Why Driftvoy for Japan

Built for Japan travel.

Full-speed throughout your trip

Most "unlimited" Japan plans throttle to 1 Mbps after 3 GB per day. Our plans give you the full carrier speed until your data is exhausted. Maps load. Streaming works. Hotspot stays usable.

Same eSIM, every top-up

When you run low, top up from your account — no reinstall, no new QR code, no waiting. Add data and validity to your existing eSIM up to 10 times per ICCID.

Money-back guarantee

If your eSIM isn't delivered or fails to activate, you get a full refund.

Network coverage

Coverage you can count on.

Driftvoy's Japan plans connect to KDDI au and Softbank— two of Japan's three major carriers, covering the entire country. Strong 4G/5G coverage in Tokyo, Osaka, Kyoto, Nagoya, Sapporo, Fukuoka, and across the Shinkansen lines. Reliable on smaller cities and rural areas where supported by carrier infrastructure.

Not currently using NTT Docomo. If you're traveling primarily to remote mountain regions or very small islands where Docomo's coverage is uniquely strong, check our How We Compare page for alternative providers.
