Renting a pocket WiFi in Japan takes about ten minutes once you know the routine: book online at least a day ahead, pick the router up at an airport counter or your hotel, and drop it in a return box before you fly home. The parts that catch people out are counter hours, the daily fair-use limits on "unlimited" plans, and the damage fees.
The short version: book online (not at the counter) and choose a daily data tier that fits how you travel. At NINJA WiFi, one of the biggest rental firms, Softbank plans run from ¥440 a day for 1 GB/day to ¥2,200 a day for 5G unlimited. Pick it up at the arrivals counter, return it at the airport counter or after-hours return box before security, and expect to pay about ¥40,000 if you lose it.
Traveling solo with an eSIM-capable phone? An eSIM is usually cheaper and there's nothing to return. A pocket WiFi makes the most sense for families or groups who stay together, or for phones that can't take an eSIM.

How much pocket WiFi rental costs in Japan
Prices are per day, and days are counted inclusively: pick up on Thursday, return on Monday, and you pay for five days. These are NINJA WiFi's own published Softbank pocket WiFi rates, tax included, as of late October 2026.
| Plan | Per day | 7 days | Good for |
|---|---|---|---|
| 1 GB per day | ¥440 | ¥3,080 | Maps, messaging, light browsing for one or two people |
| 3 GB per day | ¥770 | ¥5,390 | A couple posting photos and using maps all day |
| 5 GB per day | ¥1,100 | ¥7,700 | A family of three or four sharing one device |
| 10 GB per day | ¥1,320 | ¥9,240 | Groups, video calls, some streaming |
| Infinite unlimited (Softbank) | ¥1,980 | ¥13,860 | Laptop work |
| 5G unlimited | ¥2,200 | ¥15,400 | Heavy users who want 5G speeds where available |
Extras such as insurance, power banks and delivery cost more and vary by company, so add them up at checkout. Klook sells the same NINJA WiFi router, bundled with a free power bank and sometimes with a discount; at the time of checking, the lowest tier was listed at under US$2 a day.

Not sure which tier you need? Most visitors use well under 1 GB a day per phone. Our Japan data guide breaks it down by activity.
Best pocket WiFi in Japan (2026): NINJA WiFi vs Japan Wireless vs Mobal
Three names come up most when people search for pocket WiFi in Japan, and they work in different ways. Two are classic rentals you hand back; Mobal sells you the router and bills a monthly plan. Here's how they compare, using each company's own site (checked November 1, 2026):
| Provider | How you pay | Data | Pickup | Return |
|---|---|---|---|---|
| NINJA WiFi | Daily rental, ¥440–2,200 a day | 1 GB/day up to 5G unlimited | Counters at 9+ airports, hotel delivery | Airport counter or return box (before security), courier |
| Japan Wireless | Daily rental, from about US$4.7 a day ("The ONE Plan") | Unlimited, no stated speed throttling; up to 8 devices | Narita, Haneda, Kansai, Chubu, Fukuoka, New Chitose; hotel delivery | Prepaid envelope into any Japanese postbox |
| Mobal | Buy the router (¥6,980), then ¥4,980–6,980 a month | 100, 200 or 300 GB a month, then 384 kbps | Narita or Haneda pickup, or home delivery in Japan | Nothing to return: you keep it and cancel the plan |
- Short trip, want to pick the cheapest tier: NINJA WiFi. The 1 GB and 3 GB plans undercut flat-rate unlimited rentals, and Klook sells the same router with a power bank. Check NINJA WiFi’s 1 GB and 3 GB plans on Klook (opens in a new tab).
- Heavy users who hate data limits: Japan Wireless's single unlimited plan is the simplest choice, and the postbox return means no airport detour on your last day.
- Long stays or repeat visits: Mobal. Paying ¥6,980 for the router only makes sense if you'll use it for a month or more, or come back to Japan; for a one-week trip a rental is cheaper.
Booking: how far ahead and what you'll be asked
Book online. NINJA WiFi's online form takes applications up to one day in advance, and most of its airport counters accept bookings up to the pickup day itself. A few have earlier cutoffs:
- Narita Terminal 1: book by 4:00 p.m. Japan time the day before pickup.
- New Chitose domestic terminal: three days before, by 4:00 p.m.
- Asahikawa: four days before. Komatsu: two days before.
You'll be asked for your flight number and which airport you want to pick up from and return to. They can be different airports, which helps on a Tokyo-in, Osaka-out trip. If two of you each want a router, that's two separate bookings.
