Japanese software don't get much recognition. Nintendo Switch(1 and 2) isn't running Linux, and it supports NVIDIA graphics stack. That shouldn't be possible unless Nintendo is actually capable of building a graphical operating system, which it is. Hardly anyone realizes this. There are also tons of (trashy)software embedded in Japanese hardware and none of those somehow mentally register.

Japan is also extremely weary of getting in the way of US. Software is one of few remaining consumer high tech domains that US leads. Challenging that without a good reason isn't a great idea.
