Sauna Heaven

Located in the city of Soka in Saitama, Sauna Heaven is the place to go for its exceptional aufguss service. The sauna cabin looks like a human cat tower, full of steps and nooks covered in soft rugs, with even a small secluded seating area equipped with its own kiuas (stove). Every thirty minutes to an hour, the staff orchestrates an aufguss service that plays out like an olfactory DJ set, using essential oils, fruit peels and even ice. They fan towels to circulate the airflow and send focused blasts of heat to those in attendance. People clap when it’s over, and for good reason. One thing to note is the outdoor rest area, which is the only part of the facility that requires a bathing suit (available to rent if you forget one).
