What is the internet coverage like with EastESIM at Mount Fuji in Japan?

When visiting the iconic Mount Fuji region in Japan, EastESIM provides excellent internet coverage around the popular Five Lakes area (like Lake Kawaguchiko) and in nearby towns such as Fujikawaguchiko. You'll have strong 4G/5G signal to share breathtaking photos of Fuji-san, check bus schedules, or navigate to scenic viewpoints. If you're hiking during climbing season, signal will be available at the lower stations and huts. However, as you ascend towards the summit, especially in more remote sections, connectivity may become intermittent due to the altitude and terrain.
