When plays on the same program are performed for days, the three days of shonichi (the first day), nakabi (the middle day) and senshuraku (the final day) are considered to be the most important ones, and it is customary that the performers visit each other at their respective backstage rooms and pay their compliments to each other.
興行の中で、初日・中日（なかび）・千秋楽の3日が特に重要な日として考えられており、出演者が互いに楽屋を訪れ挨拶するなどの習慣がある。
