Pocket WiFi rentals, SIM cards and eSIMs for travel in Japan.

Savings opportunities available through NINJA WiFi coupon codes

NINJA WiFi offers portable internet for visitors to Japan through Pocket WiFi rentals, SIM cards and eSIMs. Rental savings start with matching the daily data allowance to your trip: Unlimited Plan (1GB per day) is 440 yen/day including tax. Sharing a router lets several people split the rental expense. Airport counter collection and return are free, while delivery pickup and return each add 550 yen for up to four units. The offers on this page fit alongside these booking choices, with any accepted reduction listed separately from rental and optional service fees.

Eligible products and services

Service categories frequently on promotion

The WiFi booking form provides single-device and two-device selections with different daily rates. Unlimited Plan (3GB per day) is 770 yen/day, Unlimited Plan (5GB per day) is 1,100 yen/day, and Unlimited Plan (10GB per day) is 1,320 yen/day for a single device. Infinite Unlimited Plan is 1,980 yen/day, while 5G Unlimited Plan is 2,200 yen/day. These amounts include tax. Dates, quantities, pickup and return methods, insurance and accessories build the service selection before the coupon entry. The summary then separates the rental charge from additional services and the discount.

Services usually excluded from promo codes

Optional services are separate charges in the rental order. Full Insurance Plan adds 330 yen/day, Mini Insurance Plan adds 220 yen/day, and Plug Adapter adds 110 yen/day, with tax included. Delivery has its own pickup and return charge rather than being part of the router rate. Cancellation Protection is another selectable expense, calculated at 10% of the order amount excluding tax. For a protected cancellation, the refund excludes that protection fee. Bookings containing Airport Transfer Service or Luggage Delivery Service are ineligible for the usage-fee refund under Cancellation Protection.

Factors influencing the final discount value

Impact of billing cycle on promotional price

NINJA WiFi calculates rental charges by the day for the travel period entered in the application. Each booked day incurs a usage charge even when the router is not used. A longer stay therefore extends the rental period shown in the order rather than choosing an annual subscription. Extensions requested with at least one day's notice use the listed daily rental and option rates. Without advance contact, an additional 1,617 yen/day applies; plans above that daily rate retain their contracted rental and optional fees for excess days. Charges continue until equipment return is confirmed.

Promo codes vs. automatically applied offers

A typed offer goes into the Coupon code field during Service Selection. The form lists Discount as a separate adjustment alongside the charges selected for the reservation. Built-in booking choices also affect the starting amount: the two-device Unlimited Plan (1GB per day) has a listed rate of 792 yen/day including tax, while a single device is 440 yen/day. Airport counter handling is free; delivery is separately billed. These selectable rates and handling charges establish the order amount before its discount, subtotal, tax and final total are reviewed for payment.

Accessing active codes for NINJA WiFi

Start with Select Dates, then Select Your Data Plan and the number of devices. The Select Pick-up/Return Locations and Select Insurance sections come before the optional services. The Coupon code section follows those options, with the instruction "Please enter your coupon code below" and an input labelled "Coupon". Cancellation Protection appears underneath. The expandable Details summary separates WiFi Router Rental Fees, delivery and Optional Service Fees from Discount, Subtotal, Tax and Grand Total. Service Selection precedes Customer Information and Payment, so the booking choices and coupon entry belong to the first step. Scroll up for the current NINJA WiFi offers.

