Frequently Asked Questions (FAQ)

Q. Is a coupon code required to get the NINJA WiFi discount on LIVE JAPAN?
A. No coupon code is required. When you book through the buttons on this exclusive LIVE JAPAN page, the 80% discount (Unlimited Plans) or 35% discount (Fixed Data Plans) is automatically applied to your total in the Service Selection summary. Just click the button and the discount appears without entering any code.

Q. Which data plan should I choose? (Fixed Data vs. Unlimited Plans)
A. We strongly recommend the Unlimited Plans (4G SoftBank & 5G docomo). Google Maps, social media, and video calls use a lot of data. These Unlimited Plans are completely stress-free, and thanks to our exclusive 80% discount, they are even cheaper than some fixed data plans! (The 80% discount applies to both 1-device and 2-device options.)

Q. What is included?
A. You receive a pouch containing the WiFi device, an AC adapter, a USB charging cable, and a user manual.

A. We recommend it. The replacement fee for a lost or broken device can be very high. Insurance gives you peace of mind.


Q. What is the real-world battery life of the pocket WiFi?
A. Typical battery life is 6 to 10 hours depending on usage. For heavy users using Google Maps or streaming, we recommend adding a mobile battery to your rental to ensure a full day of connectivity.

Q. How stable is the connection on the Shinkansen or in rural areas?
A. We use the SoftBank network, covering the majority of Japan's populated areas. Connectivity is highly stable in cities and at Shinkansen stations, though brief interruptions may occur in long tunnels or remote mountain regions.

Q. How fast is the "Smart Pick Up" at the airport?
A. It is incredibly efficient—you can pick up your device in as little as 10 seconds by scanning your QR code at a dedicated locker. Skip the line and get on your way!
