Get UbigiPocket WiFi or eSIM in Japan?
For one or two travelers with recent phones, get an eSIM rather than a pocket WiFi. Ubigi's 10 GB costs about $16.50 for the trip, with no router to collect or post back. A pocket WiFi still makes sense for a family sharing one connection all day, or a phone that can't take an eSIM.
If you buy through a button here, the provider pays me a commission. Your price stays the same.
No eSIM yet? The one to buy for your trip.

Pocket WiFi vs eSIM in Japan, side by side
The router and the eSIM both give you mobile data in Japan. The difference is in the extra things a router asks of you.
| What changes | eSIM | Pocket WiFi |
|---|---|---|
| What you carry | Nothing extra | A router, a power bank and cables |
| Getting it | Install at home on Wi-Fi | Airport pickup or hotel delivery |
| Battery | Your phone's | About 8 to 10 hours |
| Devices | One phone, more with hotspot | Up to 8 at once |
| Giving it back | Nothing to return | Post it the day after the rental ends |
| If it's lost | Nothing to lose | A replacement fee, unless you add protection |
Router details come from Japan Wireless, one of the main rental companies. A late return is charged, and a hotel delivery needs the hotel's name and your booking.
When a pocket WiFi is the better pick
A router still earns its place on three kinds of trip.
A family or group on one connection
Four people with phones and tablets, together all day, can share one router. Separate eSIMs mean four purchases and four installs. A router is billed by the day, so compare its quote with about $16.50 per traveler.
A phone that can't take an eSIM
An older or carrier-locked phone can't add an eSIM. A router works with any device that has Wi-Fi.
Laptops and tablets for work
A router doesn't drain your phone to share data. If you'd rather share from your phone, Ubigi and Nomad allow hotspot, while Holafly limits sharing to 1 GB a day.
The eSIM to get instead
For one or two people, one of these three fits most Japan trips.
| Trip | eSIM | Price |
|---|---|---|
| Most trips, up to a month | Ubigi, 10 GB, 30 days | $16.50 |
| Heavy use, 10 days | Saily unlimited, 5 GB a day at full speed | $34.99 |
| Sharing with a laptop | Nomad, 50 GB, 30 days | $35.00 |

On Ubigi, users report a Japanese IP address, so apps see you in Japan. Its networks and plans are in the Ubigi review. For heavy use, the Saily eSIM review explains how its unlimited plans work.
Get Ubigi for JapanIf you rent a pocket WiFi: pickup and return
How it works at Japan Wireless, from order to postbox.
1Before you fly
Order and pick where to collect it
Choose an airport counter or delivery to your hotel, where it arrives before check-in. Ordering late? Same-day pickup at the airport counter is possible.
2When you land
Turn it on and connect
Join the router's Wi-Fi with the password on its label. Keep the power bank charged for long days out.
3The day after the rental ends
Drop it in a postbox
A prepaid return envelope comes in the package. Late returns are charged.
Japan Wireless doesn't deliver to an Airbnb. Staying in a rental apartment, collect the router at the airport.
Pocket WiFi and eSIM questions
Do you still need pocket WiFi in Japan?
Not if your phone takes an eSIM. Install one at home, and you have data when you land at Narita or Haneda, with no counter to find. A router still helps a group that wants one shared connection.
Is pocket WiFi still worth it?
For a family of four with phones and tablets, it can be. Japan Wireless says its routers connect up to 8 devices at once. For one or two people, an eSIM such as Ubigi at about $16.50 does the job with nothing to carry.
What is the best portable WiFi for traveling?
Your own phone, with an eSIM that allows hotspot. In Japan, Nomad's 50 GB plan allows it, for about $35.00. Holafly's unlimited plan limits sharing to 1 GB a day.
