Japan SIM Card for Tourists: Prices & Where to Buy
A Japan SIM card can mean several different products: a physical data SIM, a physical SIM with a Japanese phone number, or a digital travel eSIM. Those options solve different problems. Buying the first card you see at the airport may leave you without hotspot access, without a local number, or with a validity period that does not match your trip.
Quick recommendation: what should most tourists buy?
For most tourists, a travel eSIM is the simplest starting point when the phone is unlocked and eSIM-compatible: install it before departure and connect after landing without waiting at an airport counter. Buy a physical prepaid SIM when the phone has no eSIM support. Choose a voice-and-data SIM only when you specifically need a Japanese phone number, conventional calls, or SMS.
Travel eSIM
Install before departure. Best when mobile data is enough and the unlocked phone supports eSIM.
Physical prepaid SIM
Reserve airport pickup or delivery when the unlocked phone needs a removable SIM.
Voice-and-data SIM
Check the number type, call and SMS terms, device requirements, and any ID rules.
Need data only? Compare Japan eSIM plans by trip length, total allowance, daily allowance, and post-limit speed.
This guide compares the main options, gives current price examples, explains where tourists can buy a SIM card in Japan, and shows what to check before paying.
Japan eSIM vs physical prepaid SIM vs roaming
The card format does not determine the service. A physical SIM can be data-only, while some providers sell eSIMs with voice service. Compare the number, data rules, hotspot policy, validity, and setup requirements—not just “SIM” versus “eSIM.”
| Feature | Travel eSIM | Physical tourist SIM | Voice-and-data SIM | Home roaming |
|---|---|---|---|---|
| Buy before arrival | Yes | Yes, if delivered or reserved | Often | Already installed |
| Physical slot needed | No | Yes | Depends on product | No change |
| Japanese number | Usually no | Usually no | Yes, when stated | No |
| Regular calls and SMS | Usually no | Usually no | Yes | Uses home number |
| Airport collection | Not required | Common option | May be available | Not required |
| Hotspot | Plan-specific | Plan-specific | Plan/device-specific | Carrier-specific |
Best SIM card for Japan by traveler type
There is no single best SIM card for every visitor. The best option is the one whose service rules match the trip.
Data-only travel eSIM
Choose it when the phone is unlocked and compatible, app-based communication is enough, and you want to keep the home SIM installed. There is no airport queue, inventory risk, or card swap.
Physical tourist data SIM
Choose it when the phone has an unlocked physical SIM slot. Confirm size, bands, APN, hotspot rules, pickup point, and where the home SIM will be stored.
Voice-and-data SIM
Choose it only when a real Japanese number, conventional calls, or SMS is necessary. Identity checks and separate call charges may apply.
Pocket WiFi
Useful when several people stay together and not every phone supports eSIM. The router must be collected, charged, carried, and returned.
Ezigo Japan plans are data-only and support hotspot sharing. The current range includes fixed Total data, 2GB/day and 3GB/day plans, and an Unlimited family with 1GB of high-speed data per day followed by data at up to 5Mbps. Plan networks and speed rules differ, so choose the plan family before choosing the number of days.
Japan Wireless and Sakura Mobile sell physical data-only travel SIMs with pickup or delivery options. Mobal advertises voice plans with Japanese 070, 080, or 090 numbers, and JAL ABC lists prepaid voice-and-data products at selected airport counters. Mobal says customers collecting a voice SIM in Japan must show an order confirmation and passport; JAL ABC states that ID is required for its voice SIM.
For groups, see the full Japan eSIM vs Pocket WiFi comparison before choosing a router only because “unlimited” appears in the product name.

How much does a Japan SIM card cost?
A Japan SIM card for tourists can cost only a few US dollars for a small travel eSIM allowance or several thousand yen for an airport physical SIM. A voice-and-data plan with a Japanese number usually costs more than a data-only product.
JAL ABC lists a 3GB/7-day eSIM at ¥2,700 and a 5GB/30-day physical SIM at ¥3,000. Japan Wireless lists its Standard physical SIM at US$18.60 for 7 days and US$28.30 for 30 days, while the Premium family costs more and uses different hotspot rules. These are not direct equivalents.
Current Ezigo Japan eSIM price examples
Ezigo’s product selector starts at US$2.55. The plan families below solve different needs; confirm the live selector before checkout.
Total data
From $2.55 USD
1GB to 50GB. Data stops when the total allowance is used. Best when you can estimate the whole trip.
Standard Daily
2GB/day or 3GB/day
Continues at up to 384Kbps after the daily high-speed amount, until the next reset.
