I'm probably misreading you a little bit, but here's my two yen.
There were a bunch of silly operating systems in the history of computing, and Japan had a few too. TRON was pointed out in another thread, which still exists in some embedded stuff, even in modern stuff you may have used before, for example the Nintendo Switch joy-cons.
But TBH, there can only be a handful of operating systems that actually matter. So you'd have to outpush some extremely pushy companies in a very tight space, and the market for commercial operating systems is almost dead anyway.
