Staying connected in Japan isn’t always easy for visitors. While the country is well wired overall, getting reliable internet right after landing can be a challenge. Public WiFi spots are often slow, limited or require complicated sign-ins. Buying or renting a SIM card or eSIM can be confusing, especially if your phone isn’t unlocked or compatible.
That’s where pocket WiFi comes in. It offers fast, stable internet that works with any device, keeps you connected anywhere in Japan, and lets you avoid the hassle of phone settings or network issues. Whether you’re traveling alone or with family, a pocket WiFi rental is a simple way to stay online and enjoy your trip worry-free.
Why Choose Pocket WiFi for Your Trip to Japan
Pocket WiFi is a small, portable device that creates a personal WiFi hotspot wherever you go. It works with all your WiFi-enabled devices—smartphones, tablets, laptops—without needing to swap SIM cards or change phone settings. This makes it a great option if your phone doesn’t support eSIM or is locked to a carrier.
One pocket WiFi device can connect multiple devices at once, making it perfect for families or groups traveling together. This often saves money compared to buying separate SIM cards for each person.
Pocket WiFi also offers larger or unlimited data plans, so you won’t have to worry about running out of data. Because it uses Japan’s major mobile networks—like docomo—you get wide coverage and fast speeds, even outside of big cities.
If you want a simple, plug-and-play internet solution that works reliably throughout your trip, pocket WiFi is a smart choice.

Key Questions to Ask When Renting Pocket WiFi in Japan
Before renting a pocket WiFi, it’s important to ask the right questions to find the best service for your trip.
Here are 10 questions to help you choose wisely:
1. Is the Company English-Friendly?
If you can’t speak Japanese and are worried about communication, look for full English support before and during your trip to avoid confusion or delays if issues come up. Just because a Japan pocket WiFi rental company has an English webpage, doesn’t mean they’re English-friendly.

2. How and Where Can I Pick Up and Return the Device?
Many companies offer flexible options for getting your pocket WiFi: you can have it shipped to your hotel, to a post office at the airport, or pick it up at the company’s airport counter. It’s best to book a few days before your trip. Not only does this help to ensure the device you want is in stock, especially during busy travel seasons, but it’s also usually cheaper than renting on the spot at the airport. Returning though, is as simple as mailing it back in a prepaid envelope or dropping it off at your hotel concierge.

3. Does Pocket WiFi Offer Wide, Reliable Coverage Across Japan?
Providers that use the docomo network give the best coverage, including rural and mountainous areas. This also covers trips to onsen (hot spring baths) and skiing, as these activities are almost entirely located in rural areas. Sakura Mobile uses docomo’s reliable network to keep you connected nationwide.
4. Is the Internet Speed Fast Enough for My Needs?
Look for speeds around 70 Mbps or higher for smooth streaming and video calls. Some providers even offer high internet speeds above 100 Mbps.
5. Can I Choose a Data Plan That Fits My Usage?
Assess and pick a plan with enough data for your daily needs. For instance, if your internet usage is limited to browsing news articles and checking social media, you may only require around 500 MB (megabytes) of data per day. However, if you plan to upload travel videos to YouTube, make video calls, or connect multiple devices to a single pocket WiFi (such as smartphones, tablets, and laptops), you might need up to 10 GB (gigabytes of data)
Key Terms to Know When Choosing a Plan:
- MB (megabyte) and GB (gigabyte): These measure how much data you use. For example, sending 100 emails uses about 2 MB, while streaming one hour of HD video can use up to 900 MB. 1 GB equals 1,000 MB.
- Mbps (megabits per second): This measures your internet speed. Higher Mbps means faster downloads and smoother video calls. For travel data plans, speeds around 10-50 Mbps are typically enough for most online activities. Sakura Mobile’s pocket WiFi offers reliable speeds up to 150 Mbps, ensuring smooth streaming, browsing, and video calls.
- Data Allowance: The total data you can use before your speed slows or extra charges apply.
Sakura Mobile offers flexible options, including unlimited plans and affordable top-ups if you use more data.

6. Will My Connection Slow Down or Stop After Hitting Data Limits?
Sometimes your speed slows down after reaching a daily data limit—even on “unlimited” plans. For example, if your plan allows 300 MB per day, once you hit that, streaming and browsing can become very slow until the next day or until you buy more data. Other plans give you a total data limit for your entire trip; if you use it up early, your connection stops until you purchase extra data. Before renting, check if the company offers affordable data top-ups and a way to monitor your usage.

7. How Long Does the Battery Last?
Most pocket WiFi devices nowadays last about 8 hours on a full charge, depending on how often you use them, which is enough for a fully day of sightseeing. If you expect to be out longer, consider carrying a portable charger.
8. Is the Device Compact and Easy to Carry?
Pocket WiFi devices may differ in size. If you’re looking to be out the whole day, you’ll want a small, lightweight device to carry all day comfortably.
Insider Tip:
Sakura Mobile’s pocket WiFi devices are lightweight, have a batter life up to 20 hours of use, and support up to 15 connected devices (5 is recommended). Battery life may vary depending on how many devices are connected and how much they’re used.
9. Are the Rental Prices Fair with No Hidden Fees?
Watch out for extra fees like late return charges or data overage costs. A good rule of thumb is to look for competitive pricing for Pocket WiFi rentals in Japan similar to those in other travel-friendly countries; not everything in Japan is expensive, and Sakura Mobile’s pricing is clear with no surprises. So you know what you’ll get.
10. What Do Other Customers Say About the Company’s Service?
Checking reviews helps confirm the company’s reliability and customer support quality.

Pocket WiFi vs. SIM/eSIM: Which is Best for You?
Both pocket WiFi and SIM cards or eSIMs offer ways to stay connected in Japan, but each has its own advantages.
Pocket WiFi works with any WiFi-enabled device, making it ideal if you have multiple devices or travel with family or friends. It requires no phone unlocking or setup—just turn it on and connect. Pocket WiFi also often comes with larger or unlimited data plans, which is excellent if you need steady, high-speed internet.
SIM cards are physical chips inserted into phones, whereas eSIMs are digital versions that don’t require physical insertion. Both typically offer lower costs per device. They are a good option if you travel alone with an unlocked phone that supports eSIM. However, if your device isn’t locked to your home carrier or is incompatible, SIMs may not work. Also, each device needs its own SIM or eSIM.
In short, choose pocket WiFi if you want easy setup, multiple device connections, and reliable coverage. Choose SIM or eSIM if you prefer a lower-cost option for a single, compatible device
