Staying connected in Japan can feel overwhelming, as it’s essential for getting around, using maps, staying in touch with family, and breaking language barriers. If you’re traveling with others and need internet on multiple devices, you’ll likely be choosing between a pocket WiFi or an eSIM. Both have their pros and cons, so the best option depends on your needs and budget. In this article, we’ll break it down and help you decide!
What is a Pocket Wi-Fi?
A Pocket WiFi is a small, portable device that gives you internet access by creating a WiFi hotspot. It works like a mini WiFi router but uses a SIM card to connect to mobile networks (like 4G or 5G). To use it, you need to insert a SIM card with a data plan, turn it on, and connect your phone, laptop, or tablet to its WiFi signal. It works just like a home WiFi but with no cables or software installation.
It’s a great option for travelers because it lets them stay online without using expensive roaming or public WiFi. Plus, they allow multiple devices to connect at the same time, making it perfect for groups or families traveling together.

Pocket WiFi in Japan: The Good and the Bad
A Pocket WiFi in Japan is a great choice for travelers who need to stay online while exploring the country. There are several rental companies available, such as SoftBank or Global Advanced Communications. They provide easy pick-up and return options at popular locations like airports, train stations, and hotels. One of the best features is that it lets you connect multiple devices at the same time, so a family or group can all use the internet from one device. Some pocket WiFi models can even handle up to 10 devices!
In terms of coverage and speed, a Pocket WiFi works in most areas of Japan, including cities like Tokyo and Osaka, as well as rural areas. The speed is fast enough for activities like browsing, using social media, or watching videos. For example, services like Japan Wireless offer unlimited data plans with speeds of up to 120 Mbps, allowing users to stream HD videos or browse the web without worrying about data limits.
Similarly, it is compatible with a wide range of devices—smartphones, tablets, laptops, and even cameras. Pocket WiFi makes it easier to stay connected without worrying about finding Wi-Fi or expensive roaming charges.
Although a Pocket WiFi is a popular and convenient option in Japan, it has some disadvantages. For instance, if you rent from companies like Japan Wireless, you need to carry around this extra device and keep it charged during your trip. For travelers already bringing their phones, cameras, and other gadgets, it can definitely be annoying.
You also have to pick up and return the device at specific locations, which can eat into your time in this beautiful country. For example, you may need to find the pickup desk at Haneda Airport, and then, before heading back home, return the Pocket WiFi at your departure airport.
On top of that, renting Pocket WiFi can be more expensive if you’re traveling alone. For example, Japan Wireless charges around ¥1,000-¥1,500 (USD 6.72-USD 10) per day, which can add up quickly to your vacation budget. It’s more expensive compared to eSIM providers in Japan, like Yoho Mobile, which can cost only ¥475 (USD 3.19) for a week.
Lastly, some Pocket WiFi providers, like Japan Wireless, limit your data speed after 3GB of usage. If you’re streaming videos or using a lot of data, your connection could slow down significantly after reaching that limit.
What to Consider When Choosing a Pocket WiFi
Data Plans and Fair Usage Policies
When choosing a Pocket WiFi plan, you need to be clear on two things: data plans and fair usage rules. Here’s what that means in simple terms:
Unlimited vs. Capped Data: Some plans say they offer “unlimited” data, but this isn’t completely true. What often happens is that you get a certain amount of high-speed data, and after you use it up, your speed is slowed down. For example, you might get fast internet for the first 10GB, and after that, the speed drops to something really slow (like 600 kbps), which can make watching videos or playing games harder.
Daily vs. Monthly Limits: Some Pocket WiFi plans give you a certain amount of data to use each day (like 3GB, 5GB, or 10GB). Once you reach the limit for the day, you’ll either get slower speeds or have no data left until the next day. Other providers such as eConnect Japan give you a total amount of data for the whole month or throughout your entire rental period. This could work better if you use data at different rates on different days, as you don’t have to worry about hitting a daily limit.
When picking a plan, think about how much data you’ll need. On average, most travelers use around 830 MB of data each day, but this depends on the activities you do, like streaming videos, browsing, etc.
Speed & Network Coverage
Speed and network coverage are the backbone when choosing a Pocket WiFi in Japan.
