Japanese-style lounge 'Yuzuki' delivers the joy of being loved. A special time to entrust your heart and be healed.
Japanese-style concept lounge 'Yuzuki' provides a simulated experience of being a lover, excitement, healing, and sweet moments. Born as a sister establishment to 'Mitsugetsu,' this is a fantastical Japanese mansion. Cast members in kimonos provide a special time that feels like wandering into a bygone era. If 'Mitsugetsu' is a love that steals and toys with the heart, 'Yuzuki' is a love where you entrust your heart and are cherished.

Shadow Room (Aoma, Shigure): A quiet love touching their true faces. Sun Room (Hinata, Riku): The happiness of being pampered and warmth. Moon Room (Shido, Eito): The sense of security in being protected. [Menu] 'Sleeping Together' 'Bud': Time to enjoy conversation and physical contact. 'Flower Mist': Special intimate time. 'Once-in-a-Lifetime': A special course with content varying by room. Upon entry, guests change into yukata. Changes are possible mid-stay.
