Actually the opposite, NSX is super exotic in Japan. There are less sold there, 7394 to be exact. The low production # is just one of many....reasons why NSX is in fact an exotic car.In Japan, the NSX is probably far from what one would call exotic, but maybe here in the States it is. It's the same with a Corvette. While a Corvette isn't anything special in the States, it is special overseas.
NSX is far more respected in Japan than in US. Many publications even go as far as calling NSX the national treasure of Japan.
I travel to Japan average 6 times a year since 1998. My passport have all my traveling records. NSX sightings are always extremely rare for me compare to Ferraries, GTRs, etc. Look up at Carsensor.net (largest used car site in Japan similar to Autotrader to USA). There are very few NSXes available, and the used car price is stronger and higher in Japan compare to USA.
While a fantastic car, Corvette is not very special in overseas. The # sold oversea are very low for the population in other countries. Look at NSX, Porsches, Ferraries, BMWs, Mercedes, other Japanese cars. These cars all sell very well outside of their home countries.
As for my personal opinion, yes, NSX is an exotic car. Still the best looking car came out of Japan. Sometimes when I see one, I still drop my jaw, especially when I get carry away and forget that I also own one. Everytime I drive it, I still can't believe how well the car is built, how amazingly fun it is to drive.
