Get Japan eSIM: data plans for a Japan trip, from $12

Shopping at Get Japan eSIM? See all current Get Japan eSIM promo codes and deals, checked regularly.

Get Japan eSIM does one thing: data-only eSIMs for visitors to Japan. It's run by COCODAKE Co., Ltd., a company based in Chuo-ku, Tokyo, and you buy on its website without needing an app. Pay through Stripe (cards, Apple Pay or Google Pay), and the QR code arrives by email within minutes. Scan it in your phone's settings and the eSIM sits alongside your normal SIM, so your US number and WhatsApp keep working while the eSIM handles data.

It suits US travelers heading to Japan who'd rather have a short, clear choice of plans than scroll through dozens. All six plans run on 4G LTE, include hotspot tethering, and only start counting days when the eSIM first connects to a network in Japan, so you can install it at home before you fly. The site says coverage reaches all 47 prefectures, from Sapporo to Okinawa.

What's worth a look

There are three Japan plans and three multi-country plans, priced per trip in US dollars.

For a typical week or so in Tokyo, Kyoto and Osaka, the 10GB for 10 days plan at $15.00 is the one the site marks as most popular, and 10GB is plenty for maps, train times and messaging. Staying longer, or a heavy user of video calls? The Unlimited for 30 days plan at $36.00 takes the guesswork out. If your trip takes in South Korea or China too, the multi-country plans cost a little more than the Japan-only ones but save buying a second eSIM.

Before you buy, check your phone supports eSIM (the site lists iPhone XS and later, Google Pixel 3 and later, and Samsung Galaxy S20 and later) and that it's carrier-unlocked. Its terms say refunds aren't given once the QR code has been issued, except for a technical fault on its side reported within 7 days.

How to save more

• Match the plan to your trip length rather than going straight for Unlimited. The 3GB plan at $12.00 covers a short city break if you mostly use hotel Wi-Fi.
• Only buy a multi-country plan if you're actually crossing borders. For Japan alone, each Japan plan is cheaper than its multi-country version.
• Install over Wi-Fi at home and leave the eSIM line switched off until you land, so none of your days are used up in transit.
