🇯🇵 Japan
Tokyo eSIM
Land in Tokyo, scan a QR, and you're online on a local network in seconds. No daily roaming fee, no surprise bill. $1.60 per GB.
Data in Tokyo
In Tokyo the eSIM rides NTT Docomo and SoftBank with 4G / 5G typically available - the same towers local subscribers use, selected automatically by signal strength. City centers, transit, and airports are the strongest coverage any network offers, so this is the easy case. Excellent nationwide, including Shinkansen lines and subway tunnels. Remote mountain onsen towns may drop to 4G.
Pricing is Japan's flat rate of $1.60/GB, metered per MB from a prepaid USD balance. A city break runs light: maps, ride-hailing, translation, and messaging together use well under 500 MB a day for most travelers, so $10 (≈ 6.3 GB) commonly outlasts the trip - and whatever's left keeps working in the next city, or next year.
Arrival checklist
- 1. Install the eSIM on Wi-Fi before you fly (QR or one-tap iPhone install).
- 2. Turn Data Roaming ON for the Anon eSIM line; leave it off on your home SIM.
- 3. Set Anon eSIM as the mobile data line; keep calls/SMS on your primary.
- 4. Land in Tokyo, drop airplane mode, and you're connected within a minute.
No ID, no account, no email - $5 minimum plus a one-time $5 setup fee for a new eSIM. Top-ups later are fee-free.
On the ground in Tokyo
Haneda and Narita both cover 5G on Docomo and SoftBank at every gate; the eSIM attaches during taxi. Central Tokyo runs dense mid-band 5G with 300-800 Mbps typical - among the fastest large-city speeds anywhere. All JR and metro lines have continuous underground coverage, including the deepest sections of the Ōedo line. Shinkansen routes stay on 5G in stations and switch to LTE at 300 km/h between them, without dropping. Coverage stays complete across Yokohama, Kamakura, and out to Nikko.
