On the link BlackBerry - BlackBerry 8830 , if you check out the specification (at the bottom) it says that the network it supports is Dual-band 800/1900 Mhz CDMA2000 1X Ev-DO networks

I then found link from QUALCOMM ( QUALCOMM Press Center - QUALCOMM Congratulates KDDI on Commercial Launch of CDMA2000 1xEV-DO Services in Major Japanese Cities ) which mentions that KDDI telecomms has launched CDMA2000 1X Ev-DO service.

This would imply that if someone went to Japan, a manual network scan would pick up this carrier and if selected, would allow them to hook onto this network and use it successfully.
KDDI has EV-DO service in the 1700 or 1800 MHz band (i can't remember which, I just know it is the same as KTF in South Korea). VZW uses 850 and 1900 MHz. Thus, VZW can't roam on KDDI.

Addtionally, if roaming service was available in Japan with a CDMA phone, then VZW's site would list it as a coverage area, which it does not.
