THE KUKUNA is a resort and spa on the north shore of Lake Kawaguchi in Asakawa, where all 65 guest rooms are oriented toward Mount Fuji across the lake. The property's signature feature is Ozora-no-Yu, a panoramic top-floor bathing area including an infinity-edge open-air pool-style bath called Tsuki that appears to merge with the lake and mountain view beyond. Dining draws on an in-house winery, The 997 Katsunuma, opened in Katsunuma in 2022, which supplies wine paired with creative cuisine built around Yamanashi ingredients at the hotel's restaurants. Beyond the headline bath, the resort includes a dry sauna, a mist sauna, a karaoke lounge, a tea lounge, and a beauty salon, giving it a fuller resort-spa program than most Kawaguchiko onsen ryokan. Room categories range from Japanese-Western hybrid layouts to suites and rooms with private open-air baths. There is no dedicated fitness room. The Asakawa location keeps the resort close to Oishi Park's lavender fields and the quieter western stretch of the lake, away from the busier Funatsu and Kawaguchiko Station area.
