Narita or Haneda SIM vs online eSIM: 2026 prices compared

Short answer: as of August 2026, buying a prepaid SIM at a Narita or Haneda counter usually costs more per gigabyte than ordering an eSIM online before you fly. A 10GB/30-day SoftBank prepaid SIM sold through the airport rental counters is listed at ¥6,600 including tax, while Ubigi’s 10GB/30-day Japan eSIM is listed at US$16.50 (roughly ¥2,600). The airport counter buys you something else instead: a physical card, staff to hand it over, and a fallback if your phone cannot take an eSIM.

This page compares what the airport actually sells, at what published price, against what the main eSIM providers publish online — and then sets out the cases where walking up to a counter is still the sensible move.

All prices below are the figures published on each company’s own page as of August 2026. Yen conversions use an exchange rate of about ¥159 to US$1 (reference rate for 21 August 2026); rates move, so treat conversions as approximate.

What do SIM counters at Narita and Haneda actually sell?

Haneda Airport’s official service listing shows mobile counters and vending machines spread across all three terminals. Terminal 1 has an AnyFone JAPAN vending machine at B1F Marketplace North (05:00–24:00). Terminal 2 has a Mobile Center on 3F of the international departure lobby (07:00–22:00) and a J WiFi & Mobile / GLOBAL WiFi desk on 2F arrivals (05:45–23:00).

Terminal 3, where most international arrivals land, has the widest choice: a Mobile Center on 2F arrivals (06:30–23:00), an AnyFone JAPAN counter also on 2F arrivals (06:00–23:00), and a second Mobile Center plus XCom Global upstairs on 3F.

Those hours matter more than the price for some travellers. If your flight lands at Haneda at 01:00, most of those desks are shut, and the Terminal 1 vending machine is on the wrong side of the airport from an international arrival.

A third route sits between the two: order online, collect a physical SIM at the airport. Mobal, for example, publishes collection points at the JAL ABC arrival counter on 2F of Haneda Terminal 3 (04:00–01:00 daily), the JAL ABC counter in the Narita Terminal 1 North Wing arrival lobby (from 06:30 until one hour after the last flight arrives), and a Travelex counter at B1 of Narita Terminal 2 station (07:00–21:00). You pay online, but you still have to find the desk.

How much does an airport SIM cost at Narita or Haneda?

The clearest published price list for the SIMs sold through these airport channels is SoftBank Global Rental’s prepaid page. These run on SoftBank’s network, are data-only with no calling or SMS, and the page states that all prices include consumption tax. It also states that data top-up is not available — when the allowance is gone, it is gone.

AnyFone JAPAN, whose vending machines and counters appear at Narita, Haneda, New Chitose and Chubu, publishes a wider line-up on its own site, including unlimited-data cards that the rental page does not list. As of August 2026 it shows 1GB/4 days at ¥3,300, 3GB/5 days at ¥3,960, unlimited for 7 days at ¥7,150, unlimited for 15 days at ¥8,800, 10GB/30 days at ¥6,600 and 50GB/90 days at ¥9,900.

The two pages agree on the fixed-data tiers but not on the full catalogue, and AnyFone’s own list is not strictly linear: an unlimited 14-day physical SIM appears at ¥7,920 while unlimited 15 days is ¥8,800. If a specific tier decides your purchase, check the price on the machine or counter in front of you rather than assuming the web list is current.

How much does an online eSIM for Japan cost?

Online eSIM providers publish in US dollars and generally undercut the counter, particularly on fixed-data plans. The figures below are from each provider’s own Japan page as of August 2026.

Read the word “unlimited” carefully. Ubigi’s unlimited 15-day plan is described on its own page as 30GB of full-speed data, after which the connection is optimised to 2 Mbps for the rest of the validity period — enough for maps, messaging and email, not for high-bitrate video. Airalo lists Japan unlimited packages on SoftBank plus one other network.

Network coverage differs too. Ubigi’s Japan plans run on KDDI and NTT Docomo with 4G and 5G, and its pages describe “Smartstart” activation, where validity begins on arrival in Japan rather than at purchase. That detail matters if you buy a week ahead of your trip.

Airport SIM vs online eSIM: which is cheaper for the same trip?

Comparing like for like is the only fair way to do this. These pairings use the published August 2026 prices above.

The pattern is consistent at the short and medium end: the counter charges a premium of roughly ¥2,500–¥4,000 for the same amount of data on a typical one- to four-week trip. At the long end, the ¥9,900 50GB/90-day card works out under ¥200 per gigabyte, which the short-validity eSIM tiers do not match.

