Pocket WiFi: Portable Routers for Japan Travel

Renting a pocket Wi-Fi is the best way to stay connected in Japan if you have multiple devices—like a phone and laptop—or are traveling with family and friends who can share the connection.

If you're traveling solo and only need your phone for basic tasks—like maps, messaging, and checking social media—an eSIM is often the better choice.

Pocket Wi-Fi rentals in Japan cost between 400 yen and 1,200 yen per day, depending on the rental length, data limit, and network type. Keep in mind that while some providers include the device in the price, others charge a separate rental fee on top of the connection rate.

Best Pocket WiFi in Japan: Quick Comparison

Our Top 3 Pocket WiFi Recommendations: NINJA WiFi, Japan Wireless, Sakura Mobile

NINJA WiFi, from Global Wi‑Fi (Vision Inc.), is highly rated for its wide range of plans. With flexible options for light browsing or video streaming, you can choose the plan that fits your needs and keep costs low — making NINJA WiFi the best value-for-money choice.

Japan Wireless previously offered Business and Premium plans but now provides a single Unlimited Wi‑Fi option. Its main advantage is truly unlimited data with consistent speeds regardless of usage, making it one of the best choices for heavy data users.

Sakura Mobile’s pocket Wi‑Fi has a single, easy-to-book plan. Its biggest advantage is highly rated English support, which is helpful for first‑time users in Japan.

At MATCHA, we tested and compared these three major pocket Wi‑Fi services. Below are detailed features to help you choose the best one for your needs.

1. NINJA WiFi: Several Plans Available + 80% Autumn Discount!

Picture courtesy of NINJA WiFi

NINJA WiFi is our recommended service as the best pocket WiFi for travelers to Japan, because it offers the best balance of quality and price.

The 4G/5G connection remains reliable even when multiple devices are connected, making it ideal for family, group, or business travel. Additionally, you can choose from a variety of plans to suit your specific connectivity needs.

NINJA WiFi is provided by Vision, a well-established internet service company known for its Global WIFI brand.

NINJA WiFi Cost and Plans

4G Plans	Cost	MATCHA Discount	Price after Discount
Unlimited 1GB/day	440 yen/day	80%	88 yen/day
Unlimited 3GB/day	770 yen/day	80%	154 yen/day
Unlimited 5GB/day	1,100 yen/day	80%	220 yen/day
Unlimited 10GB/day	1,320 yen/day	80%	264 yen/day
Infinite Unlimited	1,980 yen/day	80%	396 yen/day

5G Plan	Cost	MATCHA Discount	Price after Discount
Unlimited Plan	2,200 yen/day	80%	440 yen/day

As summarized above, with NINJA WiFi, you can choose from 4G and 5G plans.

Until December 31, 2026, all the Unlimited plans are available at a special 80% discount when booked through MATCHA.

No coupon code is required—the discount is applied automatically when booking via this link.

Data Limits

The NINJA WiFi plans are unlimited within the data capacity of your plan.

How it works:
- If you book the Unlimited 3GB/day plan, you'll be able to use 3GB of data per day without any speed restrictions. If you exceed this limit, your speed will slow down, but you'll still be able to access the internet.

Our tip:
- If you're traveling in a group and plan to connect more than three devices to the router, we recommend booking the Unlimited 10GB/day plan or the Infinite Unlimited plan (both available at a 80% discount this autumn) to ensure all group members have sufficient connectivity.

Speed

Both the 4G and 5G plans of NINJA WiFi offer a standard speed of 187 Mbps. Please note that speeds will be reduced to 128 kbps if you exceed your daily data limit, resulting in slower internet access.

*Many other companies advertise "unlimited" plans but actually impose speed restrictions after users consume 2 to 3 GB per day. In contrast, NINJA WiFi clearly outlines its high-speed data limits, enabling users to utilize the service with confidence.

Network Coverage

NINJA WiFi's 4G plans use the SoftBank network, ensuring reliable connectivity across all populated areas of Japan.

The 5G plan uses the docomo network, which provides access even in remote areas such as islands and mountain regions. If you plan to travel to remote areas of Japan, we recommend choosing the NINJA WiFi 5G Unlimited plan.

Number of Devices

A NINJA WiFi portable router can support up to 15 devices simultaneously. In our tests, we connected up to 8 devices without experiencing any connectivity issues.

