In Japan people tend to use cash for most transactions. So at some point you will likely need to withdraw money. Most ATMs in Japan only allow you to withdraw cash if the card you are using was issued in Japan. Exceptions are postal ATMs, found mainly at post offices, and Seven Bank ATMs, at some 20,000 7-Eleven convenience stores. Seven Bank ATMs are available 24 hours a day, all year.

3.WI-FI

Having Wi-Fi in Japan is pretty useful. Japan Wireless is a company that provides rental pocket wi-fi devices that deliver high-speed internet at affordable rates. Book before you leave for Japan, as they send the pocket device to you before your trip. You pay to use it for as long as you like, and then just send it back in the provided return envelope after your stay!

Car Rental Information
To rent a car for your trip in Japan you will need to make sure you have a valid license. An International Driving Permit issued based on the Geneva Convention is a valid license that you can get issued at home before your trip. A license issued by Switzerland, Germany, France, Belgium, Monaco, Estonia, or Taiwan is valid in Japan, but you will need an official Japanese translation. It is essential you carry this with your original license.
