Saily’s Japan eSIM covers Tokyo and the rest of Japan: $3.99 for 1 GB, $10.99 for 5 GB, and unlimited plans if you stream or work on the go.
The catch: plans are data only, so you get no local phone number for calls or texts.
Tokyo’s train network is easy with live maps, and you’ll use data for translation, restaurant bookings and finding your way out of huge stations. A Japan eSIM is ready when you land at Narita or Haneda.
