How much mobile data is required for a week-long Tokyo mission?

For a typical 7-day mission exploring Tokyo's diverse districts like Shinjuku, Shibuya, and Ginza, a data allocation of 5-10 GB is generally sufficient. This covers critical navigation, social media updates, secure messaging, and light streaming. If your operational tempo includes extensive video conferencing, large data transfers, or tethering multiple devices, consider a 15-20 GB plan to ensure uninterrupted connectivity and prevent unexpected data shortfalls. eSIM Scout provides flexible options to match your specific needs.
