Japanese IME

If you need to enter some text in Japanese, the Japanese Input Method Editor (IME) for Windows lets you enter text using hiragana or katakana characters while using a typical keyboard with 101-105 keys. The IME also converts your input into kanji characters. Using the IME doesn't require changing your current Windows display language.

Add support for Japanese input

To add support for Japanese input to Windows:

  1. Open Settings and select Time & language > Language & region.
  2. Select Add a language. Select Japanese from the list and select Next.
  3. Consider if you need any of the Optional language features. If you want to enter Japanese text while keeping your current Windows display language, none of them are necessary. When you're happy with your choices, select Install.

Type Japanese text

The Windows system tray shows which keyboard layout is currently active, for example, ENG. You can switch between installed layouts (layouts in the Preferred languages list in Settings) by selecting the Windows logo key + Spacebar.

If you prefer, you can also change the layout by selecting the system tray icon and selecting the layout from the list. This method can be faster if you have more than two languages installed.

Windows 11 with several keyboard layouts installed.

If multiple IME/keyboards are installed for a given language, the list and the tray icon will show a combination of language and layout.

To type text using Japanese characters:

  1. Select Japanese Microsoft IME. The system tray now shows a icon instead of ENG, and a new icon showing A (indicating English input mode, also known as half-width alphanumeric) appears next to it.
  2. Select the A icon. The input mode changes to indicating that you can now type Japanese hiragana characters. You can also change between Japanese and English input by selecting the Alt key + Back quote (`).
  3. Start typing the Japanese character or word using its phonetic transcription. The conversion candidate window opens and shows matches for what you typed. You can keep typing and the candidate window updates in real time. Select the Spacebar to convert your current input into kanji.
  4. To move the focus to the candidate window, select the Tab key. To navigate the window, use your mouse or the following keys:
    • Down and Up arrow keys to move to the next/previous candidate
    • Tab key to expand the list to a table that you can navigate with the arrow
    • Number keys to quickly select the corresponding candidate
    • Enter to select the currently focused candidate
    • Esc to close the window without making a selection

  • Input settings such as punctuation
  • Character type and set conversion candidate settings
  • Predictive input settings
  • Keyboard and touch-related settings
  • IME learning and dictionary settings
  • IME appearance settings
  • Usage data collection settings

For more information about these settings, see Microsoft Japanese IME.

Change character width and input mode

The Japanese IME allows typing with both half-width and full-width characters. To change the width and input mode, open the right-click menu and select from the following options:

  • Hiragana
  • Full-width Katakana
  • Full-width Alphanumeric
  • Half-width Katakana
  • Half-width Alphanumeric

Use the IME Pad for advanced writing options

To open the IME Pad, open the right-click menu and select IME Pad. It has three modes that you can select with the icons on the left side of the window:

  • Hand Writing (JA): You can draw a Japanese character in the left box and then select one of the recognized characters from the right box to insert it into your text.
  • Character List (JA): You can select any font installed on the computer, view every character available with that font, and select them for insertion into your text.
  • Soft Keyboard (JA): You can enter alphanumeric characters, hiragana, and katakana with an on-screen keyboard that resembles the Windows On-Screen Keyboard (OSK).
  • Strokes (CH): You can select any available character to insert it into your text. You can sort the character list by the number of strokes used to write it.
  • Radical (CH): Works like the Strokes mode, but you first choose the radical (a part of the final character) based on the number of strokes used to write it, and then choose a character or syllable that includes the selected radical.

Finally, the IME Pad lets you use the Backspace, Delete, Enter, Esc, Spacebar, Convert, and arrow keys with your mouse or touchpad.

Use the IME toolbar to access options

To open the IME toolbar, open the right-click menu and select IME toolbar. It gives you another way to access some of the options discussed in this article.

  • You can change character width and input mode.
  • You can open the IME Pad.
  • You can open the user dictionary or add-on dictionary.
  • You can switch between kana and romaji input.
  • You can open the Microsoft Japanese IME settings page.

Example

The Japanese word for spring is 春, which is a single kanji character. "Haru" is its phonetic romanization.

To type the word, select the Japanese keyboard layout from the system tray and change to Japanese hiragana input mode, if necessary. Then type "haru" without any spaces. You see that the Japanese IME turns your input into hiragana syllables: はる

The candidate window also opens and shows a list of matches. But all you need to finish the character and convert it into kanji is to select the Spacebar once. If you select Enter, the Japanese IME keeps the word in hiragana.
