Opened in April 2020 in Tokyo's Takeshiba area, "mesm Tokyo, Autograph Collection" (hereafter, mesm Tokyo) is a luxury hotel. The "Autograph Collection" in the hotel's name refers to a collection by Marriott International, bestowed only upon unique hotels recognized for their distinct design, hospitality, and individuality. One such distinctive feature is that every one of the 265 guest rooms is equipped with CASIO's digital piano, "Privia PX-S1000." In this series, we invite promising creators to the hotel to share the appeal of Privia x mesm Tokyo as they experience it.
