What's the correct model to get for use in Japan (and how!)?

Still love my Z3 but MM OTA update fried the wifi&bt within a week. (Bad Sony. Bad.) So OP3 I'm ready for you.

I'm going to order a USA version and have my friend ship it to tokyo.

• question1- Is there a better way to get one? After all, it's originating in China...
• question2- Is USA version the way to go? The only info I have to rely on is the result from http://ift.tt/1AsH6X0 :

OnePlus 3 North America Model + Japan + Japan Travel SIM (data only) 2G Network: Carrier Network does not support 2G 3G Network: 2100MHz 4G LTE Network: Band1-2100MHz

my Z3 D6653 works fine here in tokyo and is described as:
