A documentary-style program closely following a family-run public bathhouse. The father passionately dedicates himself to preserving the nostalgic Showa-era bath experience. Meanwhile, his daughter serves as a "bath girl," naturally undressing in front of guests and performing body washes, showcasing the traditional essence of an old-fashioned bathhouse. Their actions are not driven by indecency, but by meticulous care and technique aimed at cleansing guests' bodies. Intimate cleansing methods include oil rubbing using bare skin, oral suction to remove impurities, and internal vaginal washing with rods—various rituals performed by the father and daughter together. This film captures their daily lives as they work side by side, sharing their passion and unique traditions.
