Yes, Genki Mobile’s pocket Wi-Fi provides internet access across most of Japan, including major cities and many rural areas. Genki Mobile’s 1GB per day Pocket Wi-Fi plan uses NTT Docomo’s network, which offers the widest coverage in Japan and is well suited for travelers visiting both urban and countryside areas.
The 7GB per day plan uses cloud SIM technology on SoftBank and KDDI networks. While coverage in very remote locations such as mountains or forests may be slightly weaker compared to NTT Docomo, it still delivers strong and reliable internet access throughout most of Japan. Travelers can begin using Pocket Wi-Fi immediately after landing at airports such as Haneda or Narita.