Choosing a provider with great speed and network coverage ensures you have reliable and fast internet access, no matter where you are in Japan. Some pocket WiFi companies only use one or two networks, while others use multiple networks to make sure you have good service almost anywhere. For example, NINJA WiFi uses SoftBank’s network, while CDJapan Rental gives you options with either WiMAX+5G or SoftBank networks. Some providers, like Mobal, say they use all four major networks (SoftBank, Docomo, AU, and Rakuten) to offer better coverage in more areas.
The strength of the WiFi signal can be different depending on where you are. In big cities, like Tokyo or Osaka, the signal is usually strong because these areas have many cell towers and good infrastructure. But if you travel to more rural or remote places, the signal can get weaker as there are fewer towers or coverage might be limited.

So, if you plan to visit both cities and rural areas in Japan, choose a Pocket WiFi provider with strong coverage in both types of areas. For example, NINJA WiFi works well both in major cities and more remote areas, making it a reliable option no matter where you go.
If you're going somewhere far from cities, it's a good idea to check the coverage map of your Pocket WiFi provider. This will show you where the signal is strong, so you can make sure you'll have a good connection during your trip.
Rental Costs
When choosing a Pocket WiFi in Japan, rental costs are an important aspect to consider.
First, rental costs are an important factor to consider, whether for daily or weekly pricing. Daily rentals can cost between ¥400 and ¥1,200 (about $2.70 to $8). For example, NINJA WiFi charges around ¥770 (about $4.75) per day, and you can get a discount if you rent for a longer period.
Weekly rentals are cheaper for longer stays, from ¥4,000 to ¥7,500 (about $27 to $50) for 7 days. Monthly rentals typically range from ¥5,000 to ¥10,000 (about $33.57 to $67.15), which is very affordable.
Deposit and Late Fee
When you rent a Pocket WiFi in Japan, the company might ask for a deposit, usually between ¥5,000 and ¥20,000 (roughly $33.57 to $134.29). The good news is you’ll get this deposit back once you return the device in good condition and on time.
However, if you return the device late, the company may charge you extra—up to ¥1,000 (about $6.71) per day. Some companies, like Y5Buddy, may even charge different rates depending on the country you’re in, so returning the device later could increase your costs.
Insurance
Many companies offer insurance to protect you from extra charges, but you’ll need to consider factors like your stay duration, data usage, and any additional fees before selecting the best plan for your needs. Here’s a quick breakdown:
Getting insurance could help you avoid paying a big fee if something happens to the device. Some companies, like Travel Wifi, offer insurance that can protect you from these high fees. This insurance costs about ¥115 (around $0.77).
Potential charges for lost or damaged devices: If you lose or damage the device you’re renting, you might be charged a hefty fee—up to ¥39,500 (about $265).
Battery Life & Portability
When renting a Pocket WiFi in Japan, it’s important to consider both battery life and portability. Most devices last between 6 to 12 hours on a single charge, though some, like the Jetpack 8800L, can last up to 24 hours depending on factors such as network type and data usage (heavy streaming uses more battery). Some providers, like eConnect Japan, even offer a free power bank.
Pocket WiFi devices also vary in size and weight. Smaller models, such as the Franklin T9 (weighing only 2.63 ounces and measuring 4.1 x 2.6 x 0.5 inches), are designed to be portable and easy to carry in your pocket or bag, making them convenient to take with you anywhere without feeling weighed down.
Pickup & Return Options
The pickup and return options matter a lot when deciding on a Pocket WiFi service in Japan. For pickup, many companies let you get your device at major airports like Narita or Kansai, while others offer delivery to your hotel or place of stay. For example, Japan Wireless lets you choose where you’d prefer to pick up your pocket device.
For returning, most providers give you a prepaid envelope to send it back, and you can drop it off at a post office or a red post box. Some, like Global WiFi, also let you return it at an airport counter.
It's important to return the Pocket WiFi before you leave Japan, or you may be charged a late fee of around ¥1,500 per day. Always double-check the return instructions with your provider since some may have specific rules.
