FAQ
For Tokyo, Osaka, Kyoto, maps, translation, messaging, and light social use, many tourists fit 5-8 GB per week. Add more for video, hotspot, heavy photo uploads, or rail-heavy itineraries.
Moderate users often fit 8-12 GB for two weeks. Heavy users, hotspot sharing, or travelers using navigation and translation all day may prefer 15 GB+ or an unlimited-style plan with clear fair-use terms.
For most short tourist trips, a prepaid Japan travel eSIM is the cheapest practical option because you pay upfront for the data and days you need. Pocket Wi-Fi can be useful for groups but adds rental logistics.
Hotel and station Wi-Fi can help, but relying only on public Wi-Fi is inconvenient for maps, train changes, translation, and rides. Mobile data is worth having when you are outside or moving between cities.