NINJA WiFi Discount FAQs

Enter your offer in the Coupon code section of Step 1 Service Selection, and review the Discount line in the order details. Dates and the data plan come earlier in the form, followed by collection and return arrangements, insurance and optional services. The entry box uses the placeholder "Coupon" beneath "Please enter your coupon code below". Cancellation Protection sits after this section, so it remains a separate booking choice. Expanding Details reveals the rental fees, delivery charges, optional fees, subtotal, tax and grand total. Customer Information and Payment follow Service Selection. Completing the rental choices first establishes the charges against which the displayed discount is recorded.
The single-device Unlimited Plan (1GB per day) starts at 440 yen/day including tax before any accepted coupon reduction. Unlimited Plan (3GB per day) is the next allowance option at 770 yen/day including tax. The booking begins with pickup and return dates, and the amount depends on the chosen rental period and device quantity. Insurance and accessories have their own daily charges, while delivery contributes a separate handling fee. The total breakdown distinguishes those selections from the discount and tax calculation. A router can connect multiple people and devices. Choosing the lower data allowance reduces the daily rental component when that allowance suits the trip.
Yes, the reservation form offers a 2 device Plan before the coupon section, with its own daily rental rates. For Unlimited Plan (5GB per day), the two-device selection is 1,870 yen/day including tax, compared with 1,100 yen/day for a single device. Unlimited Plan (1GB per day) lists 792 yen/day for the pair and 440 yen/day for one router. The device quantity and travel dates are part of Service Selection, followed by handling arrangements and optional extras. Those choices contribute to the rental summary, where any coupon adjustment occupies the Discount line. Sharing a single router is also possible when the travelers stay together and connect their devices to it.
Choose airport counter pickup and airport counter return to avoid the separately charged delivery services. Delivery pickup is 550 yen, and delivery return is another 550 yen, including sales tax for up to four units. The reservation lets you select the collection and return locations before reaching the coupon box. You can hand the router back at a different airport counter from the collection point, and return-location changes are made through My Page. Hotel delivery goes to the front desk; accommodation without a desk requires someone to receive the parcel. Airport handling therefore reduces the service charges included in the order while leaving the selected rental allowance and duration intact.
Insurance is selected separately from the data plan, with individually priced protection options in the rental form. Full Insurance Plan is 330 yen/day including tax and covers device damage in full. Mini Insurance Plan is 220 yen/day including tax, while Insurance + Battery Plan adds a spare battery at 440 yen/day including tax. The insurance step comes before accessories and coupon entry, and the summary includes an Optional Service Fees line. You can select No Insurance through the stand-alone insurance choices, with additional fees payable for lost or broken equipment. Selecting the protection level separately keeps its daily charge visible alongside the rental amount and any discount adjustment.
Extra rental days are charged as an extension, and you need to contact NINJA WiFi customer support. With notification at least one day in advance, the extension schedule lists the daily rates for the rented plan and optional services. Extending without contact brings an additional 1,617 yen/day charge for each extra day. When the contracted daily rate exceeds that amount, rental and optional fees continue for the excess days regardless of notification. The service term follows the applied travel period, and extension fees run until the return is confirmed. Additional charges are handled at departure or return. Giving advance notice protects the booking from the stated charge for an unannounced extension.
You can cancel without a cancellation fee when the cancellation is completed at least four days before departure. This timing rule applies whether or not Cancellation Protection was selected, and cancellation is available through My Page. Within three days before departure, the fee without protection is 100% of the application amount; with protection, the protection fee remains payable. The selected option therefore affects the refundable balance near departure. Refund processing runs through the credit card company and can reach the next month or the following month. The card issuer handles specific processing enquiries. Completing cancellation before the free-cancellation deadline preserves the amount that would otherwise be taken as a cancellation fee.
The Cancellation Protection fee is retained, while eligible protected cancellations receive the full usage-fee refund. Protection itself is charged at 10% of the order amount excluding tax and is selected in the reservation form beneath the coupon section. It allows cancellation up to departure day if the trip is cancelled. Customers who booked Airport Transfer Service or Luggage Delivery Service are not eligible for this protection refund. The option cannot be added once the reservation is complete. Cancellation refunds are returned through the card company, with processing potentially reaching a later statement. Including Cancellation Protection during the original booking establishes the protection needed for a qualifying cancellation close to departure.
NINJA WiFi takes credit card payment for the reservation after the service selection and customer information steps. Your application requires an email address and card information, and a confirmation email contains the reservation details. Payment is charged during the website application or through the dedicated card payment screen. The order's Details breakdown separates the discount from rental, delivery, optional services, subtotal and tax before the grand total. Later optional-service charges, extensions, date-change refunds or cancellations are handled at departure or return, which can produce two or three separate card charges. Keeping the reservation number from the confirmation email available helps the customer center identify the booking when a billing issue needs attention.
A defective device, or equipment dirtied or damaged in transit, is replaced through the NINJA WiFi Customer Center. Unopened equipment can be returned within nine days of its original shipping date, with return shipping paid by the customer. For a return caused by a problem attributable to the company, the company bears the shipping expense instead. Communication before such a return incurs a prorated basic charge and applicable transmission fees. Faults in opened equipment are handled by contacting the center about replacement. The reservation number appears in the confirmation email and identifies the rental during the call. Reporting the fault with that number connects the replacement request to the affected booking.
