Overview

The HUNDRED Wi-Fi Charge Type is a prepaid mobile router that bundles the AIR-1 device with 100GB of domestic data valid for one year. With no monthly fees, no contract, and no binding period, it's a buy-and-use solution ideal for users who want a straightforward internet connection without the hassle of carrier paperwork. The router measures roughly 126 x 68 x 12.1 mm and weighs only about 130g, making it very portable.
It supports Japan's four major carriers (docomo, au, SoftBank, Rakuten Mobile) and automatically selects the best available LTE network. Maximum theoretical speeds are 150 Mbps down and 50 Mbps up, which is sufficient for streaming video, web browsing, and social media. The device also works in over 135 countries and regions, provided you purchase additional overseas data packs.

Connectivity & Compatibility

  • The router operates only on 4G LTE networks (no 5G support). For most everyday tasks and moderate data usage, LTE coverage in Japan is adequate. However, in congested areas or for heavy downloads, you may experience slower speeds compared to 5G or wired connections.
  • It functions as a Wi-Fi access point using 802.11b/g/n on the 2.4 GHz band, supporting up to 10 simultaneous connected devices. There is no 5 GHz Wi-Fi band, so interference from other household devices can occasionally reduce performance.
  • When traveling abroad, the device automatically connects to a local carrier. You must pre-purchase an overseas data pack through the HUNDRED Wi-Fi Buy official store to use data internationally.

Product Info

The HUNDRED Wi-Fi Charge Type was released around 2024 and is available on Japanese online retailers for approximately ¥21,800. This price covers both the AIR-1 router hardware and the 100GB data allowance that expires 365 days after first activation. Accessories include a USB cable and quick-start guide; a power adapter is not included and must be supplied separately. Warranty details are available from the manufacturer.
Positioned as an entry-to-mid-tier prepaid mobile router, it competes with contract-based SIM plans and portable Wi-Fi devices. Its key advantage is the no-contract, upfront payment model. If you use less than about 8-9 GB per month on average, the total yearly cost can be lower than typical prepaid SIMs with similar data allowances. However, once the 100GB is consumed, you need to purchase a recharge pack (domestic 100GB costs ¥6,980 in the official store).

Best Use Cases

  • Short-term or temporary internet needs: For example, after moving into a new apartment before your home internet is installed, or as a backup connection during business trips. The router arrives ready to use, no activation process needed.
  • Budget-conscious light users: If your monthly data consumption typically stays under 9GB, the one-time fee of ¥21,800 works out to roughly ¥1,816 per month over a year. This can be cheaper than most prepaid SIM plans. Keep in mind that once you run out, recharging is relatively expensive (¥6,980 for another 100GB).
  • Car or outdoor use: The compact size with a USB power input makes it easy to use in a vehicle with a cigarette lighter adapter. Note that the router does not have a built-in battery; it requires continuous USB power to operate. If you need true portability without external power, this product is not suitable.
