However, if you only need an international phone number (not necessarily issued in Japan), you can also consider getting this eSIM from aloSIM. They offer free credits for calls and texts and a 15% discount with our promo code TRAVLISTS.
• Airalo vs. Ubigi. Our team at Travlists has tested both eSIMs in Japan, and both of these providers offered top-notch internet connections. However, Ubigi’s data plans are slightly cheaper than Airalo’s, making it more popular among our readers. Whether you choose Ubigi or Airalo for your Japan eSIM, you can use our promo code TRAVLISTS on Ubigi here to get 10% off or promo code TRAVLISTS15 on Airalo here to get a 15% discount.

Japan eSIM with Phone Number, Calls, & Texts

Should you need to get a Japanese mobile number, you will have to visit a local telco 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.

If your trip does not require you to get a Japanese line, you can get this eSIM with a free international phone number instead. It comes with credits for calls and texts and is great as a secondary phone number. Alternatively, you can also get Roamless’ eSIM for Japan. Like Skype, they offer in-app calls to 200+ destinations starting at only $0.01 per minute (no phone number included).

Bestselling eSIMs on Klook

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

• 4G/5G Japan eSIM by SoftBank (Booked more than 100,000 times)
• 4G/5G Japan eSIM by Klook (Purchased over 500,000 times)
• 4G Japan eSIM by Sakura Mobile (Bought more than 20,000 times)

The first option, SoftBank, is the official prepaid eSIM of the telco, while the third option is from a reputable Japanese company. The second option is Klook’s own Japan eSIM, which comes with unlimited data and a very simple one-click installation that is perfect for first-time digital SIM card users.

Top Japan eSIM Providers

Over the years, tourists bound for Japan either purchase 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. 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. To help you, my partner and I created this shortlist of various providers to highlight their best features. We hope this guide helps with your trip planning.

All of their users enjoy in-app calls for only $0.01 per minute and they also have flexible data plans starting at less than $3.45.

Free Trial

If you are on the fence about getting a digital SIM card, how about getting one that comes with a free trial?

GigSky’s eSIM with free data comes with no strings attached, so feel free to take advantage of their offer!

Prepaid eSIM for Japan with VPN

I have personally tried BNESIM’s eSIM with VPN, though for a different country. However, I am able to say that I was able to bypass all restricted sites and felt confident that my personal information remains secure while connected to a public WiFi.

View internet with VPN plans from BNESIM here, or check out Yesim’s data packs with VPN below:

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.

Airalo vs. Ubigi: The Battle of the Most Popular Japan eSIMs

Before you go, take a look at one of the most popular queries related to eSIMs: Ubigi or Airalo? Take time to read on Reddit and reviews on TrustPilot, and you’ll see comparisons for these providers. I have personally tried Ubigi in Japan and was very happy with my experience. Their app was easy to use, and the 5G connection was consistent. Moreover, I have read that they are part of NTT Docomo. Hence, it’s logical that they can provide the 5G internet experience that locals enjoy. (You can book Ubigi eSIMs here with a 10% discount using our code TRAVLISTS).

However, this is not to say that Airalo is the lesser choice. With more than 10 million users, they are a trusted brand in the eSIM space. Plus, their eSIMs for Japan are powered by leading telcos like SoftBank and KDDI. This ensures that travelers get a superior online connection.
