Japan Pocket Wifi Rental
Japan eSIM : Fast & Easy & UNLIMTED
Japan Travel eSIM
Before you fly · Narita · Haneda · Kansai · Fukuoka · Centrair
You clear immigration, collect your bag, and walk out into the arrivals hall with a dead map app and a hotel address you can’t pronounce. Getting online is the first thing you’ll do in Japan — and the arrivals hall is the most expensive place to do it.
Every major Japanese airport sells you a way onto the network: staffed rental counters, SIM vending machines that run when the counters have closed, and a hold-for-collection service that lets you order online weeks earlier at online prices. They cost wildly different amounts, they keep wildly different hours, and the collection points have quietly moved in the last few years — most guides still send you to a post office that shut in 2021.
There are four ways to get online once you land, and this guide covers all of them at Japan’s main gateways — Narita (NRT), Haneda (HND), Kansai (KIX), Fukuoka (FUK) and Chubu Centrair (NGO), with New Chitose and Itami in the pickup table too — along with the arrival-time and terminal traps that catch people out.

How you can actually get online at a Japanese airport
There are only four realistic options, and they sort themselves cleanly by price, speed, and how forgiving they are if your flight lands late. Pick the row that matches your arrival, not the one that looks easiest on a map.
Staffed desks in the arrivals lobby. Someone hands you the device and shows you how it works. Stock is limited and walk-up rates are the highest you’ll pay anywhere.
Fastest, priciest
Data-only prepaid SIMs from a machine, available when the counters are shut. No staff, no setup help, and no refund if the card doesn’t work in your phone.
Late arrivals only
Order online weeks ahead at online prices and have the package waiting for you when you land — at the airport post office, or at a partner counter where there’s no post office. No holding fee, no queue, and the package is held for days if you’re late.
Cheapest, most flexible
Bought and installed before you leave home, activated when you land. Nothing to collect, nothing to return, no counter hours to beat.
No pickup required
Your landing time decides most of this. At Narita, Haneda and Centrair, an evening arrival closes off Routes A and C and leaves you choosing between a vending machine and something you set up before departure. At Kansai and Fukuoka the collection counter runs until 21:00 every day, which changes the answer completely — see the table further down.
Book before you fly and the arrivals hall stops mattering
Almost everything that goes wrong with airport connectivity goes wrong because someone decided to sort it out on landing. Book ahead and you get three things at once: a lower price, a guaranteed device, and a free choice of where to collect it.
The price gap is consistent and large. Online rates for the same class of device sit well below walk-up counter rates — plans start from under ¥200 per day for basic allowances, while walk-up rates for comparable unlimited devices have historically sat in the ¥1,200–¥1,600 per day range. At the counter you’re paying a premium for the fact that you didn’t book.
Availability is the other half. Counters hold limited stock and do sell out, and several providers don’t accept walk-ups at all. Reserving turns a gamble into a collection. Good providers also guarantee the package arrives at your chosen address the night before your rental period starts, so it’s genuinely waiting for you rather than in transit.
Late March and April (cherry blossom), October and November (autumn leaves), and late December all run tight. During these months even advance bookings can hit their quota. If you’re travelling then, reserve as soon as your flights are confirmed rather than the week before.
Rental counters: what you’re paying the premium for
The case for a counter is genuinely good in one situation: you want a human being to put the device in your hand, confirm it’s charged, explain the return method, and sort it out on the spot if something’s wrong. If that matters to you, book a counter provider and stop reading this section.
Narita, Haneda, Kansai and Centrair all host counters from the major rental brands — SoftBank Global Rental, Telecom Square (Wi-Ho!), JAL ABC, Ninja WiFi/Global WiFi, XCom Global and others — typically in the arrivals lobby or on the access-plaza level. Narita has additionally offered a shared pickup desk serving several brands that don’t run their own counter.
Two things to check before you rely on one:
Most counters shut somewhere between 20:00 and 22:30. Add immigration, baggage and customs to your scheduled arrival — on a bad day that’s well over an hour — before assuming you’ll make it.
