In the Edo Period (1603-1868 ) people didn't have baths at home, and public bath houses were built to meet the need. There were about 600 in Edo. At first they were steam baths, then large bathtubs were developed. As all were naked and people co-mingled without regard for age, gender, or rank, the bath house was an egalitarian place. Apparently another popular item was a scented lotion made with floral essences distilled using a still known as a ranbiki. This fragrance has the warmth and glow of the moment you step out of the bath.
