Windows 10 setup
This is a walkthrough of the UI using a corporate installation of Windows 10. It is possible that this might differ for someone using a consumer version -- on Windows XP, for instance, the language resources were not included in the default install, and required a separate installation disk or downloading first.
- Click Start and type Language. Select Language Settings.
- Under Preferred languages, click Add a language.
- For Choose a language to install, type japanese to shorten the list, select Japanese, and click Next.
- For Install language features, the Preferred language will show only 日本語, so leave that as-is. Make sure to U̲N̲C̲H̲E̲C̲K̲ the boxes for Install language pack (this installs all the language resources to display Japanese UI, which uses up a chunk of drive space and which you don't need), and for Set as my Windows display language (since you want to keep English for your UI display). Then click Install.
- You should be back at the Language settings dialog. Make sure that the Windows display language is still set to your preferred flavor of English. Also make sure that Japanese is shown in the list under Preferred languages, and that Japanese appears u̲n̲d̲e̲r̲ your preferred variety of English.
- The input language defaults to ENG. Now click Keyboard to change this to the Japanese IME.
- Under Override for default input method, open the drop-down and select Japanese - Microsoft IME.
- Under Switching input methods, you should probably leave these unchecked, unless you have other IMEs installed (perhaps different Japanese IMEs, or even IMEs for other languages like Korean or Chinese).
- Optionally, click the blue Language bar options or Input language hot keys to configure those options as well.
- Check the systray. You should see the Japanese IME icons just to the left of the clock.
The A shows that the IME is in "Alphabet" mode. The square with the circle and the J inside it shows that the Windows keyboard language is set to "Japanese".
You should be done. As with anything Windows, you might need to reboot to make sure that the new settings stick.
When in a text field, use either of these key combinations to toggle between "Alphabet" mode (for English) and "Romaji Input + Conversion" mode (for Japanese):
- Left ALT + ` (backtick, the key on the upper left below Esc)
- Left SHIFT + CAPSLOCK
