Miata, BRZ, Nissan Z, and GT-R? Toyota's GR86 is BRZ derived but still counts, though their Supra is a BMW. Honda's closest thing is the Civic Type R, but they're bringing back the Prelude soon. Mitsubishi are the odd one out, all they have is an SUV recycling the Eclipse's name.
There's no million dollar Japanese supercars competing against Lamborghinis and McLarens, but I wouldn't say they stopped making sports cars.