Pick-up and Return

NINJA WiFi is notable for offering the most pickup locations. You can collect your device at most major international airports in Japan, or at the NINJA WiFi office in Tokyo.

They have recently introduced a smart-pickup system that uses coin lockers, an industry first. Check the complete pick-up location list here: https://ninjawifi.com/en/receive/smartpickup

Customer Service

NINJA WiFi provides 24-hour customer support in English. You can contact them for assistance with connectivity issues or questions about the pick-up and return of the router.

User Review

We conducted real-use tests of NINJA WiFi in April 2025. During the tests, we connected five computers for work and three smartphones, and we were surprised at how smooth the communication was.

With dedicated counters at the airport, NINJA WiFi is easy to pick up and return. Plus, the discount coupons make it so convenient! This is a service we can confidently recommend.

You can also book the NINJA WiFi with Welcome Suica (prepaid IC card for Japan public transportation) option, pick them up together at the airport counters, and take the train to start your journey right away. This means you won't need to wait in line to buy the Suica card.

2. Japan Wireless: Just ONE Plan with Truly Unlimited Data

Japan Wireless simplifies the pocket WiFi rental process by offering just one unlimited data plan without speed limitations.

Japan Wireless Pocket Wi-Fi: More Cost-Effective for Longer Rental Periods

With Japan Wireless pocket Wi‑Fi, daily rates drop the longer you rent:

- Japan Wireless Unlimited Wi‑Fi: 4,064 yen for 1 day or 20,860 yen for 30 days (≈ 695 yen/day)

Moreover, you can get the Japan Wireless Unlimited WiFi at a 20% discount from MATCHA.

Data Limits

Japan Wireless offers unlimited data capacity.

Speed

- Japan Wireless Unlimited Wi-Fi: 187Mbps

Network Coverage

Japan Wireless uses the 4G network, ensuring connectivity in all populated areas of Japan.

Number of Devices

- You can connect up to 8 devices to the Japan Wireless pocket WiFi router.

Pick-up and Return

The Japan Wireless pocket WiFi can be picked up at major airports in Japan, as well as at post offices and their headquarters in Tokyo.

To return the router, you can simply drop it in a postbox in Japan. The provider covers the return postage, making the process very convenient.

Customer Service

Japan Wireless offers customer support in English, seven days a week.

User Review

Japan Wireless's strength lies in the fact that there are no speed restrictions regardless of data usage. This makes it a recommended service for those who prioritize an unrestricted data experience, even if it comes at a slightly higher cost.

Japan Wireless is a highly recommended service for those who want to use a high-capacity plan. Similar to the aforementioned NINJA WiFi, the communication quality is very good, allowing for smooth operation even when connecting several computers.

3. Sakura Mobile: Excellent Service Support in English

Photo by Sakura Mobile

Founded in 2014, Sakura Mobile has garnered high praise for its internet services aimed particularly at English-speaking tourists and students in Japan.

They offer two types of pocket WiFi: short-term rental for travelers and long-term subscription plans for residents. Below, we focus on the features of their pocket WiFi for travelers.

Sakura Mobile Pocket WiFi: Cost and Plans

Compared to NINJA WiFi, which offers a variety of plans to choose from, Sakura Mobile's pocket WiFi offers only one option.

Prices vary depending on the season and rental duration. For example, as of October 2026, the base rate was ¥1,307 per day, with automatic length-of-stay discounts applied (e.g., 30% off for 9 days or 45% off for 16 days). *The cost does not include the pocket WiFi insurance and spare battery rental fee.

Data Limits and Speed

While the service generally offers unlimited data, there may be speed reductions if one violates the Fair Usage Policy (FUP).

Network Coverage

The Sakura Mobile pocket WiFi uses a 4G network, offering connectivity in all populated areas in Japan.

Number of Devices

The pocket WiFi is shareable among several devices.

Pick-up and Return

The Sakura Mobile pocket WiFi can be picked up at major airports in Japan (Tokyo, Osaka, Nagoya, Fukuoka, Hokkaido), but also at their Tokyo office and at hotels.

Customer Service

The biggest advantage of Sakura Mobile’s pocket Wi-Fi is its dedicated English customer service and troubleshooting support.

Known for quick response times, the company helps users decide whether a SIM card or pocket Wi-Fi best fits their travel needs. Travelers—especially first-time visitors to Japan—consistently praise Sakura Mobile as a helpful, reassuring partner.

