The Tokyo Waterworks Museum, which opened in 1995, is a facility that promotes the history and culture of Tokyo's waterworks from the Edo period to the modern and contemporary eras. It consists of three floors: <1F History of Modern Waterworks>, <2F History of Edo Waterworks>, and <3F Library and Lecture Hall>, with the 1st and 3rd floors being the main areas that have been renovated. In addition to renovating displays space, efforts have been made to broaden the scope of facility operations, such as creating a library of video materials and introducing audio guides (in four languages: Japanese, English, Korean, and Chinese). Furthermore, having been entrusted with the operation of the museum after its reopening, the museum has expanded its operations to include displays by attendants (in Japanese and English), holding special exhibitions and events, and introducing AR guided tours, thereby promoting the waterworks business.
