 This is no longer required on Android 7.0+. Instead add Japanese to your language list in Settings > Languages & input > Languages to show the correct Kanji across all apps.
Android renders Chinese glyphs by default when the system language is set to anything but Japanese. Kanji Fix changes the order of system fonts in Android 4.1 and up to prioritize Japanese Kanji over the Chinese equivalent.
This should be a last resort method to making Japanese Kanji show in apps instead of the Chinese default.
1. This app changes system files. As a result, 
 You will need to revert before applying an OTA update.
2. This can make other unicode languages look awful, including Russian.
3. 4.4+ fixed Japanese font rendering in WebViews (Chrome, Wanikani Mobile, and other apps), although this is still required for apps using native fonts with native TextViews.
Make a backup if concerned about data loss. A restart is required after applying to see the updated glyphs.
See the screenshot above for a comparison of the different fonts. An alternative font, IPAGothic, is provided for a less "rounded" font, and can be installed by selecting "Install Alternative Font" from the menu.
