Wabun code

The Wabun Code (和文モールス符号, wabun mōrusu fugō, Japanese text in Morse code) is a form of Morse code used to send Japanese text. Unlike International Morse Code, which represents letters of the Roman alphabet, 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/ (-..---) is used to announce the beginning of Wabun, and the prosign SN/ (...-.) is used to return to International Code.

Wabun Code was famously used to transmit the message "NIITAKA-YAMA NOBORE" on December 2, 1941, signalling the go-ahead of the Japanese attack on Pearl Harbor.
