Wi-Fi is indispensable when using smartphones and tablets. In Japan, free Wi-Fi is becoming more available at airports and hotels, but there are still not many locations in the city that offer free Wi-Fi.

Therefore, we recommend renting a pocket Wi-Fi or SIM card when traveling to Japan.

Pocket Wi-Fi and SIM cards each have their own advantages and disadvantages. In this article, we introduce pocket Wi-Fi routers that are especially recommended for short-term trips or long-term stays in Japan.

For information on the differences between pocket Wi-Fi and SIM cards, as well as the situation of free Wi-Fi in Japan, please check the Frequently Asked Questions at the end.

    How to Rent a Pocket Wi-Fi Router in Japan

    Which Pocket WiFi Router Is The Best? Top 7 Companies In Price, Data, And Rental

    Photo by Pixta
    How do you rent a pocket Wi-Fi router in Japan? Please note that most bookings must be made in advance online. Some companies offer same-day rentals, but you may be unable to rent a portable Wi-Fi router if there are limited quantities. Make sure to reserve in advance, so you can connect to the Internet upon arriving in Japan.

    When picking up your device, you can head to one of the vendor's airport counters or visit a store location in the city. Some vendors also offer delivery pick-up to your hotel or a designated address.

    There are several options when returning your device. You can directly return your pocket Wi-Fi at the airport counter or one of the store locations. Mailing the device from a convenience store is also an option. Please choose the method that best suits your needs.

    You must pay a compensation fee (about 40,000 yen) if the device is damaged or lost. Opt-in for the company's optional insurance to feel more at ease.

    There are many pocket Wi-Fi services available for visitors to Japan. You may actually think, "There are too many options! I don't know which one to choose!"

    At MATCHA, we have researched various services focusing on price and available data capacity. Among them, we have selected and introduced four services with excellent benefits for short-term stays ranging from one day to one month.

    Among them, we particularly recommend Ninja Wi-Fi, which is not only affordable but also offers a good balance of data capacity. However, each service has its own strengths, so please choose according to your own needs.

    1. NINJA Wi-Fi: The Cheapest Service for One to Two Weeks!


    Picture courtesy of NINJA Wi-Fi

    NINJA Wi-Fi is the best choice for trip of about one to two weeks. This service is provided by Vision, a well-established internet service company known for its Global WIFI brand.

    Ninja Wi-Fi's basic plan offers a daily limit of 3 GB for 770 yen. Furthermore, if you apply through MATCHA, you can get a 20% discount, bringing the cost down to 616 yen per day! As far as our research indicates, this is the cheapest option in Japan for a trip of about one to two weeks.

    In addition, Ninja Wi-Fi operates on the Softbank 4G LTE network, ensuring smooth video streaming without any hassle.

    Another notable feature is that Ninja Wi-Fi has a large number of pick-up counters compared to other services. In addition to their office in Shinjuku, they have counters at all the major airports in Japan, including Narita, Haneda, Hokkaido (New Chitose, Asahikawa), Fukuoka, Osaka (Kansai International Airport), Nagoya (Chubu Centrair International Airport), Ishikawa (Komatsu Airport), Kagoshima, and Okinawa (Naha).

    Particularly at Tokyo's Narita and Haneda airports, Kansai International Airport, and Naha Airport, you can pick up the device if you apply by 3:00 PM (Japan time) the day before.

    Furthermore, Ninja Wi-Fi offers additional options such as insurance that combines medical services in Japan with coverage for Wi-Fi device malfunctions, as well as rentals for mobile phones and translation devices that can be used in Japan.

    Read the article below for more details on NINJA WiFi.

    2. Japan Wi-Fi rental: The Cheapest Service for More Than Two Weeks

    If you're looking for an affordable pocket Wi-Fi and plan to use it for longer than two weeks, the cheapest option is Japan Wi-Fi rental, according to MATCHA's research.

    Their basic plan is only 430 yen/day for 612 Mbps (monthly limit of 50 GB, Softbank network). However, there are separate charges for the charger (550 yen) and shipping for pick-up and return (1,100 yen), making it more expensive than Ninja Wi-Fi for stays that are shorter than two weeks. However, if you rent it for longer than two weeks, it becomes a more cost-effective option.

    With a monthly data limit of 50 GB, if you rent it for a month, you'll have approximately 1.6 GB per day. However, as mentioned in the FAQ at the end, depending on your usage, even 1 GB/day may be sufficient. If you don't need a large amount of data, this option may be suitable for you.

    You can pick up the device offered by Japan Wi-Fi rental at the airport's post office, or have it delivered to hotels, inns, or a friend's place. Returns can be done by simply dropping it in the mailbox. In case of loss, there will be a charge of 16,500 yen for the device and a contract termination fee of 19,800 yen.

    3. Japan Wireless: No Concerns about Fata Capacity!

    Many pocket Wi-Fi services either stop working or impose speed limitations once you reach a certain data usage limit.

    In contrast, Japan Wireless offers a unique plan where the data usage is unlimited (without speed limitations), but the speed is limited based on the chosen plan.

    They offer three plans: Unlimited data with a speed of 95 Mbps, Unlimited data with a speed of 120 Mbps, and Unlimited data with a speed of 187 Mbps (*).

