japans answer to american muscle, where as the american cars were mainly from the 60's/70's, japanese were from the late 80's to Todayish. Where as American muscle relied on mostly beefy V8's with TONS of torque, Japanese usually range from I4's to V6's fitted with twin turbos. In my personal belief, both are good, it just depends on your tastes.
