Japan eSIM.
Tokyo neon to Kyoto's temple lanes — data that keeps up on the golden route.
Every plan: QR by email in minutes · data-only, keep your number · days start on first connection · top up anytime · the total shown is the whole bill. What's included →
Unlimited plans run at full speed up to a daily fair-use allowance, then at reduced speed until the allowance resets the next day — you're never cut off. Every plan is prepaid: the checkout total is the whole bill, and we never add overage charges.
Hotspot support varies by plan and destination — where it's available for your plan in Japan, it's shown in the plan details before you pay.
The Japan eSIM guide.
Nowhere pays you back for good data quite like Japan. You navigate Tokyo's stations by phone because the signage defeats everyone, you translate constantly, you put your name down for a restaurant on an app and get a text when the table's ready, and the Shinkansen leaves to the second, with or without you aboard. The networks here are among the world's best, and your eSIM rides them start to finish.
How it works on the day
Getting online is the easy part: install at home, switch on as you land at Haneda, Narita or Kansai, and you're connected before you've found the right train into town. Coverage holds along the rail corridors and even underground in the metro, so the Tokyo–Kyoto–Osaka run never leaves you guessing.
Choosing your days
That golden-route trip — Tokyo, Kyoto, Osaka, maybe Hiroshima on the end — is usually a 10-to-14-day affair, and that's precisely the length that slides into the cheaper day rate.
Before you land in Japan.
Narita, Haneda and Kansai all sell tourist SIMs, but counters keep opening hours and queues follow long-haul landings — an eSIM installed at home is already working on the train into town.
Suica and PASMO travel cards now sit in Apple Wallet and Google Wallet, and topping up on the go needs a connection — one more reason to land online.
The classic rental puck is a second device to collect, charge and return; your own phone's hotspot on an eSIM does the same sharing job without the return-desk deadline.
Many small restaurants, shrines and ticket machines still prefer cash; convenience-store ATMs take foreign cards, and finding the nearest one is a maps-and-data job.
Signal along the Shinkansen corridors and underground in the metro is generally excellent; remote mountain valleys and small islands can still drop coverage, as on any network.
Discover Japan.
The short version.
A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Japan, and it finds a partner network on its own.
