Thread: any song with just guitar or piano?

Hi everybody!
I was just wondering if any of you know a nice anime song ( or non anime), of course in Japanese, which the voice is mainly accompanied by a accoustic guitar or a keyboard. (Preferably, not very complicated, as my partner who plays instruments has just a pair of weeks to prepare)

thanks a lot!

Try miyavi.
not sure about complicated though...depends what you would call complicated.

Piano? Keyboard? Classical?
Joe Hisaishi, very good and beautiful music.
Mononoke hime, Spirited Away etc.
