@TerminalAutism @PhenomX6 Key differences between Japanese QWERTY and American QWERTY are in the special characters, and the fact that Japanese ones have more keys.
Shift + 0 in principle isn't ASSigned to anything, so it uses a tilde (~) as a placeholder, though sometimes it seems to use a backslash (\) or a pipe (|) (no dirty thoughts intended) on other OS's.

The space key is smaller to make room for the 無交換, 交換, and カタカナ/ひらがな/ローマ字 keys.
On American ones there are 2 keys between the 0 and backspace, on Japanese there are 3 keys.
On American ones there's 3 keys between M and right shift, on Japanese there are 4 keys.
On American ones there's 2 keys between L and enter, on Japanese ones there are 3 keys.

And the only reason I know that is because I recently worked for a customer at their own office, and they all use some IdeaPad laptops that have keyboards where Japan-only keys have no gap between them and international ones.

Exactly like this:
