Overview

The 365チャージWiFi is a prepaid mobile WiFi router that requires no contract and no monthly fees. You purchase the device once, and it comes with 100GB of data pre-loaded, valid for one full year. It uses a cloud SIM that supports Japan's three major carriers—docomo, au, and Softbank—so there's no need to insert a physical SIM card. The accompanying app lets you top up data anytime, making it an excellent choice for short-term trips, business travel, or as a backup connection.
This product stands out for its buy-it-outright model. There's no rental fee or cancellation charge; you simply own the device and use the included data until it runs out. Bear in mind that it's limited to 4G LTE (no 5G), so it's not meant for ultra-high-speed tasks, but it handles everyday browsing, video streaming, and video calls without issue. The compact pocket-sized form factor is ideal for carrying around or keeping in a car.

Connectivity & Compatibility

  • Network Support: 4G LTE on docomo, au, and Softbank via cloud SIM. No physical SIM required. The device can also be used overseas if you top up an international data plan separately.
  • Wireless Standard: Wi-Fi 6 (802.11ax) with dual-band 2.4GHz and 5GHz. The maximum number of simultaneous connections isn't officially stated, but based on similar cloud SIM routers, it's likely around 10 devices.
  • Compatible Devices: Any device with Wi-Fi, including smartphones, tablets, laptops, game consoles, and security cameras. 5G-only devices will not benefit from this router.
  • Setup: Turn on the power and the cloud SIM activates automatically. The Wi-Fi network appears with a password printed on the device. No complex configuration needed.

Product Info

  • Release: Appeared on online retailers around 2024.
  • Pricing: Device + 100GB data bundle is approximately ¥24,200 (tax included). Additional data packs: 1GB ¥980, 10GB ¥1,480, 20GB ¥2,880, 30GB ¥3,280, 60GB ¥4,980, 100GB ¥6,480.
  • Warranty: Manufacturer warranty not clearly stated; standard online retailers return policy likely applies.
  • Accessories: Unit, USB charging cable, manual. AC adapter may need to be purchased separately.
  • Market Position: Entry to mid-range. It combines Wi-Fi 6 and cloud SIM convenience at a prepaid price point. The lack of 5G and the limited initial data cap make it best for light users or as a secondary connection.

Best Use Cases

  • Short-term travelers or business people: No contract means you can use it for a few weeks and then put it away. Great for trips where you don't want to hunt for local SIMs.
  • Patients in hospital or temporary residents: If you need internet for a month or two without a long-term commitment, this prepaid router is ideal. 100GB is enough for streaming and social media.
  • In-car WiFi: Small enough to keep in the glovebox. Power it via a USB car charger. However, 5G is absent, so don't expect super-fast speeds for large downloads.
  • Not for: Heavy data users exceeding 100GB per month, anyone requiring 5G speeds, or those needing guaranteed stable high-speed connectivity. Performance varies by location and network congestion.
