Japanese input is doable without any system changes. Mostly adding language as well. Some software does need you to add language packs to system directories - that’s one example where an overlay fs is useful.
Mostly it’s good when you need to add specific packages (I ran into xmodmap not being available for instance). Or if you need something such as a custom keyboard layout (technically possible in your home though).
