To give a little back story as to why I am even planning on such a vacation is it has always been my boyfriend's dream to travel to Japan (specifically Tokyo) and it has been mine too. Our anniversary is on Oct. 23rd so I was hoping to either maybe have a plan on where we will be visiting/staying or have the tickets purchased for either a future day or for around that time. 

Interests he had: 
-This is this huge mega arcade there somewhere but I have no idea what it is called or where it even is. 
-He wants to visit the "Pokemon Center" for sure but again I don't know where it is located or even if that's what it is called. 

I myself wanted to visit some onsens (mixed bath would be preferred) and wanted to know if you guys recommended any.

I want to stay for about 2 weeks example: Oct. 20th-Nov. 2nd

Any good hotel suggestions that are close by some awesome food places/entertainment/place of interest? 

Also throw some other suggestions at me, it would be greatly appreciated!

Some other questions I had as well:
Is Japan English-only speaker friendly? Because I only know simple sayings in Japanese i.e., How are you?, Where is the bathroom?, etc.
Do they accept Debit cards? (of course I should always bring a bit of cash on me but I always get nervous carrying around cash and also will their ATMs have an English option?)
Is there anything I should be aware of when visiting? For example, should I be cautious of pick pocketers or something like that? I'm rather paranoid and being out of the country definitely wont help with that. 

So obligatory
