Yeah, that's the other problem... Kei cars/trucks, despite being 25 years old, have been banned in a few states because "safety" (even though you can buy a new motorcycle, or a US-spec 1950 whatever, etc).

You're probably, maybe ok for something like a 25 year old full-size car that doesn't look too wild (ie, could pass a a US-spec). Like a Japanese-market Lancer Evo, or Mitsubishi Pajero.
