Heading to the land of the rising sun? You might think that travelling to such a technologically advanced country would mean you have no problems getting connected. But Japan can present some difficulties for short term visitors, keep reading to find the best SIM card for Japan.

By law, visitors on a tourist visa are not allowed to buy voice SIM cards, so your only option is to buy a prepaid data only SIM, and then use VOIP apps if you need to make calls. On this page I look at the options for buying different tourist data only sims and then look at another option of renting a voice SIM.

Some airports have vending machines, and some have 7-11 stores where you can purchase SIMs. You can also head to an electronic store. Yodobashi Camera and BIC Camera stores will stock these SIM cards and can be found in the centre of all major towns and cities. These SIMs are not triple cut and the Nano, Micro and full size SIMs come in different packaging; so make sure you pick the right one.

Alternatively, you can order a SIM online, and have it delivered either internationally to your home, or to your hotel to pick-up on arrival.

Japan has three major phone networks, and has no GSM network but widespread 3G and 4G/LTE. So if your device is not 3G/4G, then it will not work.

Phone / Wireless Hotspot Mifi rental

If you really need to make phone calls, and can’t use VOIP services like Skype; then renting a phone is another option.To get around the SIM laws, companies offer rental of phones and wifi hotspots. These can be sent to your hotel, or picked up from electronics stores and at the airport. Try: https://www.rentafonejapan.com/

If your phone is locked and you cannot fit a data SIM card, you can also rent a wifi hotspot from this company. Alternatively you could place your data SIM in your own mifi. 


 Wifi Availability

There is a growing number of free Wifi hotspots, in shops, stations, hotels and trains etc.
