Not a restaurant review. A packet-network question for a week in Tokyo.

Restaurant and hotel Wi-Fi are not a plan. Maps, translate-camera, and IC top-up from the app still want data after you walk outside.

Copied checkout 2026-08-29 (re-check): Airalo Japan 7d 5GB $10 / 10GB $17; unlimited 7d $27 is FUP 3GB/24h then ~1 Mbps. Holafly 7d $27.50, hotspot 1GB/day. Ubigi 10GB/7d $14 on Docomo.

eSIM is not Suica. Welcome Suica Mobile is JR East, 180 days, no refund (March 2026). Most US/EU Android cannot tap. Plastic IC for gates.
