I stumbled on this link here, where you can get a demo of Taiko no Tatsujin for mobile phones <: It only has 10 songs, but I don't know which because I dont have japanese fonts installed on my phone, so I only see squares lol. It's java and made for QVGA (320*240) phones [: The ghosting is also worse than Taiko DS lol but its still fun (and free lol)
Get here:
