Recently, It has become common for physical fitness center which are gradually becoming larger and luxurious to provide bathhouse business facilities and equipment for the convenience of users. Accordingly, there is a question whether bathhouse business facilities and equipment installed additionally in the physical fitness center corresponds to the ‘bathhouse business’ fall under the 「The Public Health Control Act」. In response, the Supreme Court ruled that the bathhouse business facilities and equipment related to bathing and sweating that were installed in the places attached to the sports facilities belong to the ‘bathhouse business’ that had the reporting duty set by 「The Public Health Control Act」. The Supreme Court’s judgment seems reasonable in terms of the grammatical interpretation, but it is problematic that do not reflect the reality of the physical fitness center today and there is a possibility that judgment is misinterpreted to the related industry and business operators. Thus, this paper proposed a method to clarify the concepts of bathing and bathhouse business , which are currently defined and interpreted unclearly, and suggested a way to add bath related facilities installed additionally in the physical fitness center to facilities that are excluded from the bathhouse business of 「The Public Health Control Act」 through revision of 「The Public Health Control Act」. Finally, we proposed a measure that prepare separate safety and hygiene standards for physical fitness centers in the Sport Facilities Act in order to provide safety and hygiene management of bath related facilities in this paper.
