From the arrivals hall to the right station exit

Your phone can help with station exits, connections and showing your accommodation address in Japanese. Save the hotel name, booking and first journey offline so they are ready while you sort out luggage and connectivity.

Can I rely on city Wi-Fi?

Tokyo and Kyoto offer public Wi-Fi hotspots, but these are individual locations rather than a continuous connection along your route. Download maps before exploring and choose mobile data for your navigation, messages and usual usage.

What should I prepare for the first transfer?

JNTO describes rail, bus and other airport transport options. Before departure, check the route from your actual arrival airport, save your address in Japanese and review the timetable for your arrival time.

Before your Japan trip

Which networks are available with a Japan eSIM?

The current catalogue lists KDDI/au (5G), NTT docomo (5G), Rakuten Mobile (5G), and SoftBank (5G). Check your selected package before purchase: the combined country list does not mean that every tariff accesses every operator.

Are NRT and HND terminals at the same airport?

No. Narita and Haneda are separate airports. If the codes differ on your tickets, check ground transport and your airline's connection requirements before booking connecting flights.

Is free Wi-Fi available in Kyoto?

Kyoto's official tourism website lists public hotspots. Do not treat them as a connection at every point on a walk: save addresses and directions and arrange mobile data for access away from hotspots.

When should I install my eSIM for Japan?

Check the selected tariff’s activation trigger, as rules can differ. If validity starts on installation, installing early uses part of that period; if it starts on first connection to a supported destination network, you can prepare the profile beforehand.

Does the plan cover my next country in Asia?

Only if every country on your itinerary is explicitly included in the selected plan. Review the available regional alternatives and check each stop in the product’s coverage list before buying. A region name alone does not confirm coverage in a particular country.