User Review

What surprised us during actual use was the excellent battery life. Even after connecting five computers and working for an hour, the battery had only decreased by 2%.

However, the communication speed was significantly slower than that of NINJA WiFi.

We recommend Sakura Mobile's pocket WiFi for travelers who do not plan to use a lot of data during their trip and who prefer having reliable support in English for added peace of mind.

How We Tested Japan Pocket WiFi Services

In addition to our office testing in Tokyo—featured above in our reviews of NINJA Wi-Fi, Japan Wireless, and Sakura Mobile—we put NINJA Wi-Fi to the test during a family trip through Kyoto, Nara, and Osaka.

MATCHA's English editor tested the device when her 6-member family—two kids, their parents, and a pair of grandparents—visited Japan for the first time. We booked the Unlimited 5GB/Day plan for 10 days.

During the Shinkansen ride from Tokyo to Kyoto, the kids were playing online games, their parents were uploading videos and photos on social media, the grandparents were exchanging messages with friends back home, and our editor was doing the online check-in for their accommodation.

We had eight devices connected and in active use, and we encountered no connectivity issues. The battery held up well until we reached our destination.

Our only regret was not choosing the Unlimited 10GB/Day plan—since with seven people using the connection simultaneously, 5GB per day wasn’t always enough.

How Much Does Pocket WiFi Cost in Japan?

Pocket Wi-Fi rentals in Japan cost between 400 yen (2.50 USD) and 1,500 yen (9.50 USD) per day, depending on rental duration, data limits, and network type.

Comparing pocket Wi-Fi providers in Japan can be tricky because pricing models vary significantly.

For example, Sakura Mobile appears more expensive upfront, but automatic length-of-stay discounts make it very cost-effective for longer rentals.

Conversely, services like Wi-Fi Rental Store or Purupuru Wi-Fi charge separate delivery fees that increase the total cost. Furthermore, while most providers offer all-inclusive rates, some bill the hardware rental separately from the data plan.

Although NINJA WiFi and Japan Wireless may look pricey at first glance, they frequently run heavy promotions—up to 80% off for NINJA WiFi. Given their strong reliability and transparent pricing, we recommend choosing between these two based on your specific connectivity needs.

Best Pocket WiFi by Travel Style

Best Choice for Family Travel: NINJA WiFi's Unlimited 10GB/Day

If you travel to Japan with your family or as a group, you'll want a shared router that offers a reliable connection and long-lasting battery life.

NINJA WiFi offers the best value for unlimited data plans with high-speed connectivity, especially when you take advantage of the 80% discount.

The router can support multiple devices at the same time, making it suitable for various activities such as video streaming, online gaming, web browsing, using Google Maps, social media, business tasks, and more. Additionally, it boasts a robust battery life of up to 12 hours.

NINJA WiFi also offers the option to book two routers together at a discounted price. This is a great choice for groups larger than five people.

2nd Best Choice: Japan Wireless Unlimited WiFi

Japan Wireless Unlimited Wi‑Fi offers a single plan, making it very easy to book. The device is simple to set up and maintains a consistent speed regardless of how many devices are connected.

It has about a 10‑hour battery life and includes a free power bank for extended use.

Best Choice for Business Travel: NINJA WiFi's Unlimited 10GB/Day

As a digital nomad or business traveler in Japan, it's essential to have full connectivity at all times, wherever you are in the country. High speed and long battery life are the most important criteria for reliable, uninterrupted service.

With its Unlimited Data plans, NINJA WiFi meets the needs of any business traveler, whether you're using multiple devices simultaneously or conducting consecutive online meetings.

The Unlimited 5GB/day or Unlimited 10GB/day plans should be perfect for your requirements.

The battery lasts for about 12 hours. Be sure to also enjoy some downtime to take in the stunning sights and experiences that Japan has to offer.

2nd Best Choice: Japan Wireless Unlimited WiFi

The pocket WiFi offered by Japan Wireless offers unlimited data and up to 10 hours of battery life. It can support up to 8 devices simultaneously.

The only reason it ranks below NINJA WiFi is its higher price. If you prefer this service, book it from this link to get a 20% discount.

Best Choice for Heavy Users:
NINJA WiFi's 4G Infinite Unlimited or the 5G Unlimited

Travelers who document their trips through live streams and videos or need to stay online throughout the day should look for a pocket WiFi that offers truly unlimited data, high-speed connectivity, and long-lasting battery life.

