2025 Ultimate Guide to Portable Pocket WiFi, eSIM, and SIM Cards for Japan

Airport Pickup and Rental Guide

At major airports in Japan (such as Narita, Kansai, and Haneda), you can easily rent portable WiFi devices and eSIMs to ensure you stay connected throughout your trip. While most airports have rental counters for mobile WiFi, we recommend pre-booking online due to the high rental prices at the counters and the limited stock available. You can opt to have your rental delivered to the airport post office or pick-up counter for a smooth experience. Of course, if your flight arrives in Japan at a time that doesn’t allow for enough time to collect your rental at the airport post office or counter, you can also choose to have your WiFi device or SIM card delivered to your hotel or another accommodation. Whether you pick up your WiFi device at the airport or at your hotel, you'll have a convenient option to get connected as soon as you arrive in Japan.
