As Nyobon (sexual indulgence) is a sin for Buddhist monks, some infidel monks went to play at Yoshihara yukaku (red-light district) pretending to be a doctor or a master of haiku (a Japanese poem in seventeen syllables having a 5-7-5 syllabic form and traditionally containing a reference to the seasons).
僧侶の女犯は罪であったため、不真面目な僧侶などは医者や俳句の師匠の振りをして吉原遊廓に出向きなどもした。