Several brands staff one wing but not the other, and at some airports the counter sits landside on a different floor from where you exit. Your confirmation email names the exact desk; screenshot it before you board.
Counter hours, desk names and floor locations change more often than any other detail in this guide. Treat the location in your booking confirmation as authoritative and this article as orientation.
SIM vending machines and the late-night arrival
Prepaid SIM vending machines exist at Narita and in Haneda’s Terminal 3, usually in the arrivals area and near the train station concourses. They’re the reason a 23:40 landing isn’t a disaster. They are not, however, a good deal, and there are four things nobody tells you at the machine:
Some take cash only, some card only. Carry both. Our guide to how much cash to bring to Japan covers what else you’ll want yen for on day one.
Especially the cheaper short-validity cards, and especially in peak season. A machine at the airport is not a guarantee of stock.
No phone number, no SMS. If you need SMS to receive verification codes, a vending machine can’t help you.
Not if your phone turns out to be carrier-locked, not if you bought the wrong size, not if the APN never connects. You are alone with a ¥5,000 piece of plastic and no counter open to complain to.
That last point is the real cost. Check your handset is unlocked and compatible before you fly — see our checks for iPhone and Android devices.
Hold-for-collection: the route most travellers miss
This is the option nobody mentions, and it’s the one that saves the most money. Japan Post runs a service called kyoku-dome (局留め) — “hold at post office.” A rental company posts your device to a named post office, the post office keeps it for you, and you collect it with photo ID. There is no additional fee for the holding service itself, beyond the normal cost of shipping.
Because it removes the cost of staffing an arrivals hall, providers using this route price well below the counter brands. CDJapan Rental, our affiliated provider, works this way: no counter of its own and no vending machines, so the saving goes into the rate instead. Packages go to airport post offices, any post office in Japan, hotels, schools and dormitories, and residential addresses. At the two big airports with no post office — Kansai and Fukuoka — collection happens at a partner counter, which as you’ll see below is the most forgiving option in the country. Full conditions are on the receive & return page.
A post office holds your package for three to five days. If your flight is delayed, or you simply can’t face one more errand before the hotel, you can collect it the next day instead. This is the single biggest misconception about the route: it is not a same-hour appointment you either make or miss.
How to collect it
Do this well in advance. Reputable providers guarantee delivery the night before your rental period starts, so the package is waiting when you land.
Airport post offices are landside, outside the gates. You cannot reach one before you’ve formally entered the country. If you’re still doing paperwork at this stage, our Visit Japan Web guide will speed up the immigration half.
Post offices are split between Japan Post Bank (Yucho) services and postal services. You want the postal side; at larger branches this is the Yu-Yu window (ゆうゆう窓口), which stays open longer than the standard counter. At a partner pickup counter there’s only one desk, so this doesn’t apply.
Photo ID is mandatory. The name on it must match the recipient name exactly — middle names and second surnames included. Have the tracking number from your confirmation email ready; searching by a romanised name is slow and error-prone.
Where you can actually collect, airport by airport
This is where most guides are badly out of date, so read the table before you plan around it. Not every airport has a post office, the two busiest that don’t have a partner counter instead, and the opening hours vary by five and a half hours from best to worst.
| Airport | Collection point | Where | Hours | Open |
|---|---|---|---|---|
| Kansai (KIX) | Sakura Mobile counter (not a post office) | Terminal 1, 1F | 7:00–21:00 | Every day |
| Fukuoka (FUK) | Sakura Mobile counter (not a post office) | International Terminal, 1F | 7:00–21:00 | Every day |
| Narita (NRT) | Post office, Terminal 1 branch | Terminal 1, 4F departure lobby | 8:30–20:00 | Every day |
| Narita (NRT) | Post office, Terminal 2 branch | Terminal 2, 3F departure lobby | 8:30–20:00 | Every day |
| Narita (NRT) | Terminal 3 — none | Use the Terminal 2 post office | — | No post office |
| New Chitose (CTS) | Post office | 2F arrivals lobby | 9:00–17:00 | Every day |
| Itami / Osaka (ITM) | Post office | Central terminal, 1F | 9:00–17:00 | Every day |
| Haneda (HND) | Post office | Terminal 1, 1F — not Terminal 3 | 9:00–17:00 | Weekdays only |
| Chubu Centrair (NGO) | Post office | Terminal 1, 1F | 9:00–17:00 | Weekdays only |
Neither has a post office — the Kansai airport branch closed permanently in March 2021 and Fukuoka has never had one — so CDJapan Rental sends packages to a dedicated Sakura Mobile counter instead. It’s open 7:00 to 21:00, every day of the year, which is longer than any airport post office in the country. Collection works exactly the same way: give the staff your tracking number or order number, show your passport, done.
