Prices tend to decrease with the length of the trip; longer rentals generally get you better rates. Ranking Japan's mobile Wi-Fi options As you can see, there are a lot of Wi-Fi rental options in Japan. To make the choice easier for you, we've compared the different providers (we made a spreadsheet and everything, but we'll spare you the gory details) and present what we think are the top choices below. It's by no means an exhaustive list, but we hope it's helpful. 1. Best-value pocket Wi-Fi router in Japan Our criteria: To work out the travel Wi-Fi plans that have the best value, we looked at pricing for 5 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 Wi-Fi in Japan? At the top of our rankings is the Ninja Wifi Unlimited Plan router. Data and speeds Ninja Wifi’s pocket device 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 (including streaming). The router runs on the SoftBank network, using 4G and 4G LTE. Data is a decent 1GB/day; when used up, speeds may be slowed temporarily. Pricing The base rental rate for a Ninja Wifi Unlimited Plan, with tax, is per day, but cheapo readers get a 20% discount, meaning that a five-day rental will cost you just . (Note: The discount is applied automatically when you order through our special link. It's applied before consumption tax is added.) For travelers who need more high-speed data: There is also a 5GB/day plan, as well as a 10GB/day plan and an Infinite Unlimited plan (which we'll get to in more detail later). With the discount applied, the 5GB/day plan costs per day, working out to for three days or for five, without any add-ons. The 10GB/day plan costs per day, with the discount applied. Pick-up and drop-off You can pick up and drop off your Ninja Wifi device for free at the airport — Narita, Haneda, and other major Japanese airports are covered. Or delivery within Japan costs . Also, you can get medical insurance and translation devices as an add-on, which is neat. You'll find all the 1GB/day, 3GB/day, 5GB/day, 10GB/day, and Infinite Unlimited Wi-Fi rental options on the Ninja Wifi order form. Runner-up: Telecom Square WiFiBOX A relatively new entry to the portable Wi-Fi market is the Telecom Square WiFiBOX. Doubling as a portable power bank, you can get high-speed data on the go while charging your devices. Data and speeds Plans range from a minimalist 500MB plan to 1GB, unlimited (3GB), and truly unlimited plans. We'll get to the Truly Unlimited plan in more detail in a later section. The maximum connection time on the WiFiBOX is 12 hours, and you can connect up to five devices. It comes with Micro USB, USB-C, and Lightning cables to charge your devices, but you'll need a separate USB Type-A charger to charge the WiFiBOX itself.

Best mobile Wi-Fi router for digital nomads and business travelers Our criteria: For this category, we considered a range of criteria including reliable connectivity, data limits, battery life, simultaneous device capacity, pick-up and return options, and pricing transparency. We also considered things like flexible rental options, plan extensions, and availability of optional extras. Winner: Ninja Wifi Once again, taking the top spot is Ninja Wifi.

Best pocket Wi-Fi router in Japan for long-term stays Our criteria: 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 Wi-Fi.

Data and speeds You get 100GB of data, with download speeds of up to 150 Mbps. 200GB and 300GB plans are also available. Mobal Wifi uses all of Japan’s big network providers, which helps with consistently smooth surfing. Pricing /month. The minimum contract period is 3 months, though, so this rental Wi-Fi is best suited to exchange students and people taking longer business trips to Japan.

A cool thing about Mobal is that all of their profits go to charity. Pick-up and delivery Mobal provides free delivery in Japan as well as pick-up from Haneda International Airport. Runner-up #2: Sakura Mobile pocket wifi For stays over 90 days, Sakura Mobile's monthly pocket Wi-Fi plans are also worth a look.

If you're here for less than 90 days, Sakura also offers a Travel Pocket WiFi plan.

With 50GB a month (and options for a lower 20GB or higher 100GB, depending on your needs), you should have enough to work with for moderate usage. Speeds are healthy, with 187.5Mbps being the norm, and at a day for two or more months, it’s not too rough on your wallet either. Read our full guide to long-term mobile Wi-Fi in Japan. 7.

