Which Pocket WiFi Rental is the Best in Japan 2025?

Are you wondering which pocket WiFi rental company you should choose in Japan? A pocket WiFi is one of the most critical items for traveling in Japan. Let’s compare the prices, device specs, and other services.

A pocket WiFi is one of the most essential items if you are traveling to Japan. You can’t help but use SNSs like Facebook, TikTok, Twitter, and Instagram, search with Google Maps, and talk with WhatsApp and WeChat. It’s hard to travel to foreign countries smoothly without an Internet connection.

I want to find out which pocket WiFi rental company is the best in Japan so you can get the best deal. Spend your travel budget wisely.

Here are the comparisons of 10 popular pocket WiFi rental companies in Japan. Rental rates, data usage amount, data speed, battery life, delivery speed, and how easy to pick up and return are compared under the same conditions:

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

These ten pocket WiFi rental services allow you to pick up a WiFi unit at your hotel, but quite a few people think it’s too difficult to get to their hotels from airports without it. So I believe that pick-up at arrival airports is the most agreeable option.

I think a power bank is as necessary as a pocket WiFi router. If you connect to the Internet all day, the battery of the WiFi router is fully drained. What do you think if you run out of battery and cannot find a restaurant for dinner? Take one mobile battery, at least in Japan.

For those looking to rent unlimited pocket WiFi

The use of WiFi has become more diversified today, not only for using 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 usage during a trip to Japan, many people may not want to worry about data limits. Hence, the preferable choice would be a service that offers unlimited data usage.

In Japan, there are numerous companies offering 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 use of communication, but once a certain amount of data is used 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 there’s a potential for restrictions due to excessive use under the label of “unlimited”. Pay attention to this detail when choosing your rental pocket WiFi.

For those seeking long-term pocket WiFi rentals

For those on long-term travels lasting several months, or for longer stays due to business trips or studying abroad, it would be beneficial 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 has Premium WiFi – Super Long Plan for rentals of over six months, allowing you to rent Unlimited WiFi at less than half the regular price. Additionally, Wi-Fi Rental Store offers advantageous plans for each of their packages starting from one month. Those interested in long-term rentals should check this out: Best Long-Term Pocket WiFi in Japan.

Furthermore, for those moving to Japan, it might 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 important to note that it’s not necessarily convenient and easy to use for everyone. This can be particularly challenging for tourists from abroad.

First of all, there are limitations on usage time and data, unstable connection speeds, and the hassle of having to sign up every time you access the Free WiFi network. These are the main issues with using Free WiFi. It’s problematic when the connection is cut off every 30 minutes or the data speed is extremely slow, especially since travelers often need to quickly look up information or communicate.

If Free WiFi is unavailable, switching to international data roaming is the only alternative, which can end up being 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, it’s recommended to rent a pocket WiFi. The most significant reason is the data usage and speed. Nowadays, with the diversification of devices such as smartphones, tablets, and PCs, there’s a demand for internet connectivity in various situations. A pocket WiFi, especially those offering unlimited data services, allows you to use WiFi freely without worrying about limitations.

On the other hand, most SIM cards offer significantly less data usage compared to pocket WiFi. Moreover, there are usage limits set for either a day, a month, or both. If you are someone who only needs minimal internet access, a SIM card might be cheaper.

However, compatibility issues with your device remain a concern with SIM cards. Also, nowadays, services like eSIM are available, which don’t require a physical SIM card.

In any case, if you want to be as free as possible from all the limitations of WiFi usage and have a smooth journey, consider renting a pocket WiFi.

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

With recent WiFi devices, in most cases, 5 to 10 people can connect to one device simultaneously. However, as the number of smartphones or PCs connected at the same time increases, the speed can become slower, and battery consumption may be more intense. Therefore, using it with the maximum number of simultaneous connections isn’t very practical.

Ideally, it’s recommended to use one device for every 2-3 people. But if you often split up from your travel companions or if there are more people to travel with, it’s better to rent multiple devices. The smooth usage of WiFi offers convenience that can’t be substituted with money.

Should you take insurance with your pocket WiFi rental?

Do you worry about loss or damage of your pocket WiFi? You just maybe drop a WiFi router on the ground or have it stolen though Japan is a safer 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 an insurance to avoid being charged for much more expensive compensation fee than the amount of WiFi rental fee.

Particularly if you want to enjoy outdoor activities or are aware that you tend to forget things, it is reassuring to take out insurance just in case, so you can travel with peace of mind. As none of the companies charge excessively high fees, it’s especially advisable for those renting WiFi in Japan for the first time to add insurance for added security.