NINJA WiFi's 4G Infinite Unlimited Data plan guarantees no speed restrictions, regardless of your usage. Its 4G network coverage ensures availability in all populated regions of Japan.

If you're visiting remote islands or mountainous areas, consider the 5G Unlimited plan—the only portable WiFi that truly works in remote and rural locations in Japan.

The battery lasts around 12 hours. Both plans can be booked at a discount through MATCHA, making them highly cost-effective.

2nd Best Choice: Japan Wireless Unlimited WiFi

Japan Wireless Unlimited Wi-Fi is also a great option, offering coverage across all of Japan's populated areas. The battery lasts approximately 20 hours.

While it may not be as budget-friendly as NINJA WiFi, it is still available at a 20% discount.

Best Budget Pocket WiFi

With the 80% discount, the NINJA WiFi 4G Unlimited plan is the most cost-effective choice at just 396 yen/day.

For light data users, the eConnect Japan Economy Plan offers a solid alternative at 432 yen/day with a 20 GB monthly cap.

Best Pocket WiFi for Long Stays

WiFi-RENTAL.COM and CDJapan Rental offer long-term plans starting at 6,600 yen/month.

Other Pocket WiFi Rental Companies in Japan

In addition to our top recommendations listed above, there are other pocket WiFi services in Japan that offer additional advantages, such as customer support in languages other than English.

Wifi Rental Store: Plans Available for 390 Yen/Day

Photo by Wifi Rental Store

Wifi Rental Store has been providing Wi-Fi rental services for Japanese and visiting tourists since 2013.

For example, if you choose the one-month 50 GB plan, it will cost 490 yen per day, which is slightly more expensive compared to Japan Wi-Fi rental. On the other hand, there is also a plan where you can use 20 GB per month for 390 yen per day. If you require less data, this plan may be a better option for you.

Please note that Wifi Rental Store primarily operates through the postal service for both receiving and returning WiFi routers, with a round-trip cost of 1,100 yen.

For an extra charge, you have the option to pick up the device at the airport or their store in Akihabara for 550 yen. Returning the device to the store will refund the return postage of 550 yen upon handing over the return envelope.

eConnect Japan: 4 Plans for Every Connectivity Needs

eConnect Japan offers 20 GB, 50 GB, 100 GB, and unlimited data plans running on the SoftBank network at speeds up to 187.5 Mbps.

Keep in mind that while their connection rates may appear low, eConnect charges for hardware rental separately. This hardware fee raises the total daily cost, making it more expensive than a discounted NINJA WiFi plan.

PUPURU WiFi: Easy to Carry! Pocket WiFi Stick

PUPURU offers portable Wi-Fi with strong coverage, particularly in major cities like Tokyo, Osaka, and Kyoto.

However, PUPURU's rates are higher than many competitors, and rentals incur a 1,800 yen shipping fee.

Its main highlight is an AI chatbot available for pre-rental inquiries. While most Japanese Wi-Fi providers offer English customer support, PUPURU's chatbot provides instant answers if you need quick assistance before booking.

AnyFone Pocket WiFi: 5G Unlimited with Airport Pickup

AnyFone Pocket Wi-Fi offers 5G Unlimited plans starting at 860 yen per day. Running on KDDI’s major nationwide network, the sleek unit provides fast, stable 5G connectivity for up to 10 devices at once—making it a great choice for families and groups traveling together.

You can reserve your device online ahead of time for easy airport pickup, or rent one directly at the airport store upon arrival without a prior booking.

Global Advanced Communications: Customer Support in French

Global Advanced Communications offers two main options: a standard Unlimited Plan with speeds up to 350 Mbps (762 yen/day for 15 days) and a 5G Unlimited Plan featuring high-speed 5G access (1,173 yen/day for 15 days).

Notably, the company provides customer support in French as well as English.

Pocket Wi-Fi Services for Long Trips (One Month or Longer)

If you're visiting Japan for a long-term stay for study or work, we recommend using one of the following services.

Wi-Fi RENTAL.COM: Several Pick-Up Counter Options

Photo courtesy of Wi-Fi Rental.com

Wi-Fi RENTAL.COM is a service boasting over 1.5 million users.

They offer three plans: one with unlimited data on the SoftBank network with a daily limit of 5GB at 6,600 yen per month, another with a monthly limit of 5GB at 3,190 yen, and a plan on the WiMAX network with a 10GB limit over 3 days at 6,930 yen per month.