Older guides that tell you Kansai has an airport post office are five years out of date. The counter is the answer now, and it’s a better one.
Almost all international flights arrive at Haneda Terminal 3, and the post office is in Terminal 1 — a free connecting bus away — open weekdays only, 9:00 to 17:00. For a weekend arrival at T3, send the package to your hotel or a post office in the city instead; it is the same price. Narita Terminal 3 has a milder version of the same thing: no post office of its own, but the free inter-terminal bus reaches the Terminal 2 branch in about five minutes.
You are not tied to the airport
The airport is only one of the addresses on offer, and often not the best one. If your flight lands late, if you’re arriving on a weekend at Haneda or Centrair, or if you’d simply rather walk straight to the train, pick a different collection point — it costs nothing extra and you keep the online price.
Delivered before check-in and handed over at the front desk. The recipient name must match your booking name exactly, and it’s worth telling the hotel a package is coming.
Same kyoku-dome process, no fee, and you choose the branch. Some Japanese post offices run 24 hours — see our list of 24-hour post offices in Japan, which is the cleanest answer to a midnight landing. Arriving into Kansai and staying in the city? Poste restante pickup points around Osaka covers the branches near major stations.
Posted straight into the mailbox, so nobody has to wait in. Short-stay rentals are the awkward case: the address has to be registered with the post office and the recipient name has to match a resident, so a nearby post office is usually the safer pick. Our guide to receiving mail at an Airbnb address explains what goes wrong.
The step-by-step of collecting from a counter, including the Japanese phrase to show if the staff don’t speak English, is in our guide to receiving mail at a post office in Japan.
Address changes are free up to five days before your rental start date. After the package has shipped, providers can usually redirect it — CDJapan Rental forwards to your hotel for a ¥1,000 fee. Email as soon as you know. And remember the package sits at the post office for three to five days anyway, so a delay of a few hours changes nothing at all.
Pocket WiFi, SIM, or eSIM?
The pickup logistics above are usually what decides this, but the devices themselves differ in ways worth knowing. In short: pocket WiFi suits groups and laptop users, a SIM or eSIM suits solo travellers who want to carry nothing extra.
| Pocket WiFi | Physical SIM | eSIM | |
|---|---|---|---|
| Shares with others | Yes — several devices at once | No | No |
| Extra thing to carry | Yes, plus a charger | No | No |
| Keeps your home number | Yes | No — you swap the card out | Yes, runs alongside it |
| Must be returned | Yes | Rentals yes, prepaid no | No |
| If you lose it | Penalty, often ¥10,000+ | Minor | Nothing to lose |
| Available on arrival day | Counter or post office hours | Counter, vending machine or post office | Anytime — set up before you fly |
Battery life is the practical catch with pocket WiFi: it’s a second device to keep charged, and a flat router takes the whole group offline. For a fuller side-by-side, including data allowances and speed throttling, see Pocket WiFi vs eSIM: internet access in Japan, and check the fair usage policy on anything sold as unlimited.
An eSIM sidesteps every hours-of-operation problem on this page: you install it before you leave home, and it’s live the moment your plane touches down — no counter to find, no post office to beat, nothing to return on the way out. CDJapan Rental’s eSIM runs on the docomo network for coverage across the country, and setup is a QR scan with no SIM swap.
What Japanese prepaid SIMs can and can’t do
Japan’s telecoms rules are stricter than most visitors expect, and they shape what’s on sale at the airport. Two limits catch people out.
