Wabun code (和文モールス符号,wabun mōrusu fugō; Morse code for Japanese text) is a form ofMorse code used to sendJapanese language inkana characters.^[1] UnlikeInternational Morse Code, which represents letters of theLatin script, in Wabun each symbol represents a Japanesekana.^[2] For this reason,Wabun code is also sometimes calledKana code.^[3]

When Wabun code is intermixed with International Morse code, theprosignDO ( ▄▄▄ ▄ ▄ ▄▄▄ ▄▄▄ ▄▄▄ ) is used to announce the beginning of Wabun, and the prosignSN ( ▄ ▄ ▄ ▄▄▄ ▄ ) is used to announce the return to International Code.
