HayaKuchi - Mini Japanese IME by HayaKuchi Dev

HayaKuchi is a Japanese Input Method Editor extension which tries to process your inputs and transform it automatically in order to write in Japanese, even if you are using an alphabetical keyboard layout.

In order to do so, HayaKuchi will highlight the last word you inputted and simulate a copy-paste which will replace your input with the corresponding hiraganas and katakanas. You will also be able to query a dictionary in order to replace your current input with any similar words that can be found.

HayaKuchi is also able to convert directly your characters to half-width or full-width, which may be useful on some websites that will accept one or the other.

If you have the time to do so, please review this extension on Mozilla Addons. ありがとうございます！