The daily 5GB plan is especially popular as it provides around 150GB per month, making it very convenient for studying, working, or watching videos during holidays in Japan.

One significant advantage is the wide availability of pickup counters. They cover various locations, including Narita, Haneda, Kansai International Airport, Osaka Itami Airport, Chubu Centrair International Airport, Fukuoka Airport, New Chitose Airport, Naha Airport, and Komatsu Airport, ensuring easy access to the internet upon arrival in Japan.

Moreover, if you need to have the device delivered to your accommodation in Japan or returned as you depart the country, using this MATCHA coupon can waive the delivery fee (totaling 1,100 yen for pickup and return).

mobal: Pocket WiFi Stick Compatible with All Major Networks

Photo courtesy of mobal

mobal is operated by Mobell Communications Limited, a UK telecommunications company established in 1989.

Its main advantage is its ultra-portable USB Wi-Fi stick, which is much easier to carry than a traditional pocket router.

By plugging the stick directly into your device, you get high-speed internet that automatically connects to the strongest signal among Japan's four major networks: SoftBank, NTT Docomo, Rakuten, and au.

Note that the Mobal Wi-Fi stick is sold outright rather than rented, costing 6,980 yen. Users can then choose between three monthly data tiers: 100 GB for 4,980 yen, 200 GB for 5,980 yen, or 300 GB for 6,980 yen.

A notable aspect of mobal is that you can get a 10% discount on the pocket Wi-Fi rental when you subscribe to both the SIM card/eSIM and the pocket Wi-Fi as a set. This is convenient for those who plan to stay in Japan for a long period as they will have both a SIM card for their smartphone and a high-capacity pocket Wi-Fi for devices like laptops. Please check mobal's official website for more details.

Furthermore, Mobell Communications Limited is notable for its active involvement in charity, such as directing a portion of its profits to support impoverished communities in Africa.

CD Japan Rental: Good Choice for Heavy Internet Users

Photo by CD Japan Rental

CD Japan Rental provides a pocket Wi-Fi service that is convenient for stays of one month or longer.

A popular option is the 30-day plan offering 100 GB for 7,500 yen. Additionally, there are plans like 150 GB for one month at 6,900 yen and an unlimited data 30-day plan for 11,180 yen.

CD Japan Rental stands out for offering the ability to use large amounts of data at relatively affordable prices for rentals of several months. For instance, a 3-month unlimited data plan costs 7,900 yen per month (with a minimum usage period of 3 months).

For short-term rentals, you can rent for 5 days starting at 3,560 yen.

How to Rent a Pocket Wi-Fi Router in Japan

Photo by Pixta

The process for using pocket Wi-Fi is as follows:

1) Make a reservation online before arriving in Japan
2) Pick up the router at the airport or hotel after arrival
3) Return it before leaving Japan (via mail or at the airport counter)

In case of damage or loss, there may be a penalty fee (around 40,000 yen), so handle the device with care. Selecting insurance as an optional extra can provide peace of mind in such situations.

Airport Rental vs. Pre-ordering

All major airports in Japan, such as Narita and Haneda, have rental counters where you can rent Pocket Wi-Fi. You can pick up and rent devices on the same day at these airports.

However, when applying on the day at the airport, there are risks and disadvantages such as:

1) the possibility of no inventory available for rental and
2) the potential for higher fees compared to pre-ordering (the price difference can be around 20%).

Therefore, MATCHA recommends pre-ordering for a smoother experience.

Pocket WiFi vs eSIM: Which Is Better?

This video compares Pocket WiFi, SIM cards, and eSIMs. If you're unsure whether to choose Pocket WiFi or eSIM, please watch this first.

Choose an eSIM if: You are traveling solo, only need light data (for maps and messaging), and prefer not to carry extra hardware.

Choose Pocket Wi-Fi if: You need high data allowances, are traveling with family or a group, or want a consistently strong connection across multiple devices.

Key Advantages of Pocket Wi-Fi

- Better Value for High Data: Offers larger data allowances at lower per-gigabyte rates.

- Simpler Setup: No complex phone activation or profile installation—just turn it on and connect using the password (avoiding eSIM activation errors).

- Multi-Device Sharing: Easily connects laptops, tablets, and phones for several people simultaneously.

To those who prefer using an eSIM for connectivity, we recommend the MATCHA Japan eSIM. You can choose from various plans, including plans with unlimited data, and get your eSIM at a 40% discount.
