Super Easy: How to Return Pocket WiFi in Japan

For many international travelers visiting Japan, Pocket WiFi is one of the most popular and convenient ways to stay connected. It’s reassuring to stay online during your trip—for using maps, translation apps, or posting on social media. While more people are now using eSIMs and SIM cards, Pocket WiFi is still the most popular option.

Why is Pocket WiFi so popular?

Even though more travelers are using SIM cards and eSIMs, there are three main reasons why Pocket WiFi remains a top choice.

1. Easy to Use

Some smartphones may not support Japanese network frequencies, especially if they are not sold in Japan. This can lead to problems like not being able to connect in rural areas, even if they work fine in cities. Pocket WiFi devices are made for use in Japan, so you don’t have to worry about compatibility. Just turn it on, and you're online. You can also connect any Wi-Fi-enabled device.

2. Large Data Plans

Pocket WiFi is designed to be shared by multiple devices, so it comes with large data limits. Some services even offer unlimited data, which makes it perfect for families and groups. Many devices also support 5G and provide a stable connection.

3. Great Value

You can save money by sharing one Pocket WiFi among multiple people. It’s a cost-effective solution.

Since Pocket WiFi is rented, it must be returned

Pocket WiFi is simple and offers large data usage, but because it's a rental, many travelers who are unfamiliar with Japan worry about the return process.

Returning Pocket WiFi is Easy!

You might think “Returning Pocket WiFi sounds troublesome” or “I don’t understand Japanese, so I won’t know how to return it.” But actually, it’s very simple. Most services that offer Pocket WiFi in Japan provide a Letter Pack for return shipping. Even if you don’t understand Japanese, you can return it in just a few seconds.

Return via Letter Pack

• Returnable from anywhere in Japan
• Just drop it into a mailbox
• Mailboxes are near airports, stations, and hotels
• Comes with a tracking number for peace of mind

Simply place the Pocket WiFi into the Letter Pack included with your rental and drop it into a mailbox. That’s it!

Where do most people return it from?

Return from the airport (most common)

Most travelers return their Pocket WiFi via a Letter Pack dropped into a mailbox at airports like Narita, Haneda, or Kansai International Airport.

Return from a city mailbox

Some people return it from mailboxes near stations or hotels. You can also find mailboxes easily in tourist areas. It's convenient to return it before heading to the airport.

Note: Don’t ask the hotel front desk to return it

Some hotels may not ship it right away, which could result in late returns and extra charges. For a safe return, it’s best to put it in the mailbox yourself.
