Stores at Narita airport offering prepaid SIM cards/pocket WiFi routers are closed early in the morning and late at night.
There are only a few shops offering them outside of the airport. If you have not reserved before coming to Japan, you will not be able to get a prepaid SIM card easily after leaving the airport.
If you arrive at such time, one of your choices would be purchasing a prepaid SIM card through a vending machine.
Recently, prepaid SIM cards can be purchased through several vending machines at Narita airport, which are available for 24 hours a day.
Prices sold at vending machines are lower than that of shops at the airport.
However, if you want more chaper one, you are better off to go to electronics retail stores such as Yodobashi Camera or Bic Camera outside of the airport.
They sell data only prepaid SIM cards offered by various vendors.
Also, you can buy from Amazonco.jp. They are available for international delivery,so you can receive it before they arrive in Japan.

Prepaid SIM cards sold through vending machines at airports are very useful for international travellers.

If you find that your's is not compatible with the bands or if you have a slightest concern on it, you are better off renting a pocket WiFi router.
We recommend to booking online before coming to Japan.
