10 Best Japan eSIM for Tourists: Unlimited Data & Phone Number

With unlimited data and fast 5G speeds, Ubigi is a popular Japan eSIM among travelers. Pronounced as you-bee-gee, Ubigi is a subsidiary of the leading Japanese telco NTT Docomo. What this means is that you can have the same internet experience that locals enjoy. Purchase Ubigi’s eSIM for Japan here using our 10% promo code TRAVLISTS, or check out SoftBank’s equally notable digital SIM card here.

In a nutshell

  • What are the bestselling eSIMs on Klook? There are two: Softbank and this super affordable Japan eSIM with unlimited data.
  • Is there a Japan eSIM with phone number? Getting a Japanese number typically requires that you show your passport at the shop, so it may be difficult to find an eSIM that comes with local digits. However, if you only need an international phone number (not necessarily issued in Japan), you can also consider getting an eSIM from BNESIM. They have an optional international phone number with affordable voice plans.
  • Need a Japan eSIM with calls? Get Roamless, which offers in-app calls to over 200+ destinations starting from $0.01 a minute. Use promo code TRAVLISTS here to get a $5 credit.
  • 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 or Airalo here to get 10% off.

Using a prepaid eSIM in Japan

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 card except that I did not have to pick it up at the airport. All I had to 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.

Award-winning eSIM brands for Tourists 👑

Let’s begin with BNESIM, which has been awarded the World’s Leading Travel Communications Provider for four years now. Having sold millions of products including pocket WiFi, travel SIM cards, international phone numbers, and VPN, BNESIM was one of the first to launch prepaid eSIMs for tourists. Their Japan data plans are among the cheapest in the market (just a little over $2), which is perfect for budget-conscious travelers. They also have an intuitive app and a referral program, which will help you save on your future trips. If this sounds good to you, you can book an eSIM from BNESIM here with our 30% coupon code TRAVLISTS.

Another recognized provider is Ubigi. This brand was awarded Consumer Champion of 2023 at Mobile Europe for their innovative virtual SIM cards. Ubigi has also been selected by BMW and Ultra X as their official eSIM partner, which shows the brand’s trustworthiness and credibility. Their Japan eSIM data plans are also well-reviewed on Reddit and TrustPilot, making it a true consumer choice. Check out Ubigi’s eSIM here starting at only $4.

Bestselling Travel eSIM 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:

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.

As an alternative, you can get BNESIM’s Japan eSIM here and purchase an add-on phone number with a voice plan (available on the app). You will get an international phone number (US or Canada), which you can use for your trip.

Japan eSIM with unlimited data ♾️

When it comes to uncapped data plans for Japan, there are a couple of options to choose from. These include World eSIM (from the same company as Ninja WiFi), Nomad, Yesim, Softbank, Ubigi, and Klook. All of these providers have plans designed for heavy internet users, digital nomads, and travelers. Check out our table below for a quick comparison:

The most popular Japan eSIM with no data limit comes from SoftBank, which our team at Travlists and Tripcky has used several times when we went to Tokyo, Osaka, and Fukuoka. View top things to do in Tokyo ➜

Japan eSIM with Phone Number & Voice 📞

If 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 you only need to make calls, 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.

Japan eSIM with Free Trial 🎁

If you are on the fence about getting a digital SIM card, how about getting one that comes with a free trial? Providers that offers Japan eSIMs with free trial include GigSky (free 100MB) and Roamless (free 500MB). 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 🔒

When it comes to Japan eSIMs with VPN, travelers have two options: BNESIM and Yesim. Yesim offers travel virtual SIM cards for iPhone users, while BNESIM has military-grade VPN that you can purchase at a minimal fee (If you subscribe to BNESIM’s monthly plans, the VPN comes for free.).

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: 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.

We got the unlimited data plan, so we did not have to worry about running out of data in the middle of the trip. We were also able to connect to NTT Docomo’s signal, which was consistently fast. Unlike other eSIMs, Klook’s digital SIM card can also be installed on the app, so we did not have to scan a QR code. Before purchasing this eSIM we read these reviews from other travelers, and we were glad we chose the perfect eSIM.

SAKU’S TRAVEL CHECKLIST
Aside from getting an eSIM in Japan, check out these travel essentials you may want to book for your trip!

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.
