Roaming vs an eSIM for Tokyo

Getting around Tokyo with data

Tokyo's rail and subway network is extensive, and apps like Google Maps and Japan Transit Planner make navigating it far easier with a live connection. From ordering at ramen shops with translation apps to booking a table in Shibuya or Shinjuku, having data from the moment you land at Narita or Haneda helps from the very first step outside arrivals.

How much data does a Tokyo trip need?

• Maps, transit apps and messaging: about 300-500MB per day
• Social media and photos: add 500MB to 1GB per day
• Video calls or streaming: 1-2GB per hour

A short 4-7 day trip with normal use fits comfortably on a fixed-data or Unlimited Essential plan; choose Unlimited Plus if you expect to hotspot a laptop or stream often.

Pro tips for Tokyo travelers
