The internet has become an essential tool on trips or extended stays in Japan. For example, you can use the net to look up routes on Google Maps or easily apply for specific services.

Those staying in Japan for an extended period should secure an internet service plan with a Japanese provider. But a pocket Wi-Fi router may be a better option for short trips or a stay under a year.

Free Wi-Fi in Japan

Pocket Wi-Fi Router

In recent years, free Wi-Fi spots have cropped up in hotels, cafes, and shopping malls across Japan.

Among the many free Wi-Fi services available, the most famous is an app called Japan Wi-Fi auto connect. Available in 16 languages, it can be used at over 50,000 spots nationwide. The app only connects to Wi-Fi services provided by enterprises or local governments, so it should be relatively safe.

On the other hand, some may want to immediately post photos on their SNS account or use Google Maps while walking.

Free Wi-Fi, which is only available in certain areas, is inconvenient in that regard.

Moreover, users will be sharing a network with an indefinite number of people. It would be wise to avoid disclosing private information, such as one's credit card number.

The Difference Between Pocket Wi-Fi Routers, SIM Cards, and Data Roaming

When it comes to connecting to the internet in Japan, besides installing a fiber-optic internet service at home, there are three options to get online in Japan: pocket Wi-Fi routers, SIM Cards, and data roaming.

Each of them has different features that set them apart.

A pocket Wi-Fi router is a device smaller than a smartphone. It can immediately be used by entering a password.

It offers a large data capacity and can be connected to multiple devices. Therefore, a router can be used during a group trip or when simultaneously using a PC and smartphone.

However, most routers are provided on a rental contract and must be returned when leaving Japan, making it a little bothersome.

SIM Cards

SIM cards are inserted into smartphones. They are inexpensive compared to pocket Wi-Fi routers but lack data capacity.

As of September 2022, Japan Travel SIM by IIJmio, a 1.5 GB card, can be purchased on Amazon for 1,864 yen. Alternatively, a rental router will cost 300 to 1,000 yen daily, so SIM cards are a much more affordable option.

Regarding difficulties with SIM cards, users have to unlock their smartphones and switch out their existing cards. Figuring out the initial settings may be another obstacle, too.

Data Roaming

A data roaming service allows users to use the services of their original provider during international travels. While expensive, it is hassle-free because the user does not have to do anything.

There usually are no restrictions on telephone calls and texting. However, some providers might have limitations in terms of data transfer.

Pocket Wi-Fi Routers and SIM Cards Are Popular Choices

Below is a list of the pros and cons of these three internet options.

Pros A large amount of data will be available.

When visiting Japan, most travelers choose a pocket Wi-Fi router or a SIM card. Please refer to this article when selecting an option that is right for you.

The following are tips for selecting a pocket Wi-Fi router and the various services available.

You can utilize any pocket WI-FI router by following the steps below.

1. Make an online reservation to rent the router.
2. Receive the router at airports, post offices, or hotels in Japan.
3. Return the router upon leaving Japan.

The details vary depending on the provider, so read on to learn about important points when renting a router.

1. Data Capacity, Rental Period, and Billing

Most providers offer unlimited usage (*) or a plan with a restriction of 1 GB per day. The bill changes according to the plan.

Some providers offer a discount for long-term plans, while others do not. The former is ideal for more extended stays, and the latter is fit for a short rental plan. The bill should be around 10,000 yen per month with a long-term discount.

*Even in the case of unlimited usage, the transmission speed might become slow after exceeding 3 GB in one day.

Estimated Data Usage in Japan (1 GB)
E-Mail: 2,090 emails. (500 KB per mail)
Video Viewing: about 4 hours and 16 minutes at medium quality.
Google Maps: about 1,432 views (10 minutes per view).

2. Booking and Receiving the Router

While busily preparing for their trip, most people may forget to book a router.

Many providers ask users to apply three days before receiving the device. There are exceptions, such as NINJA WiFi, which requires only one day. If you are in a hurry, please take advantage of these services.

3. Receiving/Returning the Device at the Airport

In most cases, the router will be sent to your accommodation in Japan (hotel, friend's house, etc.). You can also pick up the rental device at post offices in major airports.

Some providers, such as NINJA WiFi or Sakura Mobile listed below, have a counter at the airport, allowing users to receive the device from the staff. They are located at multiple airports, so first-time users should take advantage of this service.

Users will be asked to send the router back in a bag enclosed in the package or return it to the airport counter.

4. Insurance

A reimbursement fee will be charged if users lose or accidentally damage the router. In the case of Japan Wireless, losing or damaging a router and the inserted SIM card will cost 40,000 yen.

Most providers offer an insurance plan to reduce reimbursement costs. Those visiting Japan for the first time should consider using this service.

Japan Wireless is managed by Inbound Platform, which handles camping cars, along with medical information service for foreign nationals.

The service offers unlimited usage, and the bill changes according to the rental period. As of October 2022, it costs about 1,400 yen a day for short-term rentals and 1,900 yen for two days. This may seem relatively expensive at first glance.

But if the rental period extends over six months, there is a plan with a monthly rate of 5,580 yen. The year-long plan has a monthly rate of 4,980 yen, which makes it cost-effective in the long term. Students planning to study abroad in Japan for an extended period should look at this company.

Japan Wireless also offers an express service so users can receive a router within 24 hours. Those in a hurry should make an inquiry.

Since they do not have a private counter, the router will be sent to an airport post office in Narita (Terminal 1 and 2), Kansai International, Chubu Centrair International, Fukuoka Airport, and the QL Liner counter at Narita Airport. The routers can also be mailed to hotels and private residences in Japan.
