If you’re wondering how best to stay connected while you’re traveling around Japan, a pocket wifi router might be the solution. Often more practical than tourist SIM cards, especially useful if you are traveling in a group or have multiple devices (e.g. two phones, a tablet, laptop and so on), and super simple to collect and drop off, these mobile wifi routers are a clever choice. Here, we show you how to rent a portable wifi router in Japan, as well as a few of the best options in terms of value, data usage and length of stay.
Renting a pocket wifi router in Japan: How it works
It’s very easy to rent a pocket wifi router for your trip to Japan. All you need to do is fill out an online application (most providers have English web pages for tourists), and the portable router will be ready for collection at the airport when you arrive, or delivered to your accommodation shortly after (or even before) you get there. Both options are often free, but if not, you’re looking at a small levy of between ¥500 and ¥1,100. In most cases, booking two to three days in advance is sufficient.
Once you’ve got the pocket wifi router, sometimes called a wifi egg, in your cheapo paws, you just switch it on, connect to it from your devices (you’ll have been given the password) and boom—you have the interwebs at your disposal. Just before you leave Japan, you either return the router in the prepaid envelope provided (just pop it into a postbox), or drop it off at the airport—different providers have different requests.
Pocket wifi in Japan: How to choose
There are more than 30 companies that provide wifi router rental in Japan, with variations in data allowances, connectivity speeds, coverage, customer service and rental periods. Most of Japan’s pocket wifi routers use 4G or 4G LTE and can be rented for the number of days you’ll need one for, e.g. 3, 7, 14 or 30+ days. You can often combine the router with another device, e.g. a power bank—which is handy if you’re doing a lot of sightseeing.
Our general advice is to get the fastest speed possible and opt for lots of, or unlimited, data (note that many plans have daily data caps after which speeds are temporarily reduced). After all, you’re going to be uploading loads of pics and footage of your fabulous adventures in Japanland to make your friends jealous—and you don’t want to get throttled in these noble endeavors. We may be cheapskates, but we believe in decent internet.
To make the choice easier for you, we’ve compared the different Japan wifi rental providers (we made a spreadsheet and everything, but we’ll spare you the gory details) and present what we reckon are the top choices below. It’s by no means an exhaustive list, but we hope it’s helpful.
1. Best-value pocket wifi router in Japan
To work out the router plans that have the best value, we looked at pricing for five days, plus speed and data allowances, as well as English-language customer support. We used similar criteria across the categories below.
Winner: Ninja Wifi
So, what’s the best pocket wifi in Japan? At the top of our rankings is the Ninja Wifi Unlimited Plan router, a pocket device that provides download speeds of up to 187.5 Mbps and upload speeds of up to 37.5 Mbps—more than fast enough for doing most things. The router runs on the SoftBank network, using 4G and 4G LTE technology. Data is a decent 3GB/day; when that’s used up, speeds may be slowed temporarily.
The base rental rate for a Ninja Wifi Unlimited Plan, with tax, is ¥770 per day, but cheapo readers get a 20% discount, meaning that a five-day rental will cost you just ¥3,080. (Note: The discount is applied automatically when you order through our special link.) You can pick up and drop off your device for free at the airport—both Narita, Haneda and other major Japanese airports are covered. Also, you can get medical insurance and translation devices as an add-on, which is neat.
For travelers who need more high-speed data: There is also a 5GB/day plan, as well as a 10GB/day plan. With the discount applied, the 5GB/day plan costs ¥880 per day, working out to ¥2,640 for three days or ¥4,400 for five, without any add-ons. The 10GB/day plan costs ¥1,056 per day, with the discount applied. You’ll find the 5GB/day and 10GB/day wifi rental options on the Ninja Wifi order form.
Runner-up: CD Japan
Another contender—thanks to its speeds—is CD Japan, where you can get, among other options, a CloudAir pocket wifi router that gives you download speeds of up to 150Mbps and upload speeds of up to 50Mbps. Data is unlimited, but should you use more than 150GB in a month, speeds will be reduced for a period. Rates start at ¥3,650 for five days (the minimum rental period), going up to ¥11,100 for 30. Thereafter, rates drop. Note that insurance, as with most other rental wifi routers in Japan, is extra, and there is a delivery fee of ¥540.
2. Best mobile wifi router for heavy data usage
In this category, we looked at which companies offer the most gigabytes for your buck.
Winner: Japan Wireless pocket wifi
If you’re planning to burn through a ton of data, you might consider a rental wifi router from Japan Wireless. Their Business Wifi plan gives you download speeds of up to 95Mbps and theoretically unlimited data on the SoftBank network. Rates start at ¥2,728 for two days and climb to ¥14,047 for a month-long rental. There is also a Premium Wifi option that has download speeds of up to 187 Mbps, but is a few hundred yen more. Delivery is ¥550 and you get an extra mobile battery for free.
Runner-up: Ninja Wifi and others
Another good option is actually the previously mentioned Ninja Wifi. Although their website states that there is a fair-usage policy for high data use, it’s not necessarily always enforced in practice.
The aforementioned CD Japan, as well as rental wifi from a company called Global Advanced Communications (whose fair usage policy is 5GB/day), are also potential picks for “unlimited” pocket wifi in Japan for travel purposes.
3. Best pocket wifi router in Japan for long-term stays
Here, we have considered the needs of travelers coming to Japan for upwards of 30 days. If you’re planning to be here for a month or more, these are some of your best options when it comes to portable wifi.
