I'm not sure if anyone will be able to answer this, but who knows. I'm moving from Japan to the UK next week and I have to buy new phones for myself any my wife. The Nexus 4 looks like a really good option, but my wife needs the UI to be in the Japanese locale. I know I can set a custom locale so that her apps are Japanese, but she wants the settings on the phone, etc, in Japanese. I suspect that phones off the shelf won't have a Japanese locale compiled in. When you order a phone from Play, what locales are compiled in? I know there's a Japanese version of the Nexus 7, but when you go through the order form it seems to give you options only for the location you are in. So, for instance, the descriptions for the Nexus 7 were all in Japanese, even though my locale on my browser is English -- so they must be keying on my IP address. There seemed to be no option for ordering a device with specific localization.
I'm wondering if I will be better to find a phone that will run Cyanogen mod and compile in the Japanese locale myself... Or I can tell my wife that running her phone in English is good practice
(She's always telling me to run my computer in Japanese...)
