Though 'heika' (His Imperial Majesty) is used as the title of honor for the emperor (prescribed by Imperial House Act) as with kings and queens of foreign countries, the expression of Kinjo Tenno Heika is not used and the emperor is only called Kinjo Heika, Tenno Heika or Heika, or Mikado which is rarely used now.
天皇の敬称は、諸外国の国王・女王と同様に「陛下」が使われている（皇室典範で規定）が、今上天皇陛下とは言わず、今上陛下、天皇陛下もしくは陛下、現在では殆ど使われていないが帝（みかど）とのみ呼ばれる。
