Why use an eSIM in Tokyo?
From high-tech vending machines to ancient shrines tucked between skyscrapers, Tokyo is full of surprises. But not being connected shouldn’t be one of them. Whether you're booking a Shinkansen, translating menus, or hotspotting for a Zoom call, data is essential.
eSIMs give you:
✅ Instant access without visiting a store
✅ No physical SIM card swaps
✅ Coverage in metro areas, suburbs, and even the train tunnels
✅ Easy plan switching if needed
What is an eSIM?
An eSIM (embedded SIM) is a digital version of a traditional SIM card. You install a virtual profile from your provider, no plastic, no shipping, no waiting. If your phone supports it, all you need is a QR code or app.
