What is eSIM?

7 Best Tourist eSIMs in Japan

Before diving into the list of the best eSIM services, it’s important to understand what eSIM is. This relatively new technology has gained attention in recent years.

The term “eSIM” refers to “Embedded SIM.” Introduced in 2016, most modern mobile phones now support this feature. The eSIM eliminates the need for a physical SIM card, making it cheaper and easier to install. Users only need to scan a QR code or install an app on their mobile phone.

While eSIM technology has been available for some time, it gained significant attention when Apple announced that the iPhone 14 would solely utilize eSIM. Consequently, companies that haven’t supported eSIM will now start embracing it as the standard, gradually replacing physical SIM cards.

Now that we are familiar with eSIM, let’s explore five of the best eSIM services in Japan. Please note that while most mobile phones are compatible with eSIM, it’s advisable to check compatibility before making any purchases.

1. eSim Japan

eSIMJapan offers cost-effective data-only plans for tourists visiting Japan. They have two types of plans: a general Japan plan, and city-specific plans for Tokyo, Osaka, Kyoto, and other cities.

Ordering an eSIM is convenient as you receive a QR code within 2 minutes via email, allowing you to pick it up while waiting for your luggage at the airport. The plan starts immediately after scanning the code and installing the eSIM. Plans have different durations (3, 5, 7, 12, 15, or 20 days) and data limits (3GB, 5GB, 10GB, or unlimited), so you can choose one that suits your trip length. Prices range from ¥569 for a basic 3-day plan to ¥3,279 for an unlimited 12-day plan. While eSIM Japan is provided by China Mobile Hong Kong, it roams on Japan’s SoftBank network.
