Im exactly 15 but Im planning on going to japan as a Summer Vacation with a very good friend of mine thats 21.I already thought of the places I would book hotels with my friend at and that places I would visit. But the process of getting a passport,visitor visa and such and what I would need...kinda troubles me at that point...I can financially support myself alone but you need to be of a certain age i believe to book hotels so thats reason for my friend...anyhow I just need to know how to get a passport:I checked around on google but I want to hear a more clearer explanation by you guys same goes for tourist visa which allows for what was it 90 days I think o.o.So yea basically im asking mind giving me a detailed and good explanation for how to get passport,visitor visa and such so I can be better prepared for this summer unless something pops up and Im pushed away for having a vacation there.
