Can You Buy a SIM Card / eSIM at Lawson or FamilyMart in Japan? Brands, Prices & What to Know (2026)

To put it simply, while you can purchase prepaid SIM cards at Lawson and FamilyMart in Japan, there are major caveats: most cannot be used immediately (requiring later delivery), and they are not available in every store. Meanwhile, Seven-Eleven also sells SIM cards in a extremely small fraction of its locations.

If you want to learn more details about the SIM card situation at Seven-Eleven, check out our detailed guide here. In this article, we will focus specifically on Lawson and FamilyMart, covering available brands, pricing, and critical points to keep in mind before buying.

1. Can You Buy Them at Airport Convenience Stores (Narita, Haneda, KIX)?

One of the most common questions international travelers ask is whether they can buy a SIM card at airport convenience stores immediately upon arrival. While convenience stores located inside major airports like Narita, Haneda, and Kansai International Airport (KIX) do stock SIM cards, availability is never guaranteed due to extremely fast turnover rates.

Airports offer alternative solutions like SIM card vending machines and dedicated service counters where you can easily purchase a card. However, prices at airport physical shops are significantly higher compared to online rates. Instead of buying directly at the airport, ordering a SIM card online in advance for airport pickup will save you money and cut down your waiting time significantly.

2. SIM Cards at FamilyMart: Brands & Pricing

FamilyMart offers prepaid SIM options from 2 primary brands:

• IIJmio Selectable SIM Card (えらべるSIMカード)
• BIC SIM Selectable SIM Card powered by IIJ

The standard package for these selectable SIM cards costs approximately 3,300 JPY (tax included).

This means you cannot connect to the internet on the spot. If you need immediate internet connectivity right after landing, this option is not suitable for you.

3. SIM Cards at Lawson: Brands & Pricing

At Lawson, you will generally find the following brand selections:

• IIJmio Selectable SIM Card
• Japan Travel SIM
• DXHUB Prepaid SIM Card

Among these options, the physical Japan Travel SIM can be activated immediately after purchase. Data capacity options range from 3 GB to 55 GB, with prices starting from 2,200 JPY (tax included).

Typically, you must select your desired plan using the "Loppi" multimedia terminal inside Lawson stores and pay at the cash register. Note that physical Lawson stores offer data-only plans without SMS or voice functionality.

4. Lawson Also Offers eSIMs: A Convenience Store First

In February 2024, Lawson launched the sale of "Japan Travel SIM (eSIM)", becoming the first convenience store chain in Japan to offer prepaid eSIMs directly to consumers.

Pricing & Plans (Valid for 30 Days)

• 3 GB: 2,480 JPY
• 55 GB: 5,780 JPY
• (A total of 7 capacity tiers are available)

Purchasing Steps via Loppi Terminal

1. Select your preferred data plan using the in-store Loppi terminal and print out an application voucher.
2. Pay at the register to receive a paper receipt printed with a QR code and entry code.
3. Connect to a Wi-Fi network (such as at your hotel), access the designated registration portal, and scan the QR code to download the eSIM profile.

Note: Active Wi-Fi is strictly required for configuration. Because free in-store Wi-Fi services have been discontinued across most Japanese convenience stores, you must set up your eSIM using hotel or public Wi-Fi access points.

5. Crucial Point: SIMs Are "Not Available in All Stores"

This is a frequently overlooked but critical point: prepaid SIMs and eSIMs sold through Lawson and FamilyMart are not stocked in 100% of store locations.

For example, "Japan Travel SIM" is limited to select locations within Lawson and NewDays (convenience stores inside major train stations and Shinkansen gates). Furthermore, tourist-focused prepaid SIMs are often restricted to specific high-traffic locations, such as designated stores at Kansai International Airport (KIX Terminal 1, 2nd & 4th floors).

Do not assume that every neighborhood store will have stock. We strongly advise checking participating store locations in advance.

6. Notice: Foreign Tourists Cannot Buy Voice Call SIMs

While some product lines offer voice call options, short-term travelers cannot realistically purchase them due to legal restrictions. Under Japan’s Act on Identification of Subscribers by Mobile Voice Communications Carriers, strict identity verification (official ID & proof of residence) is legally required for SIM contracts with voice features. Data-only SIMs do not carry this requirement.

Even if you purchase a FamilyMart "Selectable SIM Card," completing the activation requires a monthly contract tied to a registered Japanese address. As a result, convenience store SIM products available for short-term visitors are limited to data-only plans. For making calls, voice communication apps like LINE, WhatsApp, or Skype are the recommended solution.

8. Real Experiences from Overseas Travelers

On travel community boards like Tripadvisor’s "Japan Forum," visitors frequently share their experiences purchasing SIM cards at Japanese convenience stores.

"I ordered a B-mobile SIM card on Amazon.co.jp to pick up at a Lawson near Narita Airport. (Be careful not to order too far in advance, as Lawson only holds packages for about 10 days). After installing the physical SIM and setting up the iOS profile, it started working within minutes. A 5 GB / 21-day plan was more than enough for my 19-day trip."

Buying Data Sim Card in Japan

"While you can deliver Amazon orders to Lawson or FamilyMart at KIX Terminal 1 (2nd floor), delivery availability can fluctuate depending on system settings. Delivering to your nearby hotel or a store outside the immediate airport terminal is often more reliable."

"Network speeds across the major 3 networks (NTT Docomo, au, SoftBank) are generally similar. Your main decision criteria should be price, validity period, and setup convenience."

Buying Data Sim Card in Japan

The clear takeaway from travelers is that relying on same-day convenience store pickups without advance planning can cause unexpected delays.

9. Checklist Before Buying at a Convenience Store

Keep these essential key points in mind before heading to a store:

• FamilyMart "Selectable SIM Cards" cannot be used on the same day (require mail delivery).
• Lawson and NewDays SIM products are sold in select stores only.
• eSIM plans sold in stores have fixed limits on validity and data tiers.
• Voice call/SMS capabilities require Japanese official identity verification.
• Ensure your smartphone is SIM-unlocked and compatible with Japanese network frequencies before traveling.

10. Need Connectivity Right Upon Arrival? Choose an Pre-configured eSIM

As covered above, buying a SIM card at a convenience store comes with friction—ranging from mail delivery delays and mandatory web registrations to limited store stock. Spending your first few hours hunting down store locations or troubleshooting missing Wi-Fi can drain your precious travel time.

With Travel Mobile's eSIM, you can complete your configuration at home before departure. Connect directly to NTT Docomo’s high-speed 5G network the moment you turn off airplane mode after landing, giving you instant access to maps, messaging, and navigation tools.
