Is there a limit in the number of characters for a general-use JP domain name label?
• A General-use JP domain name containing Kanji, Hiragana, and/or Katakana must consist of one to fifteen (1~15) characters, excluding “.JP” suffix. The number of characters in an ASCII JP domain name must be from three to sixty-three (3~63). Please note that if ASCII, Kanji, Hiragana and/or Katakana characters coexist in a same label of a General-use JP domain name, each character will be counted as one, whether or not it is of double byte code or single byte code.
