plan to have lunch, be sure to check at the front desk for this offer.

Each of these hot springs offers unique features, so if you’re wondering where to go in Hakone, give one of them a try!
