Not a very difficult song to play at all, and it sounds really nice. Listen 
to the recording for the rhythm.

Verse:

G (320003@1)A (x02220@1)Bm (x24432@1)BmG  A (x02220@1)Bm (x24432@1)B*
Em  F#  Bm Am
Em  F#  Bm Am

G (320003@1)A (x02220@1)Bm (x24432@1)BmG  A (x02220@1)Bm (x24432@1)BEm (x2444x@1) F#  Bm Am
Em  F#  Bm-Bbm-Am D

* I noticed a lot of people playing Bm instead of B. It sounds fine but 
Shiina Ringo definitely played B and imo it sounds much nicer.

Chorus:

G (320003@1)A (x02220@1)BmG (x24432@1) A  Bm-Bbm-Am D

Instrumental:

Repeat G  A  Bm
