Haimyo (俳名)
Haimyo is originally synonymous with Haigo (the pen name of a haiku poet), but it was used as follows in the field of public entertainment after the mid Edo period:
1. a name (pseudonym) freely used by kabuki actors both in public and private matters, apart from their family name which they used on the stage (stage name)
2. a term equivalent to what is called a stage name today, derived from the definition 1 above
