ATM Machines in Japan

What is important to remember is that Japan is still very much a cash country. Many places like small shops and restaurants as well as ryokans in the countryside will only take cash. Therefor it is very important in this safe country to carry more cash then you might be used to. Not all ATM that you see serves you using an international card. The best place to go is to the post office during office hours and the 7 Eleven stores that are open around the clock. There is no problem to get change on large bills at any place!
