Staying connected in Tokyo is straightforward, with several good options depending on how long you’re staying.
eSIM (Best for Short Stays)
Providers like Ubigi, Airalo, and Sakura Mobile offer Japan-specific eSIM plans that can be activated before you land — genuinely the easiest option if your phone supports eSIM (most phones from the last several years do). Plans typically run $15–30 for 5–20GB over 1–4 weeks.
Physical SIM
For longer stays, a physical SIM from Mobal or Sakura Mobile can be ordered online before arrival or picked up at the airport, and importantly, these providers don’t require a Japanese address or bank account — a common blocker with mainstream carriers for newcomers.
Pocket Wifi
A popular alternative, especially for groups or those traveling with multiple devices — rent a pocket wifi router at the airport (or have it delivered to your hotel) that provides wifi to several devices at once, often at a better data-per-dollar rate than a phone-only SIM.
Where to Buy
- Airport kiosks at Narita and Haneda are the most convenient but can be pricier — pre-ordering online usually saves money.
- Bic Camera and Yodobashi Camera (electronics chains) sell tourist SIMs in-store across the city.
- 7-Eleven and some convenience stores stock prepaid data SIMs as well, though selection varies by location.
The Bottom Line
For most visitors, an eSIM ordered before the trip is the simplest option — no airport queue, no extra device to carry, and immediate connectivity on landing.
Frequently Asked Questions
Can I get a Japanese phone number without a Residence Card?
Generally no for mainstream carriers, but data-only tourist SIMs and eSIMs don’t require one — a full Japanese number typically requires residency status.
