How do I import a car to Japan?

Hi, So I need to know how hard it is to bring a foreign car in. I am from Australia, where we have all kinds of preposterous laws to stop people importing vehicles...it seems easier in Japan? Aside from the normal taxes that ppl pay (aquisition tax, annual tax) and the parking space requirement, is there any other obstacle other than the shipping fees and emissions test? Any other hidden regulations about what can/can't be imported? Thanks!!
