I donโt actually read much on the tablet, I mostly use it as a look up device. xD As to your problem, you need a Japanese address to buy the books. This post explains how to get it to work: Access to Japanese kindle books on amazon - #3 by slerched
I decided to not even rewatch the latest trailer, to be as spoiler free as possible but still getting to watch the trailer. I saw some glimpses that have me excited and Iโd rather wait to see if they turn out to be true. 
I think this comes from trying to replay Breath of the Wild earlier this year but realizing I wasnโt having much fun, because the mystery/wonder was gone because Iโd already found most everything (I didnโt 100% because there are too many korok seeds, but otherwise did pretty much everything else). So I want to preserve as much of that for the game while also getting in some of the hype!!!
