Last Minute WiFi Rental

I missed the deadline to book and reserve a wifi router to pick up at Haneda Airport. Is it possible to just go to the counter at the airport to just rent one? And which company to rent from?

Thank you in advance

Almost all the rental kiosks do same day rentals subject to availability. The list of rental operators is listed here:

Just take note that you can only use credit card to pay for router rental from the service counter at the airport. No debit cards or cash allowed. As for prepaid data card, you can use cash.

Depending on your stay in Japan, you can also have them to send it to your staying Hotel once one is available right away.

Thank you everyone! I managed to get one router at the counter.
