A Japanese-style lounge, 'Yuzuki', delivering the joy of being loved. Entrust your heart for a special time of healing.
'Yuzuki' is a Japanese-style concept lounge providing a simulated experience of being lovers, heart-fluttering moments, and sweet healing. Born as a sister shop to 'Mitsugetsu', this is a fantastical Japanese mansion. Cast members in kimonos provide a special experience, as if you have wandered into a bygone era.

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 security of being protected. [Menu] 'Sleeping Together' 'Bud': Conversation and light physical contact. 'Flower Mist': Kisses to full-body caressing. 'Once-in-a-Lifetime': A special course with content varying by room. Guests change into yukata upon entry. Changes are possible mid-stay. The cast lives together in a dormitory on the 2nd floor of the mansion.
