in addition to its design with a circular outline , mitsuba-aoi includes designs with angular outlines (moriyama mitsu-aoi , saijo mitsu-aoi , etc .) and gokan (五環 ) (five aoi-mon arranged in a circular pattern ). 外郭が丸（輪）であるもののほかに、隅切り角（守山三つ葵・西条三つ葵など）のものや五環であるものもそういう。
another characteristic of noh is that performers move in a circular pattern on a square stage in consideration for audiences on three sides , while kabuki (traditional japanese drama performed by male actors ) and classical japanese dance derived from kabuki are performed on a rectangular stage on the premise for showing the performance to audiences in the front . また能は、歌舞伎やそこから発生した日本舞踏が横長の舞台において正面の客に向って舞踏を見せることを前提とするのに対して、正方形の舞台の上で三方からの観客を意識しながら、円を描くようにして動く点にも特徴がある。
