Quick verdict
NINJA WiFi is worth considering for families, groups, and travelers who want to connect several devices in Japan using a rental Pocket Wi-Fi router, or who prefer a physical SIM or eSIM as separate product options. Each product has its own setup, compatibility, and logistics, so the right choice depends on the exact product selected. It may be less suitable for solo travelers who prefer not to carry, charge, or return a device — always confirm current pickup, return, and plan details on the official website before booking.
