We have counters at most major airports in Japan, so you can pick up your router and start using the internet as soon as you arrive. The counter in Shinjuku Tokyo is a great option for anyone who has already arrived and realized they want WiFi now. Or you can choose to pick up via delivery services so you don't have to spend time wandering around the airport/Tokyo trying to find one of our counters. Mix and match pick-up and return locations to match your travel plans.

SIM? Roaming? A Mobile WiFi router?

Other methods of Internet connection are necessary in Japan, because you can’t rely on free WiFi services.

Prepaid SIM card
SIMカード
SIM cards are not easy to set up, especially for those not used to the system. Also, since you cannot use a SIM card with more than one device, it can be incovenient for anyone travelling with friends or family who also wish to use the internet. And even those who still think a SIM card is better for them still risk losing their original SIM while they are using their new SIM in Japan.
Roaming
Roaming
Roaming is convenient because you do not need to replace your SIM card or carry a WiFi router with you, but it’s very expensive. You must be careful not to connect with the wrong telecommunications carrier or you will be billed with a hefty fee. Also, in many cases, transmission rates in high traffic areas slow down so much that you can’t use the internet at all.
