And Hanamichi, the passage running through the audience on which Kabuki actors enter on and depart, provides the audience with the two-dimensional image (or depth) that cannot be experienced in other kinds of theater, and "seri" (a trapdoor) & "chunori" (a flight on wires from the stage over the heads of the audience) provide the audience with the three-dimensional image (or the height), thereby upgrading Kabuki to the higher level of theater.
また、客席を貫いて歌舞伎役者が登場・退場する花道によって他の演劇には見られないような2次元性（奥行き）を、またセリと宙乗りにより3次元性（高さ）を獲得し、高度な演劇へと進化した。
