Pocket Wi-Fi in Japan: How to choose More than 30 companies provide Wi-Fi router rental in Japan, with variations in data allowances, speeds, coverage, customer service, and rental periods. Most of Japan's pocket Wi-Fi routers use 4G or 4G LTE and can be rented for the exact number of days you'll need one, e.g., 3, 7, 14, or 30+ days. Our advice is to get the fastest speed possible and opt for lots of, or unlimited, data. Just note that many plans have daily data caps, after which speeds are temporarily reduced. And be sure to choose a company that runs on one of Japan's three major networks—Sotbank, AU, or Docomo. Overview of pocket Wi-Fi for tourists and long-term visitors to Japan To make the choice easier for you, we've compared different Japan Wi-Fi rental 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. Pickup and dropoff You can pick up and drop off your 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 #1: 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. Pricing The 1GB plan goes for a reasonable /day, the Unlimited (3GB per day plan) is /day, and the Truly Unlimited offering is a very nice /day. Pickup and dropoff You can pick up and return the device at various airports and train stations around Japan. Runner-up #2: CD Japan Another contender, thanks to its speeds, is CD Japan. Data and speeds CD Japan offers a CloudAir pocket Wi-Fi 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.

Best mobile Wi-Fi router for heavy data usage Our criteria: In this category, we considered the companies that offer the most bytes for your buck. Winner: Telecom Square WiFiBOX If you're planning to burn through a ton of data (YouTube and the like), the Telecom Square WiFiBOX Truly Unlimited plan inches out the competition in terms of cost. Data and speeds The company website markets solid speeds of up to 150Mbps. A lot of Wi-Fi rental plans are advertised as "unlimited," but in many cases, that means that while you'll still have access to the internet, your speeds will be slowed to a crawl after reaching a certain daily data limit. This means a truly unlimited option such as this is a good find for big data users. Pricing The Truly Unlimited option will set you back per day, which puts it just above the rest in terms of affordability. Pickup and dropoff Various airports and train stations around Japan. Runner-up #1: Ninja Wifi Infinite Unlimited Ninja Wifi also has a truly unlimited option for big data users. Data and speeds The Infinite Unlimited option from Ninja Wifi also has no daily data cap, and you can expect the same decent 187Mbps on the Softbank network as the other Ninja Wifi products mentioned above. The Ninja Wifi website promises no limit on daily data usage, except in rare cases where excessive data usage within a certain period may result in speed restrictions during peak times. Pricing With our discount, the price per day for this plan is . Pickup and dropoff Free pickup at most major airports around the country or domestic delivery for . Runner-up #2: Japan Wireless Business Wifi Another good option is the "Business Wifi" plan from Japan Wireless. Data and speeds The plan gives you (theoretically) unlimited data on the SoftBank network, with download speeds of up to 120Mbps -- fairly high. Pricing Rates start at for your first day, adding around for each subsequent day, rounding out at for the month. If you really need your speed, their Premium Wifi plan comes with the same perks, longer battery life and speeds of up to 187.5Mbps -- for just a small increase in price. For example, 14 days of Business wifi costs , whereas Premium wifi costs . Delivery Free delivery (except for same-day). 3. 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. Winner: Wi-FiRental.com If you're going to be in Japan for more than a month, the K4 Unlimited plan from Wi-FiRental.com is worth considering. Data and speeds The package provides 3GB of data per day at approximate maximum download speeds of 187.5 Mbps. The minimum rental period is one month, and there are no complicated contracts (or hidden fees) to worry about. So, if you need a router for just 2-3 months, it's easy. Pricing /month (inclusive of tax). Delivery costs . 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 (and eSIM) game, Mobal also has a long-term Wi-Fi offering. 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. One thing to note is that you need to pay for the Wi-Fi router upfront ( new or pre-owned), but it's yours to keep once the contract is up. A cool thing about Mobal is that all of their profits go to charity. Delivery Free delivery. Runner-up #2: Sakura Mobile pocket wifi For stays over 90 days, Sakura Mobile's pocket Wi-Fi is also worth a look. They offer a rolling month-to-month contract with various plans, including a 100GB ()/month deal. There is a one-off activation fee on all of their plans. Worth considering: eConnect Japan Premium Plan For those spending a few months in Japan, the eConnect Japan Premium Plan offers a balance of data and affordability that makes it a worthy contender. 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. 4. Best mobile Wi-Fi router for very short trips to Japan Our criteria: For this category, we looked at plans that are good value for stays of just 2-3 days. Winner: At per day for 500MB or for 1GB, it's hard to go past Telecom Square for short trips and small data usage. While their unlimited plans are a little pricier, they're still very affordable. Runner-up: Ninja Wifi If you're making a super short trip, the Ninja Wifi router is also a great choice—you're looking at for 3 days, thanks to our specially negotiated cheapo discount. Renting a pocket Wi-Fi router in Japan: How it works It's very easy to rent a pocket Wi-Fi router for your trip to Japan. All you need to do is fill out a quick online application (all providers here have English booking pages), 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 and . In most cases, booking your Japan Wi-Fi two to three days in advance is sufficient. Once you've got the pocket Wi-Fi router, 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. Before you leave Japan, either return the router in the prepaid envelope provided (just pop it into a postbox) or drop it off at the airport before you check in -- different providers have different requests. Japan rental Wi-Fi FAQs Here, we answer 13 of the most commonly asked questions about pocket Wi-Fi in Japan. 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 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 pickup 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. Read more about connecting to the internet in Japan. Is portable Wi-Fi in Japan secure? Worried that someone may hack into your Japan Wi-Fi egg and pinch your personal data? 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. If you happen to be planning a UK trip too, or you just want to weep at how pricey pocket Wi-Fi in Japan is compared to the UK, check out our London Cheapo Guide to the best UK mobile broadband providers. 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: May 2025 by Patrick Balfe.
