I'm an iPhone 14% user. As soon as I arrived in Japan, I wanted to activate my mind, so I needed a Wi-Fi connection, so I sat in the bathroom on the way to find my luggage and connected it with airport Wi-Fi. I can't use it, so I'll wait, and I'll find my luggage and go to Rapid. ㅎㅎㅎ The speed is fast and good~!!!

Overview of Japan eSIM Plans for Tourists

Trip.com Japan eSIM

Okay so I literally spent ages comparing like every Japan eSIM out there (there are SO many!) and Trip.com's deals are actually insane! Here are some of my faves:

  • 3 days (1GB/day): $1.94
  • 5 days (1GB/day): $3.02
  • 7 days (1GB/day): $4.09
  • 15 days (1GB/day): $8.25

But wait - there's literally a plan for EVERYONE. They've got:

  • Daily data options: 500MB, 1GB, 2GB, or even 100GB (like who needs this much but ok 😂)
  • Fixed data packages: from 3GB all the way up to 50GB
  • Different durations: 1 day to 30 days (even random ones like 8 or 12 days!)

I went with these because:

  1. Stupid cheap compared to others (saw some charging $20+ for the same thing lmao)
  2. Connection is actually very reliable - works everywhere in Japan
  3. Setup takes like 2 mins max with a QR code (can do it while waiting for bags at the airport!)
  4. Running on 4G LTE so all your apps work smooth - Google Maps, Insta, TikTok, whatever. No more hunting for WiFi or selling a kidney for roaming fees!

Mobal eSIM Japan

  • 1GB data for 8 day = $12.67 USD
  • 100GB data for 31 day = $52.39 USD

Sure, Mobal's running on Docomo's network with decent speeds, but Trip.com's 4G LTE coverage is just as good everywhere in Japan. Plus you don't have to wait around for emails - Trip.com sends your QR code instantly (we love that for setting up at the airport!).

Okay so I HAD to check out more about Mobal since everyone talks about them for Japan eSIMs... and girl, I was shook at their prices! They're charging $12.67 for just 8 days with 1GB data?! And their "big" package is $52.39 for a month of data. I mean... what?

Meanwhile Trip.com over here is literally giving it away - $4.09 for a week with 1GB daily data. That's like a third of Mobal's price! Even their two-week plan is only $8.25. Make it make sense!

Look, I'm just saying... why pay extra when Trip.com is right there? Save that money for more sushi! Trip.com - periodt! 💅

Airalo eSIM Japan

  • 1GB data for 7 day = $4.50 USD
  • 2GB data for 15 day = $6.50 USD
  • 3GB data for 30 day = $8.50 USD

Okay bestie, let me spill about Airalo real quick! They're running with SoftBank (fancy!) and their prices look cute at first - $4.50 for a week with 1GB total, $6.50 for two weeks with 2GB total, and $8.50 for a month with 3GB total.

BUT WAIT-

Did you catch that? It's total data, not daily! 😱 With Trip.com you're getting 1GB EVERY DAY for basically the same price ($4.09 for a week). Do the math - that's 7GB vs Airalo's 1GB for almost the same money!

Like, imagine trying to survive Japan on just 1GB for a whole week? One TikTok session at Shibuya Crossing and you're done!

Sure, Airalo's got that SoftBank connection and yeah, their setup is pretty quick with the QR code thing (but so is Trip.com tbh). And yes, their streaming works fine... until you run out of data on day two!

Look, I'm all for options, but Trip.com is giving us SO much more data for basically the same coins. Plus their coverage is just as good across Japan.

Sakura Mobile

Sakura Mobile is another option for visitors to Japan, popular among both short and long-term stays. They also offer eSIMs with prices based on the duration of stay (up to 90 days) and data usage. Their cheapest option is a 3-day, 1GB eSIM for $17.96. Sakura Mobile uses Docomo as their main provider, ensuring good coverage throughout Japan.

Activation is simple, with customers receiving a QR code via email. Despite being more expensive, Sakura Mobile had the slowest performance among the eSIMs tested, with an average download speed of only 7.9Mbps.

Ubigi Japan eSIM

  • 500MB/day data for 1 day = $2.57 USD
  • 50GB data for 30 day = $64.02 USD

Ubigi serves as a worldwide eSIM provider, catering to more than 200 destinations globally. Despite being a newer entrant in Japan's eSIM landscape, Ubigi offers a broad spectrum of plans, ranging from cost-effective daily options with 500MB of data at approximately $2.57 USD to more substantial month-long offerings that include up to 50GB of data for about $64.02 USD, meeting a wide array of travel requirements.

The process of acquiring an eSIM from Ubigi is straightforward. Payment completion is quickly followed by the receipt of a QR code via email, facilitating immediate activation. Ubigi partners with NTT Docomo, ensuring expansive and reliable network coverage across Japan, backed by Transatel, a subsidiary of NTT.

In evaluations, the 3GB Ubigi eSIM provided dependable connectivity, with average data speeds reaching 73.72Mbps

SoftBank eSIM

SoftBank eSIM is powered by SoftBank, one of Japan's major carriers. They offer data-only plans for different durations, with options for unlimited 4G data or a daily allowance of high-speed 4G data. The prices vary depending on the plan chosen. While SoftBank eSIM offers stable and fast internet, there may be compatibility issues with certain phone models and a waiting period before activation.

