Will my eSIMFlyer internet signal reach the summit of Mount Fuji?

Updated April 22, 2026

Remarkably, yes! During the official climbing season, typically from July to September, major network carriers provide robust 4G coverage along the hiking trails and even right at the summit. With eSIMFlyer, you can live-stream the iconic sunrise, known as Goraiko, directly from the peak, ensuring your global connections remain active even at high altitudes.
