As far as I know, there isn't a limit of power / speed for kei car category. In the old days Suzuki made a kei car that was "too powerful", the government "communicated" with them, and they settled with 64hps. Since then all the manufactures self-imposed the 64hps limit, but it's still legal for someone to power up their own car.

Smart K is another non-Japanese kei car that's more powerful.

That's pretty funny. Japanese manufacturers also had an informal agreement to limit motorcycles to 310kmh for a while: https://medium.com/gasolirium/the-gentlemens-agreement-abc60...
