Setting up your PC to read and write in Japanese is free, easy and just takes a few minutes. Doing a search on “Japanese Input” will give you many results to choose from, many of which reiterate or direct you to a Microsoft download page where you find instructions on how to install an Input Method Editor (IME)
Once you have installed the Japanese IME, there will be a language drop-down list on your toolbar where you can select from amongst the languages you have installed. Choose JP for Japanese, and begin typing in romaji.
As you type in romaji, the syllables come up in hiragana ひらがな which you can choose to convert into or kanji 漢字 by selecting from a drop-down list. You can also select for katakana カタカナ.
Once you’ve done all that, write to me 下さい !
