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 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 (-..—) 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 12 08” (新高山登れ12 08?) or “Climb Mount Niitaka” on December 2, 1941, signalling the go-ahead of the Japanese attack on Pearl Harbor.[1]
