Japan eSIMs with Phone Number, Calls, & Texts

Getting a Japanese mobile number (with country code +81) typically requires undergoing the KYC process. This means you will need to visit a local telco or carrier shop and present your passport for registration. This is why there are not a lot of eSIMs with a Japanese phone number that are readily bookable online.

However, there are still a few options that you can consider. The first one would be Airhub. Their data and voice plan for Japan comes with a free international phone number and 15 minutes of domestic calls in Japan. The second one would be aloSIM, which offers eSIMs with SMS, voice, and a free international phone number. This is ideal if you want to make both domestic and overseas calls while traveling.

For Klook Users

If you usually book your trip on Klook, Asia’s beloved travel activity booking platform, here are the links to their top-selling Japan eSIMs:

• 4G/5G Japan eSIM by Klook (Purchased over 700k times)
• 4G/5G Japan eSIM by SoftBank (Booked more than 100k times)
• 4G Japan eSIM by Sakura Mobile (Bought more than 20,000 times)

The first option, SoftBank, is the official prepaid eSIM of the carrier, while the third option also comes from a reputable Japanese travel internet company. The second option is Klook’s branded Japan eSIM, which comes with unlimited data, a very simple in-app installation, and up to 5G internet speeds from NTT Docomo.

Regional eSIM for Japan, Korea, & China

If you are traveling to East Asia, including Japan, China, and South Korea, you will be better off purchasing 1 eSIM data plan instead of multiple. As of writing, only Nomad eSIM has this three-country plan, which starts at only $4.

Top Japan eSIM Providers with Reviews

In recent years, tourists bound for Japan either use a physical SIM card or rent a pocket WiFi from Ninja WiFi. However, many travelers have switched to using an eSIM (short for embedded SIM) for convenience and cheaper pricing. Personally, I have used several eSIMs in Japan, and they all worked just like my go-to SIM cards, except that I did not have to pick them up at the airport and install them on my phone. All I had to do was buy an eSIM online, install it, and activate the eSIM to start browsing.

Nowadays, there are so many Japan travel eSIMs to choose from, and I guess you can say that this is the only problem about purchasing one. There’s too many! To help you, our team wrote this shortlist of various providers that highlight their best features, reviews, and coupon code. We hope this guide helps with your planning.

Ah, Ubigi. The most popular eSIM for Japan. Millions of tourists choose this provider, which is a subsidiary of the local Japanese network NTT Docomo.

But Ubigi offers more than 5G speeds; our team also recommends them for their offline top and reusable eSIM functions. In case you run out of data, you can easily purchase another data pack even without WiFi. Plus, after installing Ubigi’s eSIM once, you won’t have to do so ever again on your future adventures. Simply purchase a data plan for Japan or any of the 200+ destinations that they service, and you’ll be connected online with no hassle
