Telecommunication in Japan
Cellular communication in Japan really does not work on GSM. To guarantee higher speeds of data transmission, other frequencies are used – PDC and WCDM. Many other countries are planning to switch to these frequencies as well, but so far Japan is ahead of everyone and everything.
It will be difficult to find SIM card and internet provider if you have an old phone model. SIM cards in Japan are designed for phones released after 2008. As a result, you can only connect to a Wi-Fi network and make calls over the Internet.
Mobile Operators in Japan
If you have a brand new smartphone and want to buy local Japanese SIM card, then choose one of the three major operators:
- NTT DoCoMo;
- KDDI;
- SoftBank.
All of them work with 5G.
How to Buy a SIM Card in Japan for Tourist
It’s not so easy to buy a SIM card in Japan for tourists. You can make a purchase by credit cards, and such type of cards are issued only to officially working Japanese. However, many tourists bought SIM cards in Japan using debit or prepaid card issued by any banks.
You have to show consultants your passport with a valid visa.
Free Internet in Japan
Wi-Fi in this country can be found at every turn, not only in Tokyo or Osaka, but also in very small cities. Internet is available in all hotels, cafes, libraries, shopping centers, in some park areas. WiFi connection is standard.
The Internet in Japan for tourists is no different from that used by locals. There are no blocked popular resources (Google, Facebook, Instagram).
If you plan to move around the country a lot, but you couldn’t buy a SIM card, then try renting a Wi-Fi router. This is a pocket device that transmits the Internet to several gadgets at once. Renting can be done at mobile phone points. But you will have to pay a deposit for the device – at least 3,000 yen.
At the end of the rental period, the router is returned to the same reception point or sent by mail (shipping cost 300-500 yen). A pocket Wi-Fi will cost 100-150 yen per day.
