Japanese (Kotoeri) input method disappears on Mac OS X

This morning I found I could no longer switch to the Japanese keyboard layout on my mac – only the US layout was listed. So I went to System Preferences > International > Input menu and looked for the Japanese Input Method (called Kotoeri on the mac). There was no sign of it; here’s how it got fixed in the end.

Check that it’s a preferences / configuration problem:

  • Create a new user (System Preferences > Accounts)
  • Log out and log in as new user
  • If the input methods are displayed correctly for this other user (see below), it must be a settings issue.

International (System Preferences)

Fix the preferences problem:

  • Log back in as the main user
  • Drag these two files from /Users/MAINUSERNAME/Library/Preferences to the Desktop:
  • com.apple.menuextra.textinput.plist
    com.apple.system.preferences.plist

  • Restart, and presto, Japanese is back on the menu – いただきます!

Note: This is probably relevant for these other Input Methods also, as they disappeared and reappeared along with Japanese (kotoeri):

  • Hangul
  • Simplified Chinese
  • Tamil Input Method
  • Traditional Chinese
  • Vietnamese UniKey
