Many pocket Wi-Fi plans in Japan have limited data capacity, but there are some that offer nearly unlimited data. In this article, we will introduce 5 unlimited pocket Wi-Fi services in Japan that are recommended for foreigners.

What is Unlimited Pocket Wi-Fi?

As of 2022, there are very few pocket Wi-Fis in Japan that are completely unlimited, and even if they are written as "unlimited,"In reality, there are often some restrictionsis. First, in this chapter, we will explain what unlimited pocket Wi-Fi means.

Unlimited monthly total capacity

The most common type of unlimited pocket Wi-Fi is the type where the total monthly capacity is unlimited, but the amount of data per day or three days is limited. With this type, if you use too much capacity in one day, your speed will be restricted for a certain period of time.

Large capacity virtually unlimited for most people

The next most common type has a very large capacity, such as 100G per month, so most people never run out of capacity and can use it virtually unlimitedly. This actually has an upper limit, so it has a different meaning from a completely unlimited limit like fiber optic lines.

Unlimited within a fixed area

Rakuten Mobile's Wi-Fi uses a system that is unlimited only when using Rakuten's line. Rakuten's Wi-Fi also uses other companies' lines, so there are restrictions only when using other companies' lines.

What is the price range for unlimited pocket WiFi in Japan?

The price of unlimited pocket WiFi varies greatly depending on the plan, but rentals start at around 1,000 yen for one day, and can go as low as 300 yen per day if rented for a longer period, such as 30 days.

Monthly plans vary depending on the provider, but low-cost plans can cost around 3,000 yen a month, and expensive ones can cost around 7,000 yen.
