Suitable for: 1. Short-haul travelers: The card has a fixed 5-day validity period. Suitable for travelers on short trips of 5 days/4 nights or 4 days/3 nights in Japan (such as weekend getaways or mini-holiday trips). 2. Heavy internet users and business travelers: Features unlimited data and ultra-high-speed 4.5G/5G networks. Suitable for heavy users who need to watch HD videos, stream live, and play online mobile games anytime, anywhere. Also suitable for business travelers who need to work remotely, frequently conduct video conferences, and upload large work documents while traveling. 3. Travelers on full-day in-depth tours or those traveling between multiple locations: The product explicitly supports multiple locations throughout Japan, including Tokyo, Osaka, Kagoshima, Hokkaido, Nagoya, and Fukuoka. Suitable for travelers crossing the Kanto and Kansai regions by Shinkansen, or traveling to more remote areas such as Hokkaido and Kyushu. Docomo, as Japan's largest mobile network operator, boasts the widest base station coverage, with signal stability far exceeding that of other secondary networks in suburban, mountainous, and rural areas. 4. Perfectly matched for pure network users (no need for calls within Japan): This product is positioned as a data card/internet card/SIM card, without a traditional Japanese phone number. Suitable for travelers who only make voice/video calls via apps like WeChat, WhatsApp, LINE, and FaceTime, and do not need to make physical calls to Japanese numbers (e.g., to make restaurant reservations or contact guesthouse owners). 5. Perfectly matched for traditional mobile phone users who prefer plug-and-play functionality: This is a physical SIM card. Suitable for users whose phones do not support eSIM functionality, or who prefer to connect to the network in Japan by "removing and replacing their SIM card," and who value simple operation and plug-and-play functionality.
