Overview

The 365チャージWiFi is a prepaid mobile WiFi router that requires no contract and no monthly fees. You simply purchase the device, and it comes with 100GB of data valid for 365 days. It features a built-in cloud SIM that automatically connects to Japan's major carriers (docomo, au, Softbank), so there's no complicated setup—just turn it on and connect.
This product stands out because it eliminates the long-term commitments typical of traditional pocket WiFi services. There are no cancellation fees or minimum usage periods. The battery is advertised as long-lasting, making it suitable for travel and outdoor use. It supports Wi-Fi 6 (802.11ax) and can connect up to 10 devices simultaneously.

Connectivity & Compatibility

The 365チャージWiFi uses a cloud SIM that selects the best available 4G LTE network among docomo, au, and Softbank. It does not support 5G, but 4G LTE coverage is extensive across Japan. Any Wi-Fi-enabled device—smartphones, tablets, laptops, game consoles, smart TVs—can connect. Up to 10 devices can be connected at once, making it suitable for sharing with family or colleagues.
Wireless standards include 802.11ax (Wi-Fi 6), 802.11b/g/n, and dual-band operation (2.4GHz and 5GHz). This ensures stable connections even in crowded environments.

Product Info

The 365チャージWiFi launched around 2024 and is positioned as an entry-level to mid-range mobile router. Its prepaid model is ideal for short-term use, backup connectivity, or travel. The 100GB bundle is priced around ¥24,200 on Japanese online retailers. After the initial data is used, you can top up with additional data packs (1GB for ¥980 up to 100GB for ¥6,480). A dedicated app (iOS/Android) lets you check remaining data and purchase top-ups in real time.
Warranty details are provided by the manufacturer; accessories include a USB charging cable and manual.

Best Use Cases

  • Travelers and business trips: Avoid relying on hotel or airport Wi-Fi. 100GB is enough for streaming and remote work. No contract means you can keep the device for future trips without ongoing costs.
  • Temporary residents or moving: Use as a bridge until your home internet is installed. No cancellation hassle when you no longer need it.
  • Car use and outdoor activities: The long battery makes it practical for camping, road trips, or in-vehicle use. However, it lacks 5G, so heavy data users may find speeds limiting.
  • Backup internet: Keep as a spare for emergencies or share data with family. Note the 10-device limit; heavy simultaneous usage may affect performance.
