China and Japan switched from their old calendar system, which was using the start of their current emperor inauguration as the first year, reset with each new emperor.
So I guess it was easier to choose the only correct date format.
That just dictates what number the year starts at, not the order of writing down a date.
They do traditionally go from general to specific though. When writing an address in China, you go Country - State - City - Street - Person (I forget where the postal code goes).
