Japan uses three different mobile systems actually.

There's PDC which is a digital standard that uses a TDMA air interface (like GSM, but in a different way). There's a Japan-only CDMA system and there's 3-G WCDMA.

I think an European, Asian or South American GSM phone could only roam in the 3G networks (Vodaphone J-Phone in particular) but you'd need a 3G handset for that.


Hope this helps,
