Free WiFi situation in Japan and how foreigners can use the Internet

Japan is one of the world's largest economies and one of the most technologically advanced countries. However, the penetration rate of free Wi-Fi in public places is still low compared to other developed countries such as Europe, the United States, South Korea, and China. According to a survey by the Ministry of Internal Affairs and Communications, Japan's public wireless LAN coverage rate is the lowest among major developed countries.

Services such as Japan Connected-free Wi-Fi provided by the Japan Tourism Agency and Wi-Fi spots provided by major telecommunications carriers are available, but they are not yet sufficient. Especially in regional cities, it is sometimes difficult to find free Wi-Fi. For foreign travelers, this situation may seem inconvenient.

However, there are several other ways to access the Internet in Japan besides using free Wi-Fi. Here are four main ways for foreigners to use the Internet in Japan.

Use Japan.Free Wi-Fi provided by the Japan Tourism Agency

Japan. Free Wi-Fi" provided by the Japan Tourism Agency is a free public wireless LAN service for foreign visitors to Japan. It is available at more than 30,000 locations nationwide, including airports, train stations, tourist information centers, and commercial facilities.

Reference:Free Wi-Fi

2. use the free Wi-Fi available at the facility

Many restaurants, shopping malls, and lodging facilities offer free Wi-Fi service. These establishments often have Wi-Fi information posted inside the store.

The connection method varies from facility to facility, but in general, you must select the appropriate SSID from the Wi-Fi settings screen and enter your password or register your e-mail address.

Some facilities offer free Wi-Fi services for foreign visitors. For example, "Lawson Wi-Fi" is a free Wi-Fi service available at Lawson stores and is known as a service for foreign visitors to Japan.

3. use Wi-Fi connection application 【 free or paid 】

There are also application services that allow you to easily search for and connect to free Wi-Fi spots in Japan. They range from free to fee-based services.

For example.Town WiFiis a free Wi-Fi connection application. It automatically connects to approximately 200,000 free Wi-Fi spots nationwide. It supports not only restaurants and commercial facilities, but also public Wi-Fi such as "XX City Free Wi-Fi" provided by the local government.

The paid application service is called "Wi2 300is a typical example. For 362 yen per month (excluding tax), you can use about 800,000 Wi2 spots nationwide. There is also a prepaid plan for foreigners, the Passport, which costs 1,340 yen (excluding tax) for 14 days.

4. use pocket Wi-Fi or prepaid SIM

If you have trouble finding free Wi-Fi or want a more secure and stable Internet environment, pocket Wi-Fi or prepaid data communication SIM cards are recommended.

Pocket Wi-Fi, also called a mobile Wi-Fi router, is a small device with a built-in SIM card that provides Wi-Fi connectivity using mobile data communications. It is a convenient way to connect multiple devices such as smartphones, tablets, and PCs to the Internet while on the go.

A prepaid data communication SIM card is a service that allows you to purchase a data allowance in advance and use it only for the amount of data you need.

In Japan, there are companies that offer pocket Wi-Fi rental services and prepaid SIM cards for foreign travelers. Let's take a closer look below.

How much does pocket Wi-Fi cost in Japan?

There are two main options for using pocket Wi-Fi in Japan. One is to subscribe to a monthly service, and the other is to use a rental service for short-term use.

For monthly subscriptions, the price varies depending on the provider and device specifications, but plans with a data allowance cap range from 3,000 yen to 4,000 yen per month. Examples include UQ WiMAX and WiMAX2+ from major telecommunications carriers.

On the other hand, unlimited data plans generally cost between 4,000 yen and 6,000 yen per month. Examples of unlimited plan services include "Dokoyore WiFi" and "ZEUS WiFi," which will be discussed later in this article.

Pocket Wi-Fi rental services are often priced on a per-day basis. Rates range from 500 yen to 1,000 yen per day, and the longer the period of use, the lower the daily rate: around 4,000 yen for 7 nights and 8 days, and around 15,000 yen for 30 nights and 31 days.

WiFi Rental Dotcom and Global WiFi, which will be introduced later, are also popular Wi-Fi rental services for foreign tourists.

However, please note that some providers require a deposit at the time of rental, or may charge additional fees for optional services. It is important to carefully check service details and select a plan that meets your needs.

Pocket Wi-Fi or SIM card?

Pocket Wi-Fi and SIM cards are both convenient means of Internet access. Understand the features of each and choose the one that best suits your needs.

The biggest advantage of pocket Wi-Fi is that a single device can share a Wi-Fi connection with multiple devices. You can connect smartphones, tablets, laptops, and other devices in various situations on the go, such as at your lodging or in a moving car. Another key point is that it is easy to set up, so even people who are not familiar with the machine can use it. Even if you do not understand Japanese, you can rest assured that many services provide detailed explanations at the time of rental.

A SIM card, on the other hand, allows mobile data communication simply by plugging it into a smartphone, making it easy to use. Like pocket Wi-Fi, there is no need to carry around a separate device, and a single smartphone is all you need. Also, many of them are prepaid, so you can choose flexibly according to the amount of data you need. The fee structure is simple and easy to understand, so the risk of high bills due to overuse is minimized.

Nevertheless, each is not suitable for everyone, so the following points should be taken into consideration when making your choice.

Who is suited for pocket Wi-Fi?

  • Often works with a family or group rather than alone
  • I want to have internet access at my accommodation.
  • Frequent use of tablets and PCs in addition to smartphones
  • I want to focus on signal strength and speed.

Who the SIM card is suitable for

  • Traveling alone or traveling style with a lot of movement
  • I want to carry as little luggage as possible.
  • I want to use the Internet right away with a simple setup.
  • I want to freely choose the duration and the amount of communication.

We recommend that you take the above points into consideration and choose the one that best suits your travel style. Please also check the following article for a more detailed explanation of SIM cards.

Check the communication speed when choosing pocket Wi-Fi.

When choosing a pocket Wi-Fi, along with price and service area, communication speed is also an important point to check.

Pocket Wi-Fi speeds are expressed in two metrics: downlink (download) and uplink (upload). Generally, the downlink speed is more important than the uplink speed.

If you see the notation "00Mbps downlink," you can consider that to be the approximate download speed. The higher this number is, the faster you can download large amounts of data.

Pocket Wi-Fi tends to have faster downlink speeds than SIM cards.

However, the specific speed required depends on the usage scenario. Please refer to the following guidelines.

Online games require 30 Mbps or more

Online games that require real-time communication require fast and stable communication speeds. For competitive games in particular, a downstream speed of 30 Mbps or higher is desirable.

Upload speed is also important during gaming. Since operation information needs to be sent to the server quickly, the uplink speed should be at least 10 Mbps.

About 10Mbps to 20Mbps for video viewing and web conferencing

When using video streaming services such as YouTube and Netflix, or web conferencing such as Zoom and Skype, downlink speeds of 10Mbps to 20Mbps can be used without significant delay.

If you want to maximize the quality, an even higher speed is desirable, but for medium quality settings, this level of speed will work fine.

About 1 Mbps is sufficient for browsing sites, e-mail, and LINE.

If you are just browsing websites with mostly text and images, such as news sites and blogs, you should have no problem with a downlink speed of about 1 Mbps.

Communication tools such as e-mail and LINE also do not require very high transmission speeds if texting is the main focus.

While taking the above points into consideration, it is recommended that you choose a pocket Wi-Fi with sufficient speed for your needs, assuming the Internet services you frequently use.

Check not only the speed, but also the service area, price, and battery life comprehensively to find the right one for you.
