The other day, I held a beautiful pink booklet in hand and saw people walking around Nihonbashi. I was worried, and I picked up the booklet. Apparently, it turned out that they are participating in the town excursion-type real treasure hunting event "Nihonbashi treasure hunt phantom cherry blossoms-a hanging from people-".
Recently, it seems that various events have been held that combine "walking around the city" and " solving the mystery".
