Isetan has released the full promotional video for its official song, "ISETAN-TAN-TAN," on YouTube. The song was released by Akiko Yano, a self-proclaimed Isetan fan, in October of last year to coincide with the launch of Isetan's new tartan check pattern, "Macmillan/Isetan." Upon hearing the song, employees expressed a desire to dance, saying, "The moment I heard the intro, I couldn't help but want to express my gratitude to Akiko Yano for creating the song," and this led to the launch of the dance project. An internal call for participants was made, and more than 500 staff members from Japan and overseas volunteered, far exceeding initial expectations. In keeping with Isetan's desire to "do it thoroughly," the choreography was commissioned from MIKIKO, who directs and choreographs Perfume's live performances. In addition to a relatively easy version that all employees could dance, they were also asked to create a professional-quality version. The choreography involves overlapping the fingers of both hands to create a tartan pattern, and the entire video expresses the desire for everyone to enjoy shopping at Isetan.

The PV was filmed inside the Isetan Shinjuku store. Filming took place over two full days, utilizing the store's closed days. At the end of the PV, the Isetan dancers gather on the central street on the first floor of the main building, and deliver a spectacular performance. Akiko Yano herself also makes a surprise appearance on the day of filming.

The PV will be screened on a large projector above Prada in front of the central street on the first floor at 15 and 45 minutes past the hour during store hours. It will also be used as in-store music.
