Budget

Hey! First time traveler here, was wondering how much budget i'd need for a good 2 week trip to japan.

I'd preferably check out a couple other cities but mainly wanna stay in tokyo, buy some cool clothes, souvenirs, do some fun activities and maybe go out clubbing a night or two.

How much do you guys think i need? I was thinking 1500 to 2000 usd.

Thanks in advance!
