She said during her Hawaii interview that she would sing songs that her fans would want to hear and not just the ones on TITO to promote the album.

It's in 5 parts and I don't remember which part she says it but she does.
So rest assured she will sing plenty of Japanese songs.

Also why are the setlists so small? she's gonna sing at least 15 songs, this is a concert after all.
I wouldn't be surprised if she rearranged many of her songs also.

Here is the real setlist: (well not really)

1. On and On
2. Take Five
3 Beautiful World
4. Kremlin Dusk
5. Hotel Lobby
6. Dirty Desire
7. Come back to me
8. Sakura Drops
9. Keep Tryin'
10. Traveling
11. Simple and Clean
12. Automatic
13. Prisoner of Love
14. MCML FYI
15. This One
16. Colors
17. Flavor of Life
18. Addicted to you
19. Tokyo Nights
20. Blue
21. Me Meuro
