Hey tony, i dunno if you found your info but I too have searched for these girls, here is the info you are looking for, and also supplimental info that will help clarify some things
The girls from the commercial are part of "Taiko Project", you can find them at this link: http://www.taikoproject.com/00/content/00.html
you can also check out: http://www.pbase.com/bryanyamami/root and check the "vegas tour" for the mitsubishi commercial
the girls are just part of the full band (no doubt they used only the girls for their obvious sex appeal)
Taiko Project is far more youth oriented, more like a "stomp" version of kodo. Kodo is a seperate group that is closer to "traditional" styles. Most kodo members are also older and primarily male dominated (i dont know if any females play drums in kodo, i had the opportunity to go to a kodo concert recently, however it was not the full group that played).
Well I hope this helped.
> Can anyone tell me if the Asian girls dressed in red, pounding the drums in the Mitsubishi commercial are a real act? If so, what is their name?