Almost nothing comes with a phone number
Voice-capable service in Japan is generally restricted to residents with verifiable visa status and a registered address — a crime-prevention measure. The practical result is that visitor prepaid SIMs are data-only. A handful of products add SMS capability, which is what you actually need if you’re trying to receive verification codes to sign up for services; true voice SIMs for short-term visitors are rare and never sold from a machine.
Validity tops out at about 30 days
Prepaid cards come in 7, 8, 10, 15, 16 and 30-day denominations, and you’ll struggle to find anything longer. For a stay of more than a month, a rental SIM or a monthly plan is both cheaper and simpler than chaining prepaid cards together.
Prepaid SIMs sold at airport counters and vending machines have run roughly ¥2,800–¥7,000 depending on data allowance and validity, with unlimited multi-week cards at the top of that range. The same money buys considerably more data ordered online in advance. Prices move — check current rates before you commit.
Electronics chains are the middle option worth knowing about: Bic Camera and Yodobashi Camera stock visitor SIMs, and unlike a vending machine there’s multilingual staff who will check your handset is unlocked and set the APN before you walk out. If you’d rather not gamble at the terminal, that’s the safer place to buy after arrival. Already bought an eSIM? Read what to know after purchasing your eSIM for Japan before you land.
Returning your device
Rentals need to go back, and this is where the post-office route pays off again. Most online providers include a prepaid return envelope: you drop it in any Japanese postbox on your way out, and you’re done. Counter-based providers usually want the device handed back at a counter, sometimes with a return box available outside opening hours.
Airports have designated postboxes near the departure floors for exactly this. We’ve mapped them at Narita, Haneda, Kansai, Fukuoka, New Chitose, Chubu and Naha in our guide to WiFi return postbox locations at major Japanese airports. Post the envelope before you go through security — there are no postboxes airside.
Prepaid SIMs and eSIMs have nothing to return. If your departure day is tight, that’s a real advantage over a rented router you have to remember to post.
Frequently asked questions
Is it cheaper to book pocket WiFi online or at the airport counter?
Online, consistently. Walk-up counter rates include a premium for same-day availability and staffed service. Online plans for comparable devices start from under ¥200 per day for basic allowances, while counter rates for unlimited devices have sat in the ¥1,200–¥1,600 per day range. Booking ahead also protects you against stock running out in peak season.
Can I have a pocket WiFi or SIM held at the airport post office?
Yes, using Japan Post’s kyoku-dome hold service, and there’s no extra fee for the holding itself. Airport post offices that can hold a package include Narita Terminals 1 and 2 (8:30–20:00 daily), New Chitose and Itami (9:00–17:00 daily), and Haneda Terminal 1 and Chubu Centrair (9:00–17:00, weekdays only). Kansai and Fukuoka have no airport post office, but CDJapan Rental delivers to a Sakura Mobile counter at both, open 7:00–21:00 every day. Bring your passport — the name must match the recipient name exactly — and have the tracking number ready.
What if I land after the counters and post office have closed?
Less than you think. Post offices hold a package for three to five days, so a late landing usually just means collecting it the next morning rather than losing it. At Kansai and Fukuoka the Sakura Mobile counter runs until 21:00 daily, which covers most evening arrivals outright. If you would rather not detour at all, send the package to your hotel or to a post office near your accommodation instead — same price — and use an eSIM for the ride into the city.
Can I get a Japanese prepaid SIM with a phone number?
Effectively no. Japanese regulations restrict voice service to residents with verifiable visa status and address, so visitor prepaid SIMs are data-only. Some products include SMS capability, which is what you need for receiving verification codes; these are worth seeking out if you plan to register for Japanese services. Nothing sold from a vending machine includes SMS.
Where do I return a rented device when I fly home?
Most online providers supply a prepaid return envelope you can drop in any postbox in Japan, including the designated postboxes on the departure floors at major airports. Counter-based providers generally want the device returned to a counter, though many offer a 24-hour return box. Post it landside — there are no postboxes after security.
Collection points and hours verified against Japan Post, airport operator information and CDJapan Rental’s published pickup list. Rental counter locations, opening hours and prices change frequently — always confirm against your booking confirmation and the provider’s website before you travel.
