Hakone Kowakien Yunessun (箱根小涌園ユネッサン) stands out as Japan's most innovative hot spring theme park, redefining traditional onsen culture with a perfect blend of entertainment and relaxation. This unique facility in scenic Hakone seamlessly merges the playful with the traditional across two distinct zones: Yunessun – where swimsuit-clad visitors enjoy whimsical themed baths like wine, coffee, and green tea – and Mori no Yu, offering authentic naked bathing in tranquil, mineral-rich waters. For tattooed travelers often limited in their onsen options, Yunessun provides a welcoming alternative with its covered tattoo policy and family-friendly atmosphere. Perched 600 meters above sea level with panoramic views of Sagami Bay and Hakone's lush mountains, this resort complex offers both the cultural authenticity and Instagram-worthy experiences that modern travelers seek.
Covered Tattoos Permitted: Both Yunessun and Mori no Yu areas allow guests with tattoos as long as they're covered with waterproof bandages or tattoo sleeves. For complete freedom, private baths at Mori no Yu can be reserved for an additional fee, allowing unrestricted tattoo visibility in a secluded setting.
- Unique Themed Baths: Immerse yourself in wine, coffee, and green tea baths with ceremonial "pourings" throughout the day
- Family-Friendly Environment: One of few onsen experiences where the whole family can enjoy together, with heated water slides and play areas
- Dual Bathing Experiences: Enjoy both traditional naked bathing (Mori no Yu) and swimsuit areas (Yunessun) in a single visit
- Perfect for Tattoo Concerns: Provides options for all comfort levels with both covered-tattoo public baths and private rental baths
- Spectacular Mountain Setting: Open-air baths with sweeping views of Hakone's natural landscape and Sagami Bay
- Year-Round Appeal: Heated indoor and outdoor facilities make it enjoyable regardless of season or weather
Onsen Facilities & Amenities
Bathing Experience & Onsen Etiquette
At Yunessun, the playful "Swimsuit Zone" invites you to hop between themed baths ranging from 37-40°C while fully clothed in swimwear. The signature wine bath, inspired by Cleopatra's beauty regimen, features actual red wine poured several times daily, while the coffee bath brewed using traditional Nel Drip methods promises skin-beautifying antioxidants. Children delight in the 40-meter "Doctor Fish" flowing pool and heated water slides maintained at comfortable temperatures year-round. For a more authentic experience, Mori no Yu's alkaline-rich waters (pH 8.5) soothe tired muscles and improve circulation as you soak in elegant granite and cypress wood baths. The outdoor rotenburo presents the quintessential Japanese bathing experience—soaking beneath open skies surrounded by seasonal foliage with mountain panoramas stretching to Sagami Bay. The mineral composition, particularly rich in sodium chloride and calcium, is said to relieve nerve pain, improve skin conditions, and enhance overall well-being.
