Overview

The 365ChargeWiFi is a prepaid mobile WiFi router that requires no contract and no monthly fees. You purchase the device outright, and it comes with 100GB of data pre-loaded, valid for 365 days. It uses a built-in cloud SIM that connects to Japan's major carriers—docomo, au, and Softbank—over 4G LTE. No physical SIM card insertion is needed; just power on and connect. Up to 10 devices can be connected simultaneously, making it ideal for smartphones, tablets, laptops, and gaming consoles. The dedicated "365ChargeWiFi" app lets you check remaining data and purchase additional gigabytes in real time, 24/7. This is a true pay-as-you-go solution with no hidden costs.

Connectivity & Compatibility

This router supports 4G LTE networks from docomo, au, and Softbank (5G not supported). It features Wi-Fi 6 (802.11ax) with dual-band (2.4GHz/5GHz) for stable connections. Up to 10 devices can connect at once, perfect for sharing with family or friends. Compatible devices include any Wi-Fi-enabled device: smartphones, tablets, PCs, gaming consoles, and even security cameras. It can also be used overseas with additional data purchase (separate gigacharge required), making it a flexible travel companion. However, check supported countries before traveling.

Product Info

Released in late 2024, the 365ChargeWiFi is available on Japanese online retailers for ¥24,200 (tax included), which covers the device and the initial 100GB data. Warranty is provided by the manufacturer (details on the product page). Accessories include the router, USB charging cable, and manual. Market positioning is entry to mid-range: it's a no-commitment solution for users who need temporary or low-maintenance internet access. Additional data can be purchased via the dedicated app, with prices ranging from ¥980 for 1GB to ¥6,480 for 100GB. The device is compact and portable, making it popular for car use.

Best Use Cases

  • Temporary residents or travelers: Perfect for short-term stays in Japan—no contract, no setup fee, and the data lasts a full year. No cancellation procedures needed; just stop using it when done.
  • In-car WiFi: Keep it in your car for on-the-go connectivity. Since there's no monthly fee, it's cost-effective for occasional use during road trips or camping.
  • Users avoiding long-term contracts: If you dislike monthly commitments and want a pay-once solution, this router is ideal. You only pay for additional data when you need it. Great for students or those on temporary assignment.
  • Backup connection: Use it as a fallback when your main fiber line goes down. No monthly cost means it's a cheap insurance policy.
  • Not recommended for: Heavy data users who consume over 100GB per month, or those requiring 5G speeds. The add-on data is relatively expensive, so a regular SIM plan may be more economical. Also, mobile network speed can vary, so it may not suit users needing ultra-stable connections like fixed-line broadband.
