SAUNAXX 目黒駅前店

SAUNAXX 目黒駅前店 offers private sauna rooms, but staff were required for reservation management and key handover, limiting operating hours. Privacy-conscious users were also requesting contactless service.

KEYVOX smart locks were installed in each private room, making the entire process from reservation to entry and exit fully self-service. Users book and pay online, then enter their room with a QR code. Cleaning management is also linked to entry and exit logs.

24-hour operations were achieved, with late-night and early-morning usage accounting for 30% of total use. The staff-free private spaces are highly popular, achieving an 80% repeat rate. Operating costs were reduced by 40% while revenue doubled.
