Here's my deal. I'm planning a trip to Japan for just a few days. I'm not looking to set up a whole extravagant vacation or anything. Quite the oposite actually. My plan is that I really have no real plan. I was just going to pack a back pack with a couple changes of cloths, some essentials, and bring about $1000 in cash. Basically just fly in and go from there. Sort of an adventure. I'd basically just be on foot seeing the sights and whatnot. Some obsticles that I face is that I speak little to no Japanese. I could probably brush up on it a bit before I leave but I would have very limited knowledge of the language.
Do you think this is a good idea, or am I setting myself up for a very bad situation? What are some obstacles I could encounter?
