If you accidentally took your Japan Wireless pocket WiFi home, ship it back to the Japan Wireless Delivery Center in Shimbashi, Tokyo using a traceable international courier (EMS, FedEx, or DHL) and declare the invoice value as ¥5,000 or less. Late return fees accrue at ¥1,100/day after the grace period (verify), so send the package as soon as you notice.
Return Shipping Address
Ship the device, cable, and case to the address below. Write your order number (starts with “A”) next to the recipient name so the warehouse can match your return to your account.
Japan-Wireless Delivery Center (Axxxxx ← your order number)
5F, SW Shimbashi Building
6-14-5 Shimbashi, Minato-ku
Tokyo 105-0004, Japan
Tel: +81-70-6487-2924
After you drop off the package, email Japan Wireless the courier name and tracking number so support can flag the incoming shipment and stop the daily late fee from accruing.
What to Include (and What to Leave Out) in WiFi Package
| Item | Return? | Reason |
|---|---|---|
| Pocket WiFi router | Yes | Main rental item |
| USB charging cable | Yes | Part of kit |
| Carrying pouch / case | Yes | Part of kit |
| Extra mobile battery (power bank) | No | Lithium batteries banned on international air freight |
| Prepaid Japan Post return envelope | No | Only works inside Japan |
The extra power bank cannot be shipped internationally because of IATA lithium-battery air-freight restrictions. Remove it from the package before you hand it to the courier. Japan Wireless will bill the unreturned power bank as a separate item on your card.
Courier Comparison for International Return
Use a traceable service. Untracked airmail is not accepted because Japan Wireless cannot confirm delivery to Shimbashi.
| Courier | Traceable? | Typical transit to Tokyo | Notes |
|---|---|---|---|
| EMS (postal express) | Yes | 3–7 days | Cheapest for most countries; declare ¥5,000 or less |
| FedEx International | Yes | 2–4 days | Fastest; higher cost |
| DHL Express | Yes | 2–4 days | Fastest; higher cost |
| Untracked airmail | No | N/A | Not accepted — no proof of delivery |
Declaring the value as ¥5,000 or less on the customs form keeps the package under Japan’s simplified import threshold and avoids import duty charges that would otherwise be billed back to Japan Wireless (and passed on to you).
If You Are Still in Japan
If you have not yet flown home, do not international-ship. Instead:
- Drop the prepaid Japan Post envelope in any street postbox, convenience-store mailbox, or airport post box before departure.
- Airport return boxes are available at Narita T1 (4F Departure Lobby), Narita T2 (3F Departure Lobby, near C/D check-in), Haneda T3 (3F Departure Lobby between E and F counters), Kansai T1 (4F Departure Lobby), and Chubu / New Chitose (3F/2F Departure Lobby near information desk).
- The prepaid envelope covers domestic postage — no stamp needed.

Frequently Asked Questions
I forgot to return my pocket WiFi and I’m already home. What do I do?
Ship the device back to the Japan Wireless Delivery Center at 5F SW Shimbashi Building, 6-14-5 Shimbashi, Minato-ku, Tokyo 105-0004 using EMS, FedEx, or DHL. Declare the invoice value as ¥5,000 or less on the customs form. Write your order number (starts with A) on the label, then email Japan Wireless the tracking number so they can stop the daily late fee.
How do I return a Japan Wireless pocket WiFi from Japan?
Drop the prepaid Japan Post return envelope in any Japan Post mailbox, convenience-store post box, or airport return box before you fly home. The envelope comes inside the rental kit and postage is prepaid. Airport return boxes are located at Narita T1/T2/T3, Haneda T3, Kansai T1, Chubu, and New Chitose — all in the Departure Lobby areas.
Can I return the extra power bank by international shipping?
No — lithium-battery power banks are prohibited on international air freight under IATA rules. Remove the extra battery from the package before handing it to EMS, FedEx, or DHL. Because the power bank cannot be returned once it leaves Japan, Japan Wireless will bill it as a separate charge on your card.
What’s the late fee if I return my pocket WiFi late?
Late returns are charged ¥1,100 per day after the grace period (verify current rate at checkout). The clock stops once Japan Wireless receives the package, so use a fast, traceable courier (FedEx or DHL, 2–4 days) rather than surface mail. Sending the tracking number by email lets support pause the fee at the delivery date rather than the receipt-into-warehouse date.
What value should I declare on the customs form?
Declare the total invoice value as ¥5,000 (approximately US$33) or less. This keeps the shipment under Japan’s simplified import threshold and avoids import duty and consumption tax that would otherwise be charged on arrival. Marking the package as “returned rental equipment” also helps customs clear it without delay.
What if I lost the prepaid return envelope while still in Japan?
Take the device to any Japan Post office counter and ship it as a domestic parcel (Yu-Pack, from ¥800) to the Shimbashi address above. Alternatively, drop it in an airport return box before departure — Narita T1 (4F), Haneda T3 (3F between E/F counters), and Kansai T1 (4F) all have staffed return points during Departure Lobby operating hours.
Do I need to email Japan Wireless after I ship the return?
Yes — send the courier name and tracking number to Japan Wireless support after handing over the package. This lets the team match the incoming parcel to your order (Axxxxx number), confirm the ship date for late-fee purposes, and reach out if the shipment is delayed in customs. Support is available 24 hours in English, Japanese, Chinese, and Korean.
