A public bath is a building that provides swimming pools and bathing facilities, historically serving as a main source of hygiene in urban areas. Although commonly referred to as “public,” access has often been limited by gender, religion, or social status. In addition to their hygienic function, these spaces have acted as centers for social interaction, including saunas, massages, and relaxation treatments.
Writers such as Jukichi Inouye emphasized their role in supporting the poor, while Edward Sylvester Morse compared Japan’s widespread public baths to their limited presence in the West. Mohandas K. Gandhi pointed out their affordability, highlighting their practical nature. As private bathrooms became more common, public baths moved toward recreational use, yet their role as places of community engagement remains, reflecting changing societal needs and cultural traditions.
