I still don't understand why people are so obsessed with Japan. Its the country of anime. Oh crap I think I answered my own question.
When I go overseas I'm going to Stockholm, Moscow, Warsaw, Budapest and maybe Istanbul. Personally I'd avoid going to Japan full stop now (Used to love Japan but not now) but everyone likes different places mine just happens to be Europe
Good luck on your trip though.
PS: You've given me motivation to start saving money faster for my trip xD.
