Before I dive in and tell you about all the places that I visited throughout Japan, there are a few things you need to know/prepare for if you want to travel there. I’ll briefly go through them:
You’ll need a Visa, MasterCard or equivalent credit card to use throughout Japan. K-Net ATM cards will only work in limited locations such as post offices. After purchasing flight tickets and reserving accommodation, your primary expenses will revolve around food, transportation, tours/resorts (if any) and any other services or purchases made there. It is true that Japan is an expensive country to live in, but if you plan your trip and make reasonable estimations, you should be on the safe side of things.
Just to give you a rough idea: a small bottle of Cola —they’re made out of plastic, they don’t have them in cans— from a vending machine in Tokyo costs ¥120 or 350 fils.
Carry Your Passport with You
Don’t leave your passport in the hotel safety box; it is the only proof of identification that foreigners of Japan have. You are expected to present it to police officers or government officials on demand.