    However, it's worth noting that Japan Wireless is slightly more expensive. For example, the Unlimited data with a speed of 95 Mbps plan costs 4,780 yen for one week (compared to 4,312 yen for Ninja Wi-Fi's daily 3 GB plan with a discount). The Unlimited data with a speed of 187 Mbps plan costs 7,960 yen for one week.

    While the rental cost decreases as the rental period gets longer, if cost is the main concern, it may be better to choose Ninja Wi-Fi or Japan Wi-Fi rental.

    The advantage of using Japan Wireless, however, is that there are no speed limitations regardless of data usage. For those who prioritize worry-free usage without considering the cost, Japan Wireless is a recommended service.

    *For reference: The aforementioned Ninja Wi-Fi is said to have a maximum speed of 187Mbps.

    4. eConnect Japan: A Unique Plan with No Data Limit!

    eConnect Japan

    Alongside Japan Wireless, eConnect Japan also offers a unique plan. Its distinctive feature is that it provides the same data capacity regardless of the usage period.

    eConnect Japan offers plans with 20 GB, 50 GB, and 100 GB (all with a speed of 187.5 Mbps on the Softbank network). While the prices are often higher compared to Ninja Wi-Fi, it can be a good deal if you want to use more than 10 GB in a short period of time.

    Please note that the rental fees for eConnect Japan vary depending on the rental period. As of October 2023, the price for renting the 20 GB plan for one week was 4,900 yen, while for four days it was 4,500 yen. It may be slightly more expensive compared to Ninja Wi-Fi and Japan Wi-Fi rental, so please take that into consideration.

    FAQ: Frequently Asked Questions

    We have compiled a list of frequently asked questions about pocket Wi-Fi services.

    Q1. How do I set up a pocket Wi-Fi?


    Simply go to the "Settings" menu on your smartphone, select "Wi-Fi," click on the Wi-Fi network you want to connect to, and insert the password.

    *Please note that the setup may vary depending on the device model.

    Q2. Which is better, a SIM card or a pocket Wi-Fi?

    When using the internet in Japan, in addition to pocket Wi-Fi, using a SIM card that can be inserted directly into your smartphone is also popular.

    SIM cards have several advantages that pocket Wi-Fi does not offer.

    First, SIM cards are inserted directly into smartphones, eliminating the need to carry a separate device like a Wi-Fi router. This makes them more convenient and reduces the risk of damaging or losing the device (additional fees may apply for damaged or lost Wi-Fi routers).

    Furthermore, in recent years, eSIM has also been introduced, which allows you to use it immediately with just online procedures. While you need to pick up a Wi-Fi router at places like airports or hotels, eSIM eliminates this requirement.

    However, using a SIM card can be inconvenient as it requires opening the smartphone's SIM card slot to swap cards. Additionally, some eSIM services may not allow tethering with other computers or smartphones.

    On the other hand, pocket Wi-Fi is easy to set up and can be easily connected to multiple computers and smartphones, making it more convenient.

    Both options have their own merits and drawbacks, so please consider which one suits your needs best.

    Q3. How much data do I need during my stay in Japan?


    Photo by Pixta

    The amount of data you will need varies depending on the individual, but please consider the following guidelines:

    If you use free Wi-Fi at hotels or cafes for data-heavy activities like video streaming, even a small data plan should be sufficient to enjoy your trip to Japan.

    However, troubles can arise during international travel. If you're not very experienced with traveling, it is recommended to have a service that provides at least 1 GB of data per day.

    Estimated data usage in Japan (what you can do with 1 GB):
    Sending emails: approximately 2,090 emails (assuming each email is about 500 KB)
    Video streaming: Approximately 4 hours and 16 minutes of medium-quality video
    Google Maps: Approximately 1,432 views (assuming each view lasts for 10 minutes)

    Reference: Wi-Fi

    Q4. Is free Wi-Fi reliable in Japan?

    Japan Free Wi-Fi

    Photo by Pixta

    In recent years, locations providing free Wi-Fi have increased not only in train stations and airports but also in cafes throughout Japan.

    However, outside of such establishments, free Wi-Fi is generally not available. It is recommended to prepare a pocket Wi-Fi or SIM card when going to outdoor tourist spots or when using Google Maps in urban areas.

    For information on where free Wi-Fi is available, please refer to the following MATCHA article.

    Q5. Can I buy the Japan Rail Pass and pocket Wi-Fi as a set?

    JR Pass and Wifi

    The Japan Rail Pass, which allows unlimited travel on Japan Railways (JR), is a convenient pass for traveling in Japan.

    In recent years, a plan has been introduced that allows you to purchase or rent the Ninja Wi-Fi pocket Wi-Fi router along with the Japan Rail Pass (nationwide version). You can apply for this set on the official website of the JR Pass.

    However, please note that purchasing or renting the set plan does not necessarily make it cheaper. For example, using the previously mentioned discount, the Ninja Wi-Fi costs 3,080 yen for 5 days, while if you rent it within the set plan, it costs 5,800 yen (with added insurance).

    The Japan Rail Pass can be easily purchased through the activity booking site Klook. Unless you have a specific reason to do so, it is not recommended to purchase the set plan unless all you wish for is convenience.
