I might be going to Korea and/or Japan. Is there a huge language barrier? I'm the kind of dude who can generally find his way around without a lot of help. But I've only travelled mostly to tourist friendly /English speaking countries (and Europe), and the Caribbean.
I'm not afraid or anything,I'm willing to step out on the ledge if need be; I'm just wondering if it'll be easy to navigate as an English speaking person (street signs, merchants, etc). Any tips or info?