If you’re going to be in Japan for more than a month, the SoftBank Unlimited T06 Plan from Wi-FiRental.com is worth considering. Priced at ¥6,600/month (inclusive of tax), the package provides 5GB of data per day (or 150GB/month) at approximate maximum download speeds of 187.5Mbps. The minimum rental period is one month, and there are no complicated contracts to worry about. So if you need a router for just 2-3 months, it’s easy.
Special discount: Use the coupon code cheapo for free delivery both ways.
Runner-up #1: Mobal Wifi
A hugely popular name in the Japan SIM game, Mobal also have a long-term wifi offering. For ¥4,980/month, you get 100GB of data, with maximum download speeds of 150Mbps. The minimum contract period is three months, so this is best suited to exchange students, longer business trips and the like.
One thing to note is that you need to pay for the wifi router upfront (¥6,980), but it’s yours to keep once the contract is up. A cool thing about Mobal is that the majority of their profits go to charity.
Runner-up #2: Sakura Mobile pocket wifi
For stays over 90 days, Sakura Mobile pocket wifi is also worth a look. They offer a rolling month-to-month contract with various plans, including a 30GB (¥5,478)/month deal. There is a once-off ¥5,500 activation fee on all of their plans.
Worth considering: Kyushu Wifi Rental
The SoftBank Pocket WiFi 501HW from Kyushu Wifi Rental (despite the name, they operate countrywide) is another viable option, giving you 100GB of data on the SoftBank LTE network at download speeds of up to 187.5Mbps and uploads of up to 37.5Mbps. Basic fees are capped at ¥9,570 for a month. Round-trip postage costs ¥1,100. If you rent for 4-6 months, rates drop. The website, however, does require some Japanese-language skills.
4. Best mobile wifi router for very short trips to Japan
For this category, we looked at plans that are good value for stays of just 2-3 days.
Winner: Ninja Wifi
If you’re making a super short trip, the Ninja Wifi router is a great choice—you’re looking at ¥1,848 for three days, thanks to our specially negotiated cheapo discount.
Runner-up: Kyushu Wifi Rental
Getting one of the Kyushu Wifi Rental routers might be another economical option. Their SoftBank Pocket WiFi 501HW costs about ¥528 per day (but don’t forget to add in the postage fees of ¥1,100). There are also slower and capped packages, which could work out a bit cheaper, so check them out.

Japan rental wifi FAQs
Which pocket wifi rental is the best in Japan?
It depends what you are looking for in terms of data, speed and rental period, but the Ninja Wifi Unlimited Plan router is one of the best deals for short-term stays in Japan, in our books.
How does pocket wifi in Japan work?
Most rental wifi routers in Japan run on 4G or 4G LTE, with good coverage across the country (even on Mount Fuji).
Is pocket wifi in Japan worth it?
Yes. You get more data and faster connectivity speeds than you would with a SIM card, generally speaking. You can also connect multiple devices, like your phone, smartwatch, laptop and tablet, to a single rental wifi router.
Is it better to get pocket wifi or a SIM card in Japan?
It depends on your budget and needs (e.g. will you need a Japanese phone number for your stay?). We usually recommend both a wifi router and SIM, for maximum connectivity, but if you can only choose one, and you need lots of data for lots of devices, a pocket wifi router might better meet your travel needs.
Do I need wifi router insurance in Japan?
Insurance is optional when you rent a wifi router in Japan, but be sensible and go for at least a basic plan—it will set you back maybe ¥500–¥3,000 in total, but will save you potentially zillions in stress reduction. The last thing you want is a router return nightmare just before you board your flight!
Can I pick up my wifi router at one place and return it somewhere else?
Generally speaking, yes. Most Japan wifi rental providers allow pick-up of your router at one place, e.g. Narita Airport, and return at another place, e.g. Haneda Airport. In most cases, you’ll actually be posting the router back, so all you need to do is put it in the mailbox.
Is free wifi available in Japan?
The short answer? Um, yes—sort of. While there are an increasing number of free wifi hotspots in Japan, there are still (we think, anyway) nowhere near as many as there should be, and sometimes connecting can be tricky. It’s not advisable to rely exclusively on free wifi while traveling around Tokyo and the rest of the country—unless you’re cool with an enforced digital detox. Read more about connecting to the internet in Japan.
Is portable wifi in Japan secure?
Worried that someone may hack into your Japan wifi egg and pinch your personal data? Cyber security is a valid concern in this day and age, but pocket wifi is generally secure, as your connection is private—between your pocket router and the device you are using it with, e.g. your cell phone or laptop.
Note: Public wifi is neither private nor secure. You can use a VPN to keep your browsing safe.
Do the pocket wifi companies ship overseas?
If you’re hoping to get delivery of a pocket wifi device before you leave for Japan, the answer is “no”. If you want to take a device with you on your flight to Japan, you’ll need to find a service that provides this in your home country. Alternatively, you could order a Japan travel SIM from Mobal, which provides delivery around the globe.
How long does the battery last on a pocket wifi device?
Each of the providers uses different devices, so the exact battery usage time varies. However, for most devices, the quoted continuous usage time for a fully-charged device is 9 to 11 hours. If you’re out and about and just browsing Google Maps, your pocket wifi should easily last all day.
