Wabun code

LanguageTemplate:Pluralize from text	Japanese (basic support)
Classification	non-Latin Morse code for Kana
Succeeded by	JIS C 0803 (JIS X 6001), JIS C 6220 (JIS X 0201)

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.
