Matsumoto Kōshirō
Danjūrō, like other actors' names, is bestowed (or given up) at grand naming ceremonies called "shūmei" in which a number of actors formally change their names. The name Danjūrō is generally taken at the peak of an actor's career; another name may be taken after retirement. Prior to taking the name Danjūrō, an actor frequently had the names Matsumoto Kōshirō, Ichikawa Shinnosuke, or Ichikawa Ebizō.
