What would you want to do if you went to Japan?

I don't know much about Japan tbh except I find their participation in World War II interesting. I'd have to read on their history before I went there otherwise I'd feel like a tourist rather than a researcher.

I am not for sure, I am going this summer on the 29th of May so I will try many different things.

I'd try the crazy restaurants. I've heard of a place that makes everything out of mayonnaise, even the vanilla smoothie has mayonnaise. and I'd try the meat flavored ice creams they have in japan.

First thing id do,its go eat all kind of goodies for a day,than go for the second day in Akiba for all the animes and stuff,and head to a city which have all the good Rotenburo to go relax,with eyes burning from un-censored public

I'll buy second-hand books, meet up with my a few Japanese friends as well as an acquaintance from college who is currently studying computer science in the University of Tokyo(let him show me around the campus!!),shop for skincare products,visit Comic Market(if possible)...
