I'm planning on one day visiting Tokyo and maybe try and live there. but I'm not sure if it will work out, I'm 21 and a Portuguese soldier and thinking about entering police academy. I'm worried about work issues, the only thing I'm really good at is computers and the whole "soldier lifestyle" I'm pretty sure i can't join Japanese police force right? anything i could do out there that you guys recommend? and how could i get papers to stay and live in japan? also how does the currency work out there? from euro to yen?
