Are you wondering which pocket WiFi rental company to choose in Japan? A reliable Internet connection can make traveling around Japan much easier, from navigating with Google Maps to finding restaurants and staying in touch with friends and family. Let’s compare popular pocket WiFi services in Japan by price, device specs, data plans, and other useful features.

A pocket WiFi can be one of the most useful items when traveling in Japan. You may need the Internet throughout the day to use social media such as Instagram, TikTok, Facebook, and X, navigate with Google Maps, or communicate through apps such as WhatsApp and WeChat. Traveling in a foreign country can be much more difficult without a reliable Internet connection.

So, which pocket WiFi rental service is best for your trip? To help you choose and spend your travel budget wisely, we have compared some of the most popular pocket WiFi rental services available in Japan.

The comparison covers rental rates, data allowances, theoretical data speeds, battery life, pickup and return options, and how far in advance you need to order. To make the comparison as consistent as possible, prices are based on the following conditions:

• Pick-up Location: Airport
• Rental Term: 14 days
• Option: Extra mobile battery

Airport pickup is especially convenient because having Internet access as soon as you arrive can make the journey to your accommodation much easier. Instead of waiting until you reach your hotel, you can immediately use maps, check transportation information, or contact your accommodation if necessary. Please note that airport pickup availability and ordering deadlines vary by provider.

A mobile battery can also be useful if you plan to stay connected throughout the day. Pocket WiFi battery life varies considerably between devices, and heavy use can drain the battery before you return to your accommodation. A power bank gives you extra peace of mind when you still need WiFi for directions, restaurant searches, or communication later in the day.

For those looking to rent unlimited pocket WiFi

WiFi use has become more diverse today, not only for map apps and search engines on smartphones and tablets but also for watching videos, playing games, uploading photos and videos to social media, and communicating with friends. For stress-free WiFi use during a trip to Japan, many people don’t want to worry about data limits. So, the best choice is a service that offers unlimited data.

In Japan, many companies offer unlimited pocket WiFi, but it’s important to note that there are two types of “unlimited.” One is a “completely unlimited” service, which allows unlimited data usage at a stable speed, as the name suggests. The other type offers unlimited communication, but once you use a certain amount of data in a day or month, the speed becomes extremely slow. This latter type of “unlimited” can be problematic as the data speed may become so slow that it’s practically unusable.

The services introduced in this article clearly indicate whether they are truly unlimited or if they may restrict use under the label of “unlimited.” Pay attention to this detail when choosing a pocket WiFi rental.

For those seeking long-term pocket WiFi rentals

For long-term travel lasting several months, or for longer stays due to business trips or studying abroad, it helps to look for long-term rental plans. Many companies offer pocket WiFi at significantly reduced rates for rentals spanning a few months to over half a year.

For instance, Japan Wireless offers a Premium WiFi – Super Long Plan for rentals over six months, letting you rent Unlimited WiFi for less than half the regular price. Additionally, Wi-Fi Rental Store offers advantageous plans for each package, starting from one month. Those interested in long-term rentals should check this out: Best Long-Term Pocket WiFi in Japan.

Also, if you’re moving to Japan, it may be a good idea to contract with an internet service provider and install a home router. Here is a compilation of popular internet services.

Can you use Free WiFi in Japan?

Like many countries, Japan offers Free WiFi environments in public places. However, it’s not always convenient or easy for everyone. This can be particularly challenging for tourists from abroad.

First, usage time and data are often limited, connection speeds are unstable, and you may have to sign up every time you access the Free WiFi network. These are the main issues with using Free WiFi. It’s especially problematic when the connection cuts out every 30 minutes or the data speed is extremely slow, since travelers often need to quickly look up information or communicate.

If Free WiFi is unavailable, international data roaming is the only alternative, and it can be quite costly.

Moreover, while hotels and some public facilities might offer practical Free WiFi, the real need for internet access often arises when you are out and about. Additionally, security concerns are a common drawback of Free WiFi, regardless of the country.

For these reasons, when traveling in Japan, it’s wiser not to rely on Free WiFi and instead rent a pocket WiFi device.

In Japan, which is recommended: a pocket WiFi or a SIM card?

To conclude, renting a pocket WiFi is recommended. The main reason is data usage and speed. Nowadays, with the growing use of devices such as smartphones, tablets, and PCs, many situations require internet connectivity. A pocket WiFi, especially one offering unlimited data, lets you use WiFi freely without worrying about limits.

On the other hand, most SIM cards offer significantly less data than pocket WiFi. Moreover, usage limits are set daily, monthly, or both. If you only need minimal internet access, a SIM card might be cheaper.

However, SIM cards can still cause compatibility issues with your device. Also, services like eSIM are now available and don’t require a physical SIM card.

In any case, if you want to avoid WiFi limitations and have a smooth journey, consider renting a pocket WiFi.

When traveling with multiple people, is one pocket WiFi device enough?

Most recent WiFi devices can connect 5 to 10 people to one device at a time. However, as more smartphones or PCs connect at the same time, speeds can slow, and battery consumption can increase. Therefore, using it with the maximum number of simultaneous connections isn’t very practical.

Ideally, use one device for every 2-3 people. But if you often split up from your travel companions, or if you’re traveling with more people, it’s better to rent multiple devices. Smooth WiFi use offers convenience that money can’t buy.

Should you take insurance with your pocket WiFi rental?

Do you worry about losing or damaging your pocket WiFi? You might drop a WiFi router on the ground or have it stolen, even though Japan is a safe country. Some companies offer insurance options which cover full compensation or a part of it like 50%, 75%.

Just in case, it is recommended to take insurance to avoid being charged a much higher compensation fee than the WiFi rental fee.

Especially if you want to enjoy outdoor activities or tend to forget things, insurance can be reassuring so you can travel with peace of mind. Since none of the companies charge excessively high fees, first-time WiFi renters in Japan should add insurance for added security.

Conclusion

The best pocket WiFi depends on what you want to do with WiFi in Japan; however, it is definitely better to choose unlimited data usage at an affordable rate. Easy pick-up and return services will also help you in a strange country. During the rental period, all you need to do is put the package in a post box or post office anywhere in Japan.

There are many pocket WiFi rental services in Japan, so you may be unsure which one to choose; please refer to the recommended services above and choose the one that best suits your needs.

Have a wonderful trip to Japan, and stay connected with these useful pocket WiFi devices!
