Japan

lpg strong pound.

you got somewhere you can stay (i dont mean hotels!). If you can get free accomodation (from a friend or an ex-girlfriend), it'd be sweet. tokyo is quite expensive (i've heard).

Japan's a cheap place to visit these days. Business hotels can be had for GBP 25-30 a night, depending on the location, with breakfast and internet access thrown in. It's easy to get a big meal for about five quid, too. I speak Japanese, though: it might be a bit harder to find the bargains without understanding the language.
