Let’s get you connected, shall we?
Why You Need Internet Access in Japan
Public Wi-Fi, is often surprisingly limited. Sure, you might find free Wi-Fi in cafes, convenience stores, and in train stations, but it’s far from being consistent enough to rely on, particularly if you’re in a pinch and you need to book a hotel room, find your way to your next destination, or call for a wheelchair-friendly ride.
Then there’s the big one… translation apps. There may be some that allow you to download vocabulary to use offline, but for the most part, using the likes of Google or ChatGPT to get by with their translations requires an internet connection. Very few tourists speak or read Japanese, which is probably why you’re on our website in the first place, so when you’re in a country where the majority of folks don’t speak English, you’ll feel like you’re without a precious lifeline if you can’t connect to your translation app to ask where the accessible bathroom is!
So What Are Your Options?
There are four main ways tourists can usually get online while visiting Japan:
| Option | Best For | Pros | Cons |
|---|---|---|---|
| SIM Card | Solo travelers with unlocked phones | Cheap, simple | Requires SIM swap |
| eSIM | eSIM-compatible phones | No physical card needed | Not all phones supported |
| Pocket Wi-Fi | Families, groups, and power users | Shareable, unlimited data | Need to carry/charge the device |
| Roaming | People who hate tech hassles | No setup, just works | Usually expensive, not tailored |
SIM Cards in Japan: What You Need to Know
Getting your hands on a Japanese SIM is pretty straightforward. You’ll find tourist-friendly providers who offer websites in English, as well as no long-term contracts, and plans that are tailored for shorter stays – usually with data only.
After reviewing several sources and speaking to visitors who have traveled to Japan before, we’ve managed to whittle your options down to our top three picks, summarised below:
- Mobal: OUR TOP PICK. Reliable, supports tethering, SIM ships worldwide, and some of the proceeds go to charity. They are also the only provider that offers an actual voice plan if you need to make a call or need to be reached.
- Sakura Mobile: Great coverage, easy airport pickup, slightly more expensive.
- IIJmio / b-mobile: Budget-friendly, available in stores like BIC Camera.
PRO TIP: Ensure your phone is unlocked and not restricted to a single carrier before traveling to Japan; otherwise, any attempt to use a local SIM card will be futile.
eSIMs: Instant Internet Without the Plastic
The benefit to eSIMs is that they are digital SIMs that are built into your phone; therefore, there’s no need to insert any fiddly little SIM cards into the side of your device. Providing your phone supports eSIMs (which most iPhones and newer Androids do), then all you need to do is scan a QR code and be connected before your plane even touches the tarmac (though only if you’re allowed to use your devices mid-air )
Advantages:
- No waiting for delivery
- No physical card to lose
- Activate instantly with a QR code
Top tourist options include:
Pocket Wi-Fi: For Groups, Power Users & Netflix Addicts
If you’re traveling in a group and you want multiple devices to be connected to the internet, then it may be worthwhile to explore pocket Wi-Fi as an option. These portable routers fit in your pocket and are handy to carry around with you for constant Wi-Fi, on the go! It’s great if you’re:
- Traveling with family or friends
- Using a laptop or tablet
- Wanting unlimited data
Top Wi-Fi options include:
- Japan Pocket WiFi (also offers bundle options with the JR Pass or regional rail passes)
- Ninja WiFi
You can pick them up at airports or have them delivered to your hotel. However, remember that it’s one more device to carry and charge.
Roaming: Using Your Home SIM in Japan
Check with your carrier before you go — some plans include Japan in their international roaming (like T-Mobile US), while others charge hefty fees.
Using your home carrier’s roaming service has its perks: there’s no setup required, and it works as soon as you land. However, it often runs slower than local networks, may not support Japanese emergency alerts, and can be expensive unless covered by your existing plan.
Where to Get a SIM or Pocket Wi-Fi
Depending on the solution you choose. The provider may specify a certain type of delivery if ordering before you arrive, but there are also options to get connected after you arrive:
- At the airport: Tokyo Narita, Haneda, and Osaka Kansai have plenty of counters.
- Convenience stores: Some offer SIM cards, but not always tourist-friendly.
- Electronics stores: BIC Camera, Yodobashi Camera, but don’t forget to bring your passport!
- Delivered to your hotel: Easy and stress-free with services like Mobal.
Which Option Is Best for You?
Every traveler’s needs are different, but here are some suggestions.
- Solo Traveler: SIM / eSIM
- Couples: Pocket Wi-Fi or two eSIMs
- Families: Pocket Wi-Fi
- Business Travelers: SIM / eSIM or roaming if work covers it
- Accessibility-Focused Travelers: eSIM + backup option
Accessibility Tips
For travelers with mobility or communication needs, eSIMs offer the convenience of avoiding physical handling the small SIM cards and pin to open the SIM card tray. Pocket Wi-Fi can be especially helpful for powering larger assistive devices, while a reliable internet connection is essential for using maps, accessible ride apps, and translation tools. It’s also important to carry a backup method, such as saving maps offline or keeping emergency contacts stored locally.
Final Recommendations
Still unsure? Here’s our TL;DR:
- Want the easiest setup + global impact? → Get a Mobal SIM/eSIM
- Need unlimited data for the whole group? → Rent a Pocket Wi-Fi
- Only visiting for a few days and don’t want to think too hard? → Check if your roaming plan includes Japan
And remember, Japan is an incredible destination. Staying connected just helps you enjoy it more, without getting lost in the process.
