While free WiFi access can be difficult to find when travelling in Japan, an easy solution is to rent a pocket WiFi device throughout your stay. Haruzou from Deep Japan writes about a service called PuPuRu International, which will deliver you a pocket WiFi device to the airport or your hotel. The rental for this device is very cost effective with the added bonus of an English support line. You need to ensure you order the device three days before you need it and then when you are finished with it, simply place it in an envelope provided and drop it in a post box. So for around ¥400 a day, you can have access to the internet whenever and wherever you like while travelling in Japan.