Unlimited
1GB high speed/day
Then continues at up to 5Mbps. “Unlimited” does not mean unlimited full-speed use.
| Plan family | Selected examples | After high-speed data | Network information shown | Choose it when… |
|---|---|---|---|---|
| Total |
| Data stops | 5G on NTT Docomo, Rakuten, KDDI/au | You want a fixed budget |
| Standard Daily |
| Up to 384Kbps until reset | 4G/LTE on NTT Docomo and IIJ | You want fresh daily data |
| Unlimited |
| After 1GB/day, up to 5Mbps | 4G/LTE/5G on SoftBank and KDDI | Continuous data matters most |
At 384Kbps, messaging and light navigation may remain possible, but video, large uploads, and laptop work will be constrained. Up to 5Mbps is more useful for routine browsing, navigation, calls over data, and some video, although actual performance depends on coverage, congestion, and the device.
Use the Japan data calculator and usage guide instead of buying the largest plan by default.
Choose a Japan plan by how the data behaves
Compare fixed Total data, daily high-speed allowances, and continued-data Unlimited plans. All current Japan options are data-only and support hotspot sharing.
View Japan eSIM plansWhere to buy a SIM card in Japan
Online before departure
Compare terms at home, receive an eSIM by email, and install over stable Wi-Fi. This avoids airport queues, stock, and opening-hour risk.
Counters and vending machines
The official directory lists mobile counters and machines across terminals. Check the current terminal and hours before flying.
Terminal-specific services
Terminal 1 has a prepaid SIM vending machine, while Terminal 3 lists staffed arrival and departure counters with different hours.
Machines and counters
The official directory lists services in Terminals 1 and 2. Some machines are open 24 hours; staffed locations use separate schedules.
Buy an eSIM online before departure
This is the most predictable route when the phone supports eSIM. You can compare the plan rules at home, receive the QR code by email, install over stable Wi-Fi, and keep the profile ready for arrival. Buying online does not remove the compatibility check: the phone must still be carrier-unlocked and eSIM-compatible.
Buy at Narita Airport
Narita’s official service directory lists mobile and SIM counters as well as vending machines. JAL ABC sells selected products at its Terminal 1 and Terminal 2 arrival counters. Check the Narita Airport mobile-service page shortly before departure. JAL ABC also states that counter staff do not perform APN setup for customers.
Buy at Haneda Airport
Haneda’s directory lists SIM and mobile-service points in Terminals 1, 2, and 3. The airport currently lists a prepaid SIM vending machine in Terminal 1 and staffed services in Terminal 3. Check the Haneda SIM and mobile-service directory for your actual terminal.
Buy at Kansai International Airport
Kansai Airport lists SIM vending machines and counters in Terminals 1 and 2. Some vending machines are open 24 hours, while staffed services follow their own schedules. Verify the current location on the Kansai Airport Wi-Fi and SIM page.
Order a physical SIM for pickup or delivery
Sakura Mobile and Japan Wireless advertise airport pickup or delivery options, while Mobal lists pickup points and worldwide delivery. Read the collection instructions carefully: some providers need a passport or order confirmation, and accommodation delivery depends on the hotel’s parcel policy.
Buy at an electronics store or convenience store
Large electronics stores and some convenience or travel retailers may stock tourist data SIMs, but availability, languages, setup support, and product range vary by branch. Do not rely on a convenience store as your only arrival plan. A card on the shelf may be data-only and may start its validity on activation rather than purchase, so check the package terms before paying and photograph them before discarding the packaging.
Physical SIM or eSIM: which is better in Japan?
Preparation matters
- The exact phone supports eSIM and is unlocked.
- Mobile data is enough.
- You want the home SIM left in place.
- You want to avoid airport pickup.
The device needs a card
- The phone has an unlocked slot but no eSIM.
- You prefer a removable card.
- You have checked APN, hotspot, size, and validity.
- You can safely store the home SIM.
A Japanese number matters
- Work, study, calls, or a service requires one.
- App-based calling is insufficient.
- You accept ID, billing, and cancellation rules.
- The phone supports the stated VoLTE requirements.
Your home plan already fits
- Japan is included at an acceptable price.
- The allowance covers your actual use.
- You understand daily-pass triggers.
- You want to retain your home number without dual-SIM setup.
What to check before buying a Japan SIM card
- Carrier lock: the phone must accept another provider. On iPhone, check Settings → General → About → Carrier Lock. Android wording varies.
- Exact model: regional variants can differ. An unlocked phone may still lack eSIM or a physical SIM tray.
- Service type: confirm whether the product is data-only or includes a Japanese number, calls, and SMS.
- Allowance behavior: check whether data stops, slows, or resets. Plan validity and a daily high-speed reset are not the same thing.
- Hotspot rules: “supported” does not always mean unlimited tethering. Some products impose a separate hotspot allowance.
- Activation and validity: identify what starts the clock—installation, manual activation, or first connection in Japan.
- APN and roaming: some physical cards need manual APN entry. Travel eSIMs commonly require data roaming on the eSIM line.
- Pickup evidence: save the order confirmation, terminal, counter name, hours, and any passport requirement offline.
- Home-line charges: incoming OTP texts may work, but calls, outgoing SMS, voicemail, or roaming data can still create charges.
Use Ezigo’s device compatibility checker for a first check, then confirm the exact model with the manufacturer or carrier if the regional variant is unclear.
