Your free eSIM connects automatically to these mobile carriers — the same networks locals use, no SIM swap required.
Walk off the jet bridge with maps, ride-hailing and messaging already working at these arrival points.
Strong 4G/5G across the cities and neighbourhoods most travellers actually visit.
Shinjuku and Shibuya for the neon and the crowds, Asakusa for Sensō-ji and the old low city, Ginza for the department stores — and a rail map that makes all of it 20 minutes apart.
The temple city: teahouses and lantern-lit lanes in Gion, the bamboo grove and river at Arashiyama, and the torii tunnels climbing the hill behind Fushimi Inari.
Japan’s kitchen — the canal-side signs and street food of Dōtonbori, the towers and stations of Umeda, and the deliberately retro alleys of Shinsekai under Tsūtenkaku.
Hokkaidō’s capital: the bars and ramen alley of Susukino, the park spine of Ōdori that hosts the February snow festival, and the canal warehouses of Otaru half an hour up the coast.
Kyūshū’s gateway and the closest big Japanese city to Korea: Hakata’s tonkotsu ramen and its shinkansen terminus, the shopping of Tenjin, and the riverside yatai food stalls of Nakasu.
The eSIM gets you online — these are the local apps it unlocks the moment you arrive.
Japan has no Uber for ordinary taxis — GO is the app that hails the real ones. It matters most late at night in Kyoto and outside the big stations, where flagging one down on the street can take a while.
Puts the IC card in your phone, so you tap through gates and pay at convenience stores without hunting for a ticket machine. Adding it to Apple Wallet works with a foreign card; the Android app is more particular, so set it up before you fly.
Routes that name the actual platform and carriage, and filter by whether a Japan Rail Pass covers the train — the distinction that decides whether your next leg is free or ¥14,000.
The domestic restaurant reference, and its scoring is famously harsh — anything above 3.5 is genuinely very good. Worth learning, because the ratings are not comparable to what you are used to elsewhere.
What you’d pay at the airport SIM kiosk — and what you save by activating the eSIM before you fly.
Honestly: ¥3,000–5,000 buys eight days of effectively unlimited data at a Haneda or Narita counter, which is far more than 1 GB. This is for landing already online — no counter, no vending machine, no queue after a long-haul — and you can top up if a week of maps and translation eats through it.
Try our cutting-edge eSIM technology for free across all 33 European destinations.
Enough for maps, messages, ride-hailing and light browsing when you arrive — works from France and Germany to Iceland and Greece.
Add more data or extend your validity whenever you need it — top-ups stack onto the same eSIM, no reinstall, no SIM swap.
Connects to top local carriers — the same fast, reliable networks our paid plans use.
