Hey that's the first Inuyasha theme song Change The World. Have you not actually heard it. I'm sure you could find it online somewhere as audio if you wanted it. But anyway, all the consonants are as you would expect and the vowels are as follows:
a - ah
i - ee
u - oo
e - eh
o - oh
That's good for a start and if you want to learn more, do a quick google on "online japanese lessons" or something and I'm sure you'll find more than enough beginner tutorials and things.
