Contract only as usual. As a person living in Japan, I'm always pissed off by how smartphones are always sold through carriers and must go with contract. I can't just go to a shop and buy an unlocked smartphone. Heck, I can't find the latest Sony phones in its home country (which are already sold in other Asian countries). iPhone 6 is an exception, which can be bought unlocked at stores. I wish the other major manufacturers would do this and end Japanese carriers' hegemony.
