Attending Wrestle Kingdom/Japan for the first time

Hi all, I'm going to be attending Wrestle Kingdom for the first time (and going to Japan for the first time) alone this year.

I was just wondering if anyone has an advice on navigating Japan as a westerner for the first time? E.g. places to eat, how to use the public transport or navigate Japan as an English speaker, using cash/card for transactions, or even places to explore as a huge wrestling fan etc. Any advice or recommendations would be greatly appreciated, thank you!
