I respect rance's advice but I disagree with this. tokyo is probably the cheapest developed city in the world. whatever your budget is in your own country, I would say cut it by 30% or more. not even clubs are really that expensive. obviously once you start factoring in a lifestyle where you are buying arbitrarily expensive drinks for other women, the sky is the limit in terms of how much money you can waste. outside of apartment costs, like, a thousand dollars, really, all spending is discretionary as far as I see it. if you plan on targeting high maintenance women, yeah, that can get expensive. but thats more dependant on the woman herself than thecity.
