Yes, having reliable data from EastESIM is highly recommended for seamless navigation across Japan. While public transport is excellent, real-time updates on train delays, bus routes, or even finding the best ramen shop in a bustling district like Shibuya or Dotonbori often rely on apps like Google Maps or Japan Transit Planner. Even in charming rural areas like Hokkaido or Kyushu, a stable connection helps locate hidden shrines or scenic viewpoints, ensuring you make the most of your journey without getting lost.
