According to kuden (oral instruction), the actor who plays the role of Enya Hangan must return home immediately after the play ends, without seeing or speaking to other people (this instruction was observed during the Edo period).
また、塩冶判官役にも口伝があり、出が終わった後には誰にも顔を合わせず口をきかず、すぐに家に帰らなければならない（江戸時代ではこれが守られていた）。
