Wabun code

Template:Short description Template:Use dmy dates Template:Infobox character encoding is a form of Morse code used to send Japanese language in kana characters. Unlike International Morse Code, which represents letters of the Latin script, in Wabun each symbol represents a Japanese kana. For this reason, Wabun code is also sometimes called Kana code.

When Wabun code is intermixed with International Morse code, the prosign DO (Template:Morse) is used to announce the beginning of Wabun, and the prosign SN (Template:Morse) is used to announce the return to International Code.