How to activate a Japan SIM or eSIM
Travel eSIM setup
- Check the device. Confirm carrier-unlocked status and eSIM support.
- Choose the plan. Match allowance behavior and validity to the itinerary.
- Open the delivery email. Keep the QR code visible on a second screen or device.
- Install over Wi-Fi. Label the profile “Japan” and retain the manual activation details.
- Connect after landing. Select the Japan eSIM for mobile data, enable data roaming on that line, and turn off unwanted mobile-data switching.
Ezigo sends installation details by email after payment. Follow the instructions supplied with the purchased profile because activation policies can differ between products.
Physical prepaid SIM setup
- Power off and swap carefully. Remove the home SIM only if needed and store it safely.
- Insert the correct size. Restart the phone after placing the prepaid SIM.
- Enter the APN. Copy the supplied name, username, password, and authentication type exactly where required.
- Select mobile data. Enable only the settings specified by the provider.
- Test before leaving. Open a webpage and map while you are still near the pickup point.
If it does not connect, check the APN, restart the phone, toggle airplane mode, and confirm that the device is unlocked. Do not repeatedly change unrelated network settings; use the provider’s support instructions.
Common mistakes to avoid
- Assuming every physical SIM includes a Japanese number.
- Buying an airport SIM without checking terminal, hours, stock, or setup support.
- Treating “unlimited” as unlimited full-speed data.
- Choosing only by price and ignoring validity, hotspot limits, and post-threshold behavior.
- Waiting until arrival to discover that the phone is carrier-locked or eSIM-only.
- Removing the home SIM without planning for OTP messages or safe storage.
- Activating a time-limited product too early.
- Expecting a data-only travel eSIM to receive conventional SMS or Japanese verification codes.
Frequently asked questions
Do I need a SIM card for Japan?
You need a mobile-data solution for reliable navigation, translation, bookings, and communication away from Wi-Fi. It can be a travel eSIM, physical tourist SIM, local voice-and-data SIM, Pocket WiFi, or acceptable home-carrier roaming. A physical SIM is not mandatory.
Which SIM card is best for tourists in Japan?
A travel eSIM is usually best for a short, data-first trip with an unlocked compatible phone. A physical data SIM is better when the phone has no eSIM. A voice-and-data SIM is the correct choice when a real Japanese number or conventional calls and SMS are required.
How much is a SIM card in Japan?
Examples checked in September 2026 include an Ezigo eSIM from US$2.55, JAL ABC’s 3GB/7-day eSIM at ¥2,700, its 5GB/30-day physical SIM at ¥3,000, and Japan Wireless physical SIMs from US$18.60 for 7 days. Compare data rules and validity before treating them as equivalents.
Where can tourists buy a SIM card in Japan?
Buy online before departure, reserve airport pickup, use selected airport counters or vending machines, request hotel or post-office delivery from some providers, or shop at city electronics retailers. Check the exact provider, terminal, opening hours, stock, and setup process.
Can I buy a SIM card at Narita, Haneda, or Kansai Airport?
Yes. All three airports list SIM or mobile-service facilities. The terminal, location, opening hours, brands, and inventory differ. Use each airport’s official directory shortly before travel.
Can I use my US phone in Japan?
Many modern US phones work in Japan, but the exact model must be unlocked and compatible with the chosen SIM or eSIM. Some US iPhone models are eSIM-only, while older devices may lack eSIM or useful Japanese network bands.
Does a Japan tourist SIM include a Japanese phone number?
Usually not. Many tourist SIMs and travel eSIMs are data-only. A Japanese number is included only when the provider explicitly sells voice or voice-and-data service and states the number type and identity requirements.
Can I use hotspot with a Japan SIM card or eSIM?
It depends on the product. Ezigo Japan plans support hotspot sharing, while physical SIM providers publish plan-specific conditions. Tethered devices use the same allowance, and reduced-speed service can make laptop work impractical.
Is it worth getting a SIM card in Japan?
Yes, if home roaming is expensive or you want dependable mobile data away from Wi-Fi. An eSIM is often the simplest form for a short trip; a physical or voice SIM becomes worthwhile when the device or communication requirement demands it.
Can I keep my normal phone number while using a Japan eSIM?
Usually yes on a dual-SIM phone. Keep the home line installed and select the Japan eSIM for mobile data. Calls, outgoing SMS, voicemail, or accidental roaming data on the home line may still be charged.
Final recommendation
Start with the service requirement, not the card format. A tourist who needs data can usually install a Japan eSIM before flying and avoid airport pickup. A traveler whose phone has no eSIM should pre-order a physical tourist SIM. Someone who needs a Japanese number should buy a product that explicitly includes voice and SMS and complete any required identity verification.
For a data-only trip, compare Ezigo’s Total, Daily, and Unlimited options on the Japan eSIM product page. If you are still comparing providers, read Best eSIM for Japan. For broader arrival, transport, and itinerary preparation, continue with the Japan travel guide.
