The person who wants to receive this service first draws Omikuji (sacred lots) to pick up a number from one to three, then stands in front of Torii (an archway to a shrine), where, for example, if the number is two, then he or she records the appearance and other things of the second passer-by.
まず御籤で1～3の数字を出し、鳥居の前に立って、例えば御籤で2が出れば2番目に通った人の姿などを記録する。
