Tokyo, Kyoto, Osaka — one eSIM for the golden route?

Yes — one Japan eSIM covers the whole country, so the classic Tokyo–Kyoto–Osaka route needs nothing extra.

Does one eSIM cover several Asian countries?

A Japan eSIM covers Japan only. For multi-stop Asian itineraries, the Asia regional eSIM covers 32 countries on a single plan and hops networks automatically as you travel.

Will my eSIM work as soon as I land in Japan?

Yes — install it at home on Wi-Fi before you fly, then switch the line on when you land. It joins a partner network in Japan automatically, usually before you reach baggage claim. Your days only start counting at that first connection.

Do I keep my own number and WhatsApp in Japan?

Yes. This is a data-only eSIM that runs alongside your home SIM. Your number stays active for calls and texts, and WhatsApp keeps working on your usual number the whole trip.

When do my days start counting?

Only when the eSIM first connects to a network in Japan — not when you buy or install it. Buying ahead of your trip is completely safe.

Which phones work with a Japan eSIM?

Most phones from 2018 onward: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus many recent Xiaomi, Oppo and Motorola models. Your phone must also be carrier-unlocked — check yours in 30 seconds on our compatibility page.

Good to know

Japan runs on QR codes and maps — from ramen-shop queues to Shinkansen seats. Unlimited data is the right call here.

The Japan eSIM guide.

No destination rewards good data like Japan: navigation through Tokyo's stations, translation everywhere, restaurant queues managed by app, and the Shinkansen timed to the minute. Japanese networks are superb — your eSIM rides them the whole trip.

How it works on the day

Install at home, switch on at Haneda, Narita or KIX. Coverage holds along rail corridors and underground in the metro, so the golden route just works.

Choosing your days

The classic 10–14 day Tokyo–Kyoto–Osaka route lands in the discounted day-rate band.

Japan eSIM questions, answered.