In many cases, an eSIM might offer you faster speeds. Many eSIMs now run on local 5G networks, while most pocket Wi-Fi (except for plans like this one from Ninja WiFI) still run on 4G. eSIMs are also often cheaper these days, averaging around per day on a 7-day plan. However, eSIMs might not be the best option for every traveler. If you're with a large group, most pocket Wi-Fi devices can handle up to five users or more. Not all eSIM plans allow personal hotspots or data sharing, and more than a couple of users will usually significantly affect speeds on tethering. The same goes for device compatibility. While pretty much all modern devices will quickly and easily connect to a portable Wi-Fi router, most laptops and even some modern phones and tablets are not eSIM compatible, especially if they're locked to local carriers back home. Japan rental Wi-Fi FAQs Here, we answer some of the most commonly asked questions about pocket Wi-Fi in Japan. What does Fair Usage Policy (FUP) mean? The fair use policy is a policy implemented by local telecommunications networks in Japan to keep network usage fair. While some unlimited Wi-Fi plans have stated daily data caps of a few gigabytes or so, other unlimited Wi-Fi plans are described as truly unlimited, subject to a fair use policy. This means that, while the company that supplies the device says that there is no daily data cap, available speeds may be temporarily throttled by the local network (like Docomo, AU, or Softbank) if your usage is considered unreasonable. What is considered fair use may differ between providers, but as long as you don't go too crazy, you should be OK. Which pocket Wi-Fi rental is the best in Japan? It depends on 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 overall deals for short-term stays in Japan, in our books. How does pocket Wi-Fi in Japan work? Most rental Wi-Fi routers in Japan run on 4G or 4G LTE, with good coverage across the country (even on Mount Fuji). Should I use pocket Wi-Fi, roaming, travel SIM, or eSIM when I'm in Japan? It really depends on your individual needs. If you're traveling in a group and just want data, it may work out cheaper to share data using a pocket Wi-Fi device. If you're traveling solo and just want data, an eSIM is a good alternative to roaming only if your device is unlocked. If your device is locked, a prepaid Japanese travel SIM is another option for data while abroad. If you want the option of using your existing phone number for voice calls and texts, then roaming might be for you. Is pocket Wi-Fi in Japan still worth it? Yes. You usually get more data and faster connectivity speeds than you would with a SIM card. You can also connect multiple devices, like your phone, smartwatch, laptop, and tablet, to a single rental Wi-Fi router. That said, if you don't see yourself using much data, or if it will all be concentrated on one device, e.g., your phone, a SIM, or eSIM might be the better bet. Is it better to get pocket Wi-Fi 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 Wi-Fi router and a SIM for maximum connectivity, but if you can only choose one and you need lots of data for lots of devices, a pocket Wi-Fi router might better meet your travel needs. Is an eSIM or a Wi-Fi router better for Japan? If you take a quick look at our guide to Japan eSIMs, you’ll notice they start to get expensive as you move into heavy data usage. If you’re planning on bringing a laptop or just using a lot of data while you’re here, a Wi-Fi router will probably be more cost-effective than an eSIM. Do I need Wi-Fi router insurance in Japan? Insurance is optional when you rent a Wi-Fi router in Japan, but be sensible and go for at least a basic plan -- it will set you back maybe - 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! Where can I rent a Wi-Fi router on the day? Ninja WiFi offers same-day collection from their Shinjuku office, so you can order while you’re at the airport and then head into Tokyo to collect. Some other providers, such as Japan Wireless, can arrange same-day pick-up if you call them. Finally, major airports in Japan will have a sales kiosk selling SIM cards and renting Wi-Fi routers. They won’t necessarily be the best deals around, but if you’re in a hurry and need data, head on over. Can I pick up my Wi-Fi router at one place and return it somewhere else? Generally speaking, yes. Most Japanese Wi-Fi rental providers allow you to pick up your router at one place, e.g., Narita Airport, and return it 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 Wi-Fi available in Japan? The short answer? Um, yes -- sort of. While there are an increasing number of free Wi-Fi 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 Wi-Fi while traveling around Tokyo and the rest of the country -- unless you're cool with an enforced digital detox.

Cybersecurity is a valid concern in this day and age, but pocket Wi-Fi is generally secure, as your connection is private -- between your pocket router and the device you are using it with, e.g., your cellphone or laptop. Note: Public Wi-Fi is neither private nor secure. You can use a VPN to keep your browsing safe. Do the pocket Wi-Fi companies ship overseas? If you're hoping to get delivery of a pocket Wi-Fi 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, or download an eSIM before your flight. How long does the battery last on a pocket Wi-Fi device? Each provider 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 Maps, your pocket Wi-Fi should easily last all day. A lot of Japan Wi-Fi rental companies include a mobile battery pack with your router, too.

Video guide to pocket Wi-Fi for travelers to Japan While we do our best to ensure the information here is correct, it is subject to change. Note that exceeding data limits could, in addition to seeing speeds slow, result in a temporary suspension of service. Check all prices and T&Cs carefully with the provider before ordering your pocket Wi-Fi router. Post regularly updated. Last update: June 2025 by Patrick Balfe.
