The J icon means Japanese text entry is active.

The (hiragana "a") icon means you are typing in hiragana mode. In this mode, you type romaji (alphabetic) characters, and the computer converts these characters to hiragana automatically.

Click , and the icon will change to . In this mode (called alphanumeric mode), the computer does not convert what you type to hiragana.

To access more options, right-click the or icon.

  • Two katakana modes convert what you type into katakana. One mode is full-width katakana (全角 zenkaku); the other is half-width katakana (半角 hankaku). In almost all cases, full-width is the best choice.
  • Likewise, you can enter full-width or half-width alphanumeric characters. Generally, when writing horizontally, half-width alphanumerics are preferred. When writing Japanese vertically, full-width alphanumerics are common.

You're all done!
You can now type Japanese text in most applications. To switch to Japanese text entry, follow these steps:
  1. Open an application where you can type in text, such as Word.
  2. Open the language menu as described above, and choose Japanese.
  3. Make sure (hiragana mode) is displayed in the status bar. (If appears, click it to switch to hiragana mode, or right-click and choose Hiragana.)
  4. Type romaji (such as "nihongo"). As you type, your romaji will be converted to hiragana automatically. The hiragana characters will be underlined with a dashed line. That is your indication that these characters can be converted to Kanji (see below).
    Hit the spacebar, and you'll see the system's recommended Kanji conversion (or the conversion might be plain hiragana—it depends on what you type).
    Hit the spacebar again, and you'll see all the possible Kanji conversions. Use the up and down cursor keys to choose the one that fits what you're typing, and hit Enter. Your text will be updated automatically.
