What is Unlimited Pocket Wi-Fi? How the service works explained
As of 2024, most Japanese pocket Wi-Fi services do not offer completely unlimited plans, and in most cases, even when the term "unlimited" is used, there are actually some restrictions in place. Therefore, this section will first provide a detailed explanation of the reality of unlimited pocket Wi-Fi services in Japan and the meaning of the claims made in advertisements.
Unlimited total monthly capacity
The most common type of unlimited pocket Wi-Fi is the type that has unlimited total monthly capacity but a limit on the amount of data per day or per 3 days. With this type, if you use too much capacity in a day, the speed will be limited for a certain period of time. However, there is no limit on the total monthly capacity, so there is no problem if you use a little data communication every day.
High-capacity plans offer virtually unlimited use.
The next most common type is one in which the capacity is so large, such as 100 GB per month, that most people never run out of capacity and can use it as if it were virtually unlimited. Unless you are a frequent video streaming user, 100GB per month is sufficient capacity. This also has an upper limit, so it is not the same as a completely unlimited service like an optical fiber line, but for general use, it can be used without any problems.
Unlimited only within a defined area
The system used by Rakuten Mobile Wi-Fi is unlimited only when using Rakuten's line. Rakuten's Wi-Fi is also used in conjunction with other companies' lines, so you will only be limited when using other companies' lines. In other words, you can use it as much as you want as long as you are within the Rakuten line area, but be aware that your traffic will be counted once you go outside the area.
What is the price range for unlimited pocket WiFi in Japan?
So here are five unlimited pocket Wi-Fi in Japan that we recommend for foreigners.
Prices for unlimited pocket WiFi vary widely depending on the plan, but rentals can be as low as 1,000 yen for one day and as high as 300 yen per day if rented for longer periods, such as 30 days.
Monthly plans vary from provider to provider, but a low monthly plan may cost as little as 3,000 yen and a high monthly plan may cost as much as 7,000 yen.

Since you only pay for what you use, you will be able to use the service without wasting money.

Comparing Pocket Wi-Fi and SIM Cards｜Wi-Fi is best for multiple devices
We have looked in detail at pocket Wi-Fi, but there is also the SIM card option, which plugs directly into your smartphone and does not require you to carry a separate device like pocket Wi-Fi. If mobility is important to you, you may want to consider a SIM card.
However, a SIM card can basically be inserted into only one device. If you use multiple smartphones, tablets, PCs, etc., you will need SIM cards for the number of devices, which will also increase the cost. When multiple people are using the same device, such as on a family vacation or business trip, pocket Wi-Fi is convenient because multiple devices can connect to the Internet with a single device. In total, pocket Wi-Fi will be cheaper.
