The Xperia Z3 (401SO) for SoftBank has today launched in Japan in all four colours (black, white, copper and silver green). NTT DoCoMo and au by KDDI are already offering the Xperia Z3, but the SoftBank version is closest to the global model in terms of branding (you won’t notice any SoftBank logos on this Xperia Z3). Like the other Japanese models, it does carry 32GB of internal storage though (versus 16GB for global models). The list price is 69,120 Yen (£374, €468, $587) and is available via SoftBank right now.