Airport pickup counters and hours
Counter hours matter more than anything else here. If your flight lands at 10:30 p.m. and the counter closed at 9:30, you'll start your trip offline. These are NINJA WiFi's pickup hours at the main international airports:
| Airport | Pickup hours | Return |
|---|---|---|
| Haneda Terminal 3 (international) | 6:30 a.m.–11:45 p.m. | Return box from 11:45 p.m. to 6:30 a.m. |
| Narita Terminal 1 | 6:30 a.m.–9:30 p.m. | Counter 7:00 a.m.–9:00 p.m. |
| Narita Terminals 2 and 3 | 7:00 a.m.–9:00 p.m. | Counter |
| Kansai Terminal 1 | 6:00 a.m.–11:00 p.m. | Counter |
| Kansai Terminal 2 | 7:00 a.m.–9:30 p.m. | Counter |
| Chubu Centrair Terminal 1 | 6:30 a.m.–10:00 p.m. | Counter |
| New Chitose (international) | 8:00 a.m.–7:00 p.m. | Counter |
| Fukuoka | 7:00 a.m.–9:30 p.m. | Counter |
| Naha | 7:30 a.m.–9:00 p.m. | Counter |
Bring your voucher plus your passport or photo ID. Landing late? Choose hotel delivery instead and the router will be waiting at check-in. Once you have it, test it right away, before you buy a train ticket into the city (our Narita and Haneda to Tokyo guide covers that next step).
Book pocket WiFi with airport pickup on Klook (opens in a new tab)How to return a pocket WiFi in Japan
You have three options, depending on the company:
- Airport counter on your departure day, if it's open.
- Airport return box, usually next to the counter, for early or late flights.
- By post or courier from your hotel. NINJA WiFi offers courier return, and some companies (Japan Wireless, for one) include a prepaid envelope you can drop in any red postbox.
One rule people miss: NINJA WiFi's counters and boxes are all before the security gates, so drop the router off before you go through. Pack the cables and pouch with it, because each has its own fee if lost (Klook's NINJA WiFi listing shows ¥500 for the USB cable and ¥1,000 each for the pouch and charging cable).
What "unlimited" really means
Read the fine print. NINJA WiFi's 3 GB and 10 GB daily plans slow down, or may briefly drop out, once you pass the day's allowance. Even unlimited plans fall under the carrier's fair usage policy, so streaming lots of video or downloading big files in a short time can get you throttled without warning. For a laptop-heavy trip, pick the top tier and keep your big downloads for hotel WiFi.
Battery is the other limit. A router that runs flat at 4 p.m. takes everyone in your group offline with it. That's why the free power bank in the Klook bundle is worth having.
Pocket WiFi or eSIM: which costs less?
Compare the whole trip, not the daily rate. Airalo's Japan unlimited eSIM was listed at ¥4,300 for 7 days on the day we checked, per phone. So:
- Solo: one eSIM (about ¥4,300) vs. a 3 GB/day router (¥5,390). The eSIM wins, and there's nothing to carry, charge or return.
- Couple: two eSIMs (about ¥8,600) vs. one router (¥5,390–7,700). The router is cheaper if you stay together all day.
- Family of four: four eSIMs (about ¥17,200) vs. one 5 GB/day router (¥7,700). The router wins clearly.
If your phone supports eSIM and you'll split up during the day, check Airalo's Japan eSIM prices (opens in a new tab) or Saily's Japan plans (opens in a new tab) first. Our eSIM vs pocket WiFi comparison goes through the trade-offs in more detail.
Questions about renting pocket WiFi in Japan
Do I need a deposit?
Not usually for online bookings in Japan. NINJA WiFi takes payment by credit card when you apply, and Klook's Softbank router listing says no deposit is needed. Loss or damage is charged afterwards: Klook's NINJA WiFi listing shows ¥40,000 for the router itself.
Can I return the router at a different airport?
Yes. You choose the pickup and return locations at booking, so you can land at Narita and fly out of Kansai.
What if I forget to return it and leave Japan?
Contact the rental company right away. Late returns usually cost extra (Japan Wireless, for example, charges ¥1,100 per late day), and each company has its own procedure for mailing it back from abroad. NINJA WiFi has an FAQ entry on exactly this.
How many devices can connect?
It depends on the model: roughly 5 to 14. A Docomo router sold on Klook allows up to 5 devices, while a Softbank one allows up to 14. Whatever the number, everyone shares the same daily data allowance.
Our take for a 2026 trip
For groups and families, a mid-tier pocket WiFi booked online with airport pickup is the cheapest way to keep everyone connected. Check your arrival time against the counter hours, add the power bank, and return it before security. Traveling alone or with a newer phone? Skip the router and go with an eSIM.
