Will a UK iPhone 5 work in Japan?

It's on pay as you go here in the UK, and I intend to switch it to a pay as you go nano-SIM in Japan. I'm just wondering will this be possible? I want it to be able to work in Japan, obviously… Thanks!

  • Will my vodafone iphone5 work in Japan? Last year in Japan my iPhone 4 was pretty much just an iPod for the whole trip. I've got an iPhone 5 now but if it's not going to work then I probably won't bother taking it Is there any kind of pay as you go SIM card I can buy to use in my phone while I'm there?
  • Will my iPhone work in US while here from Okinawa, Japan? I'm in the US for several weeks. My iPhone is not working. I have it subscribed to service in Okinawa Japan. Should my iPhone be working properly to make calls and send MMS, and check email? Is there something I need to do to make it work? Thank you. Thank you Tech One. But do I have to change carriers while I'm here? I'm still active with my current carrier from Japan.
  • Will a Verizon iPhone work in Japan? I might go to the World Scout Jamboree in Japan in 2015, by then I will have the model of iPhone that comes out in fall 2014, but would a Verizon iPhone work there?
  • Will a straight talk iPhone work in Japan with a Japanese sim card? I'm pretty sure you can put a sim card in it but I was curious I want to go to Japan sometime but it is difficult getting a phone there being a foreigner and it is pretty expensive but I see people switch their sim cards with there phones a lot like with at&t ect. I wonder if that would work the same overseas? Like putting a japanese cell service provider's sim card in the phone? This probably sounds really stupid though but thank you!