What's Best for japan? eSIM, SIM and WIFI

What's Best for japan? eSIM, SIM and WIFI

If your phone supports eSIM (most newer phones do), just go for that! It's way less hassle - no tiny cards to lose, no devices to charge, and no awkward airport counter conversations. Plus Trip.com's eSIM prices are actually ridiculous (in a good way).

But if you're traveling with a squad or your phone doesn't do eSIM, pocket WiFi or regular SIM cards are still solid options. Just pick what works for your situation!

OptionKey ThingsDownsides
eSIM- Basically a digital SIM card, no physical card needed
- Setup is easy (just scan a QR code and you're done)
- Works the second you land
- Gotta check if your phone can use it first
- Can't get a Japanese phone number
Regular SIM- Just a tiny plastic card you pop in your phone
- Tons of plans to pick from
- No charging needed
- Your phone needs to be unlocked
- Kinda annoying to set up (where's that tiny pin thing when you need it?!)
Pocket WiFi- Great if you're traveling with friends/family
- Can connect multiple devices
- Ready to use when you pick it up
- Need to keep charging it
- Dealing with pickup and return
- One more thing to carry around

From now until stock last, you can enjoy up to 8% off hotel deals on Trip.com when you register as a member on desktop or app!

I was able to get the QR code immediately after purchase and set up the eSIM on the same day. I traveled from Osaka to Nara, and the coverage was good. I will buy it again.

3 Benefits of Using Japan eSIM

3 Benefits of Using eSIM in Japan

1. Can be used immediately upon arrival in Japan

One of the major benefits of eSIM is that you can have internet access smoothly from the moment you arrive at the airport in Japan.

With traditional SIM cards, you would need to purchase them at the airport shop or receive a SIM card that you pre-ordered. However, with eSIM, you can download it in advance and connect to the network as soon as you get off the plane. This allows you to efficiently arrange for taxis or navigate your way to the hotel, making your trip more convenient.

2. No risk of loss or damage

Traditional SIM cards are very small and require careful handling. Especially when replacing them during your trip, the risk of loss or damage increases.

On the other hand, eSIM is not a physical card, so you don't have to worry about losing or damaging it. There is no need to go through the hassle of opening the SIM tray with a small pin or worry about accidentally dropping the SIM card.

3. Dual SIM capability

By utilizing eSIM, you can use dual SIMs. Dual SIM allows you to use two networks on one smartphone.

This means you can have a SIM card that can be used in Japan and another one for overseas, allowing you to smoothly switch network environments when traveling between Japan and other countries. With dual SIM, you don't have to go through the hassle of contracting for internet access every time you visit multiple countries.

3 Drawbacks of Using Japan eSIM

3 Drawbacks of Using eSIM in Japan

1. Limited device compatibility

To use eSIM, you need a smartphone or tablet that supports eSIM. While newer models are becoming compatible with eSIM, older models or some mid-range to low-end devices may not support eSIM.

This means you will need to check whether your current device can use eSIM, which can be an extra step. If you need to purchase a new device to use eSIM, you also need to consider the associated costs.

2. Cannot be used on multiple devices

Traditional SIM cards can be switched between devices. Therefore, you can use one SIM card on multiple devices. However, since eSIM is embedded in the device, it is difficult to easily move it between multiple devices. Therefore, if you want to use multiple devices during your trip to Japan, it may be inconvenient.

3. Cannot use a phone number

With eSIM data plans, you may not be provided with a unique phone number or may require an additional fee. This may cause inconvenience in situations where a local phone number is required, such as making restaurant reservations or contacting hotels.

Traditional SIM cards often provide a phone number along with data communication, so this is an important consideration when considering using eSIM.

3 Tips for Choosing Japan eSIM

3 Tips for Choosing Japan eSIM

Listen up! After trying different eSIMs in Japan, here's what actually matters when picking one:

1. Check Those Daily Data Limits

Here's the thing - some providers try to trick you with "total data" amounts. Like, 2GB for a week sounds okay until you realize that's ALL you get! Look for daily data limits instead.

That's why I love Trip.com's plans - you get 500M/Day, 1GB/Day, 2GB/Day, or even 100GB/day EVERY DAY. You'll need more data for Google Maps, Instagram, and looking up what that mysterious vending machine drink actually is!

2. Coverage is Everything

You know what's worse than no internet? Spotty internet. Some cheap eSIMs only work in big cities, leaving you stranded once you venture out. Make sure your eSIM works everywhere in Japan.

Trip.com runs on major networks, so you're covered from Tokyo to that random ramen shop in the countryside. No more "no service" anxiety!

3. Price vs Duration Sweet Spot

  • Hot tip: Don't just grab the cheapest plan! Think about your whole trip:
  • Weekend trip? A 3-day plan might be perfect
  • Two-week adventure? Get a 15-day plan (way cheaper than buying multiple short ones)
  • Not sure about dates? Trip.com has flexible options from 1-30 days

Bonus Tip: Get your eSIM before you fly! Nothing worse than trying to figure this out at the airport while jet-lagged. Just scan that QR code while waiting for your bags and you're good to go!

Frequently Asked Questions about Using eSIM in Japan

  • 1.How to download and use eSIM after purchasing?

    The system will send the QR code to your email to download the eSIM, after you purchasing.
  • 2.What should I do if I cannot receive the email to download the QR code?

    Please contact customer service to resend the QR code.
