WARNING IF YOU PLAN TO SET YOUR FIRE TV STICK TO ENGLISH! I have a prime account on amazon.co.jp and cannot log in to Amazon Japan Prime Video unless the Fire TV stick is in Japanese language mode. There is no way to select the country of Japan and English language combination (surprising since the amazon.co.jp website allows it). You must select the country and language when you first set up the Fire TV stick, and you have to restore it to the factory default (which takes forever) if you want to change the country or language. This is unfortunate for the members of my family who do not read Japanese. I spent the past hour chatting with a customer service representative and the final conclusion was *no way around it*.