Two costs do not appear in either table. Online eSIMs are billed in US dollars, so your card issuer may add a foreign-transaction fee — worth checking before you assume the dollar price is the final price. And the airport counter costs time: it is a physical stop after immigration and baggage reclaim, and how long it takes depends on how many people are ahead of you.

When is buying at Narita or Haneda still the right call?

Price is not the only variable, and there are situations where the counter is the better option regardless of the premium.

• Your phone does not support eSIM. Older handsets and some region-specific models cannot install one at all. A physical SIM is the only route.
• Your phone might be carrier-locked. A lock blocks both routes, but counter staff can check the handset in front of you rather than leaving you to find out after paying online.
• You want to talk to someone. If an eSIM QR code fails to install, you are troubleshooting alone in a foreign airport. A staffed counter puts a person in front of you.
• You did not plan ahead. An eSIM ordered online needs a working internet connection to install. Airport WiFi usually covers that, but if it does not, the vending machine does not care.
• You are staying for months. The 50GB/90-day and 30GB/60-day tiers are priced well per gigabyte compared with repeatedly renewing a short eSIM plan.

What can go wrong with each option?

With the airport counter, the main risks are opening hours and inflexibility. Published hours at Haneda mostly stop between 22:00 and 24:00, so a late arrival may find nothing open in their terminal. SoftBank Global Rental also states that top-up is unavailable on these prepaid SIMs, so if you underestimate your usage you buy a second card rather than adding data.

With an online eSIM, the risks are compatibility and installation. Check your handset supports eSIM and is unlocked before you pay, install the profile over WiFi at home rather than waiting until you land, and confirm whether the plan’s validity starts at purchase or on arrival — Ubigi’s Smartstart plans begin on arrival, but not every provider works that way.

Both routes share one limitation: the plans compared here are data-only, with no Japanese phone number and no SMS. If a hotel, restaurant reservation system or rental service needs to call or text you, neither of these products gives you a number to receive it on.

How to decide before you fly

Work through this in order. Does your phone support eSIM, and is it unlocked? If either answer is no, plan for a counter or vending machine and check your arrival terminal’s published hours against your landing time.

If both answers are yes, estimate your data. Under roughly 10GB for a two-week trip and a fixed-data eSIM such as Ubigi’s 10GB/30-day plan is the cheapest of the options listed here as of August 2026. If you expect to tether a laptop or stream, price an unlimited plan and read its fair-use threshold before buying.

Then, whichever you choose, have a fallback. Knowing that Haneda Terminal 3 has staffed counters from 06:00 and Terminal 1 has a vending machine from 05:00 is useful information to carry even if you never need it.

Frequently asked questions

Is it cheaper to buy a SIM at Narita or Haneda, or online?
Online is cheaper on the published prices for short and medium trips as of August 2026. A 10GB/30-day airport-channel SIM is ¥6,600 including tax, against US$16.50 (about ¥2,600) for Ubigi’s equivalent eSIM. For 90-day, high-volume plans the airport card is more competitive per gigabyte.

Can I buy a SIM at Narita or Haneda after midnight?
It depends on the terminal. Haneda’s published listings show most staffed counters closing between 22:00 and 23:00, with the Terminal 1 AnyFone vending machine running to 24:00 and Mobal’s Terminal 3 collection point listed as 04:00–01:00. Check your own terminal against your scheduled landing time.

Do airport SIMs in Japan include a phone number?
Not the tourist prepaid products compared here. SoftBank Global Rental describes its prepaid SIMs as data service only, with no calling or SMS. The eSIM plans listed above are also data-only.

Do I have to set anything up manually on an airport SIM?
Often yes. SoftBank Global Rental publishes the APN details for its prepaid SIMs as “APN: plus.4g | User name: plus | Password: 4g | Authentication Type: CHAP”. If data does not start flowing once the card is inserted, entering those settings by hand is the usual first step. Requirements and settings differ by seller, so keep the packaging until you are online.

Can I add more data to an airport SIM if I run out?
Not on the SoftBank Global Rental prepaid SIMs — that page states data top-up is unavailable. If you think you might run out, either size up at purchase or choose an eSIM provider whose plans can be topped up or re-purchased in-app.

Should I buy before or after I land?
If your phone is eSIM-capable and unlocked, buying before you fly is generally cheaper on published prices and lets you install the profile on home WiFi. If there is any doubt about compatibility, arriving without a plan and using a counter is a reasonable trade for the higher price.
