Japan's Advanced Mobile Infrastructure

Japan operates one of the world's most sophisticated mobile networks. Tokyo, Osaka, and Kyoto offer extensive 5G coverage, while the shinkansen (bullet train) routes maintain consistent connectivity at 300+ km/h speeds. This advanced infrastructure makes eSIM technology not just convenient, but essential for modern travelers.
