"The Three Mystic Apes" (Sambiki Saru) were described as "the attendants of Saruta Hito no Mikoto or Kōshin, the God of the Roads". The Kōshin festival was held on the 60th day of the calendar. It has been suggested that during the Kōshin festival, according to old beliefs, one's bad deeds might be reported to heaven "unless avoidance actions were taken…". It has been theorized that the three Mystic Apes, Not Seeing, Hearing, or Speaking, may have been the "things that one has done wrong in the last 59 days".
