The US as I still wish to meet up with my internet friends someday, especially the ones I've known for about 5 years by now and still talk to, so Jan for example! It'd be great to finally see them in person honestly, they're amazing friends and I treasure them a lot.
Second would be Japan as I'd love to see the landscape and culture for myself. I genuinely am interested in traveling around the country for sightseeing, but of course visiting Tokyo as well and see how it is there.
Third would be Italy as I've always wanted to travel there in general, just that my parents don't like going to warmer countries, which is kind of a shame really; I really want to go to Rome someday. Also, Pizza.
Fourth may actually be France as well, even though I've already been to the place before, and it'd be Paris again too; I just want to be able to go there without actually being pressurized by people to go to certain places as I was last time I was there, so I can enjoy the city on my own.
And fifth would be the UK! Even though I've been there countless times, I still want to go back. I'd rather visit London for once though, as I've mostly been near the countryside. Not that I didn't like it there though as I've been in a few really nice countryside towns, and actually really like the landscapes in the UK, but I just want to have a few days in the city as well and see what's there as well.
