Basically, kabuki actors should be called by yago, not by myoseki ('yago' is substitute name which actor calls himself; in the Edo period kabuki actors were not allowed to use their surnames, so they used yago; 'myoseki' is a successive name); therefore, the twelfth Danjuro ICHIKAWA (myoseki) should not be called 'Ichikawa-san' nor 'Danjuro-san' ('san' means 'Mr.'), he should be called 'Narita-ya-san' ('Narita-ya' is his yago).
そもそも歌舞伎役者は姓名ではなく屋号で呼びかけるのが礼儀（「市川さん」｢團十郎さん」ではなく、｢成田屋さん」と呼ぶ）。
