<p><b>JADE</b> was the <a href="Codename" class="mw-redirect" title="Codename">codename</a> given by US codebreakers to a Japanese <a href="World_War_II" title="World War II">World War II</a> cipher machine. The <a href="Imperial_Japanese_Navy" title="Imperial Japanese Navy">Imperial Japanese Navy</a> used the machine for communications from late 1942 until 1944. JADE was similar to another cipher machine, CORAL, with the main difference that JADE was used to encipher messages in <a href="Katakana" title="Katakana">katakana</a> using an alphabet of 50 symbols.<sup id="cite_ref-NSAearlyjapanese_1-0" class="reference"><a href="#cite_note-NSAearlyjapanese-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
</p><p>According to the NSA, "apparently, the JADE machine did not stand up to heavy usage in the field, and, after an initial high volume of traffic, it was used much less." While CORAL traffic was also low, an important user was a Japanese representative, Vice Admiral Abe, to an Axis war-planning council whose reports coded in CORAL were intercepted and proved vital to Allied planning in the European theater.<sup id="cite_ref-NSAearlyjapanese_1-1" class="reference"><a href="#cite_note-NSAearlyjapanese-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
