Unlimited Data in Japan: Fair Use Realities
Many providers advertise “unlimited data,” but most enforce fair-use caps—often between 1–3 GB per day, after which speeds are throttled significantly. This applies to Japan as well; unlimited plans work well for general browsing but may choke on heavy video streaming.
Japan’s networks—NTT Docomo, KDDI, and SoftBank—offer excellent 4G and expanding 5G availability, especially in cities. Most eSIM providers, RORO included, lease access through these carriers. So even if RORO doesn’t highlight the exact partner, performance is typically trustworthy in popular urban areas. Rural coverage, while still strong, may vary—so check beforehand if your itinerary ventures off the beaten.
