• SIM card and Mobile Wi-Fi Rental for Visitors to Japan

Japan is seeing an increase in foreign tourists. More and more of those foreigners each year bring their smartphones or tablets, and the most common complaint by those travelers is the difficulty of getting access to the Internet due to the lack of free public Wi-Fi spots in Japan. Unfortunately, it is true; the Wi-Fi situation for foreign travelers in Japan is not good.

Some enterprises have started installing Free-Wi-Fi spots in towns to help improve the situation, but because Wi-Fi does not reach far, and in many cases it requires registration or a special app, or limits the usage to 15 to 30 minute, these Wi-Fi spots are not very convenient. Although hotels and ryokans are making progress in Wi-Fi availability, you would still need to look for a way to get online once you’re out in the cities. If you want to use Google Map on your way to your destination or post updates on Facebook or Twitter whenever and wherever, it’s the best for you to get your own SIM card or Mobile Wi-Fi.
