Japanese pronunciation is one of the easiest out of all the Asian languages. It is based on just five simple vowel sounds. Once you master those vowel sounds they rest of the sounds are easy as cake. Even if you pronounce your Japanese with a heavy foreign accent over time you can correct your accent so don't get depressed if your Alabama accent seems to be holding you back!
