[Case Study] Metos Co., Ltd. Pre-introduces "Outdoor Metos Private Sauna" to Unzen Kyushu Hotel's "Unzen-tei Hanare"

Metos Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director: Shoichiro Yoshinaga; hereinafter "Metos"), which develops hot bath/sauna, fireplace/wood stove, and welfare businesses under the motto "warming people's minds and bodies," has introduced its newly developed "Outdoor Metos Private Sauna" to the "Unzen-tei Hanare" (premium rooms) of Unzen Kyushu Hotel (Unzen City, Nagasaki Prefecture), which was renovated on April 25, 2026. "Unzen Kyushu Hotel" is a resort hotel owned and managed by PROSPER Japan Enterprise Growth Support Fund No. 1 Investment Limited Partnership. **Launch of "Outdoor Metos Private Sauna"** We received numerous requests for outdoor installation, such as on terraces, for our indoor "Metos Private Sauna," and have now newly developed an "outdoor type." This latest model sauna, which will be available from fiscal year 2026, has been introduced to the private terraces of the "Unzen-tei Hanare" (all 4 rooms), the highest-grade guest rooms closest to the steaming Unzen Hell. A unique charm of the outdoor type is that the natural outdoor air that spreads the moment you step out of the sauna room significantly enhances the quality of hot and cold bathing. Especially, the clear air of Unzen and the environment surrounded by rich greenery gently cools the heated body, bringing a deep sense of liberation and high refreshment. You can enjoy a special "totonoi" (state of deep relaxation) experience unique to Unzen, which cannot be found in urban saunas, feeling integrated with nature. **Authentic Finnish Sauna and Self-Löyly** "Unzen-tei Hanare" offers self-löyly, and aroma oils (rento) for löyly are also available. The comfortable steam and aroma envelop the whole body, allowing guests to enjoy a luxurious sauna experience at their own pace without any hesitation. Metos quickly started sauna construction and sales in cooperation with overseas partner companies, triggered by the creation of a sauna in the athletes' village of the 1964 Tokyo Olympics. The Metos Private Sauna is a compact condensation of the experience and charm of facility/commercial public saunas. The interior and heater are all "Made in Japan" units. This outdoor Metos Private Sauna will be sequentially introduced for general household use. **A Wellness Space for Complete Relaxation in the Guest Room** In addition to the sauna, the terrace is equipped with a private cold bath and an outdoor air bathing sofa. While retaining the existing cloudy natural hot springs (indoor and outdoor baths), a completely private healing space has been realized where guests can complete their hot spring, sauna, cold bath, and outdoor air bathing experience within the guest room. Guests can enjoy a blissful outdoor air bathing space on the terrace while feeling the rich nature of Unzen up close. **Facility Overview** Facility Name: Unzen Kyushu Hotel Location: 320 Unzen, Obamacho, Unzen City, Nagasaki Prefecture 854-0697 Room Name: Unzen-tei Hanare Number of Rooms: 4 rooms Capacity: 4 people Homepage: https://kyushuhtl.co.jp **About Metos' Hot Bath and Sauna Business** Triggered by the creation of a sauna in the athletes' village of the 1964 Tokyo Olympics, we quickly started sauna construction and sales in cooperation with overseas partner companies.
