You need to make a reservation 3days in advance. Make your request by 3 pm (JSTJapan Standard Time, No daylight saving), at least 3 days prior to your desired rental period.
Please be careful about the time difference between Japan and your country. Generally speaking, Japan is ahead of your country. Don’t forget this point.

Same day delivery service

They support the same-day service, but you need to keep in mind the limited time.

For urgent same-day rental, you need to make a request by 2 pm for same-day rental.
For example, in the case you are a New Yorker:
You need to make a reservation by midnight of the previous day.
You need to make a reservation by 1 am on the same day (during the period when daylight saving time is applied).

For example, in the case you are an English person:
You need to make a reservation by 5 am on the same day.
You need to make a reservation by 6 am on the previous day (during the period when daylight saving time is applied).

Pick up and return a Wifi router

  • Currently Narita International Airport counter is closed because of COVID-19.

When you are going back to your country, you put the set of Wi-Fi routers into the supplied envelop and mail it.

Mail Posts are everywhere, so it’s very convenient. Also, there are some posts at an International Airport.
One important thing to remember is that there are no posts after passport control at each airport, so you’d better remember where the post are well in advance and don’t forget to mail the rent router into a post before you go through passport control.

About cancellation

They accept cancellation by email.
The Cancellations made four or more days prior to your rental period will be free of charge.
If you miss canceling the reservation, you will be charged 3,000 JPY as a cancellation fee.
A reminder again is the time difference between Japan and your country.
Four days means almost five days for many people.


They don’t have any insurance.

The company believe that your traveller’s insurance covers compensation fees.
You need to check your insurance agency/company how wide the insurance covers.


You may exceed 1GB/day (2GB/day), they will make a capping of 200kbps.
It seems 4G LTE becomes 3G slowness.

Number of devices be connected to one wifi router

The company recommends 1 to 2 devices for each pocket WiFi unit.
