While Tokyo offers some public Wi-Fi in major train stations, cafes, and tourist spots, it can be unreliable, slow, or require complex registration. For consistent, secure, and high-speed internet access for navigation, translations, and ride-sharing apps across the city, an eSIM is far more dependable than public Wi-Fi, especially when exploring areas like Akihabara or Asakusa.