Best Pocket WiFi Providers in Japan
Ninja WiFi
Ninja WiFi is a popular provider in Japan with simple and convenient service and easy pickup and drop-off at airports. They provide plans with 3GB, 5GB, or 10GB of high-speed data each day, so you can choose the one that fits your needs. However, if you exceed your data limit, extra charges may apply, and the internet speed can drop significantly, making it difficult to stream videos or make video calls.
Overall, Ninja WiFi is a reliable WiFi provider, but be mindful of your data usage to avoid extra fees.
Japan Wireless
Japan Wireless is a well-known provider of Pocket WiFi in Japan. They offer a plan that gives users access to unlimited data (though it’s not truly unlimited). There’s a fair usage policy in place, meaning users can enjoy high-speed internet without worrying about hitting a data cap, but speeds may slow down after using too much data.
One of its standouts is that it gives you a free power bank with the rental, which helps keep the device charged for longer. The service works all over Japan, from Hokkaido in the north to Okinawa in the south, making it perfect for tourists exploring the country.
Sakura Mobile
Sakura Mobile is a great option if you’re planning to stay in Japan for a while (a month or more). It offers unlimited data plans that give you reliable internet, even if you use a lot of data. Since it runs on SoftBank’s network, you’ll have good coverage almost anywhere in Japan.
However, Sakura Mobile’s devices can be bulkier than other options like NINJA WiFi. The upside is that their devices have a long battery life, lasting up to 20 hours, and can connect up to 15 devices at once. Sakura Mobile also provides customer support in English, making it a solid choice for those who don’t speak Japanese.
Mobal Japan Pocket WiFi

You need to sign up for at least 3 months, but after that, you can keep using it on a month-to-month basis.
The device is yours to keep, and Mobal offers easy setup and customer support in English, making it easier for international users.
eSIM vs Pocket Wifi in Japan
An eSIM is a digital SIM card that is already built into your phone, tablet, or smartwatch. You don’t need to put a physical SIM card in it. Instead, you activate it through software. This makes it easy to switch mobile carriers or plans without needing a new card. eSIMs let you make calls, send texts, and use the internet, just like regular SIM cards.
For people traveling to or within Japan, eSIMs are especially useful since they can easily switch to a local network without changing SIM cards. Many modern devices support eSIMs, making it a convenient way to stay connected while in Japan.
Related: What is an eSIM?
When deciding between the best eSIM provider or the best pocket WiFi in Japan, consider your travel style, and how much data you’ll use. eSIMs are especially useful for solo travelers or anyone who wants a quick, easy way to stay connected. Here are some benefits of using an eSIM in Japan:
-
No physical SIM card needed: Once activated, the eSIM works right away, so you won’t have to worry about picking up a physical SIM card upon arrival in Japan or waiting for it to arrive in the mail.
-
No extra device to carry: Unlike pocket WiFi, which requires you to carry it around and keep it charged, an eSIM is already on your phone or tablet, making it more convenient and lightweight.
-
Easy to buy and set up: You can purchase and activate your eSIM before your trip. As soon as you land in Japan, you’ll have internet access without any hassle.
Good for solo travelers: If you’re traveling alone and just need data for one device, an eSIM is often a more cost-effective and convenient choice compared to renting pocket WiFi in Japan. -
Cost-effective for light data users: If you don’t use a lot of data, an eSIM plan can be cheaper than renting a pocket WiFi device, especially if you’re only staying in Japan for a short period.
On the other hand, eSIMs have some downsides to consider. Not all devices support them, so you’ll need to check if your phone is compatible before opting for an eSIM in Japan. Setting up an eSIM can also be tricky for first-time users. Lastly, eSIMs may not be ideal for group travel, as connecting multiple devices can be difficult.
Cost Comparison: eSIM vs Pocket WiFi
eSIM in Japan: eSIMs are a good, cost-effective option for short trips, typically lasting between 3 to 10 days. For example, Yoho Mobile offers a 7-day unlimited data eSIM plan for $26.00, which is a great deal for solo travelers or anyone who only needs to connect one device.

eSIM vs Pocket WiFi in Japan: Which is best for you?
- eSIMs are the better option for most travelers, especially for short trips and individual use. They are easy to set up, cost less, and don’t require extra hardware.
- Pocket WiFi is better suited for longer stays or group travel. But they are more expensive, need to be rented, and take longer to arrive.
