Tourists from overseas account for half of the participants on some days. Yuki Mori, an associate professor of the Urasenke School of Tea Ceremony, said the event originally started to encourage people to enjoy "the empty tourist spot." With overtourism being such a significant headache across Japan, Mori said the program seems to fit the current trend of dispersing tourists over different hours of the day. A growing number of municipalities are trying to promote morning and evening sightseeing events to ease daytime congestion.
