From checking train connections in Tokyo to sharing photos from Kyoto, Japan eSIM NTT Docomo keeps you connected on Docomo's native 4G/5G network as you plan your next stop. Our testing showed strong performance during peak hours, making it a practical choice for travelers who value speed and connection stability in Japan.
Choose a total-data or daily plan to suit your trip, with daily options offering 5GB, 30GB or 100GB of high-speed data. If you regularly watch videos, upload travel memories or use large amounts of data, the 100GB-per-day option gives you a generous, clearly defined high-speed allowance, making your daily usage easier to manage.
On daily plans, you can continue browsing at 200kbps after using up your daily high-speed allowance. Your high-speed data allowance resets every day at 00:00 Japan time (UTC+9). iOS devices configure the APN automatically; Android devices require manual APN setup using a.apn02.net.
