Are you gearing up for a winter trip to Nagoya,
Japan's rising star destination, even hotter than Sapporo these days?
Before you jet off to Nagoya, there's one essential you absolutely need for your Japan trip:
an eSIM.
Today, I'll share everything you need to know about my top recommended Japan eSIM,
including how to book it with a 50% discount and my experience using it for unlimited data!
For Your Japan Trip, We Highly Recommend an eSIM!


When you're exploring Japan, you'll definitely be relying on apps like Google Maps, Papago,
and GPT. That's why having smoothly flowing, reliable data is incredibly important.
Especially since taxi fares in Japan can be quite pricey, most travelers use Google Maps to find the best routes and public transport options. If your data connection drops,
you'll waste a lot of precious time, which can really diminish your travel experience.
That's why I, who travels to Japan about once every two months, always opt for an eSIM.
📌 Let me share a few reasons why I choose an eSIM over other options.

✅ First off, as I'll explain more below, eSIMs are incredibly simple to use.
Unlike traditional physical SIMs, you don't need to remove any card; you can install it with just a few taps.
It might feel unfamiliar if it's your first time, but after just one use, you'll have it set up in under a minute.
Even my parents, who are older, have become pros at installing eSIMs!

Next, as I mentioned before, since an eSIM allows you to keep your existing physical SIM installed,
✅ you can still receive calls and texts from your home country.
For those working professionals, isn't it stressful to miss urgent calls from work?
With an eSIM, even when you're abroad, you can stay connected and travel with complete peace of mind.

Finally, a huge advantage of eSIMs is that
✅ they are more affordable than other data roaming options.
I personally love streaming OTT content and long-form videos, so I always opt for unlimited data.
With an eSIM, I can enjoy all of this without worrying about the cost, making it incredibly convenient.


However, the only slight downside of eSIMs is that
they can only be used on specific devices. While most newer models are compatible,
make sure to check if your device supports eSIM before booking!

Now, let's dive into the Japan eSIM I personally recommend!

eSIM Prices, Capacity
Next, I'll share the eSIM prices and recommend data capacities
for those using it for the first time.
Most trips to Japan are planned for around 4-5 days,
so I'll introduce options based on a 4-day trip.
Below, I've summarized the discounted prices by data capacity
and recommended users in a table.
Category | Price | Recommended for |
Unlimited Data | ~$15 → ~$8 | Those who want to use data without worries (frequent video streaming, OTT) |
5GB Daily | ~$12 → ~$6 | Watching long-form videos, YouTube |
4GB Daily | ~$11 → ~$6 | Watching short-form videos |
3GB Daily | ~$9 → ~$5 | SNS usage, simple photo uploads |
2GB Daily | ~$7 → ~$3 | Using only maps, search, KakaoTalk |

First, for those who, like me, enjoy streaming OTT even when traveling and staying at hotels,
I recommend not hesitating and opting for ▶️unlimited data.
You won't have to fret about how much data you've used,
and you won't need to rely on hotel Wi-Fi, so there are no security concerns either!

However, for those who don't use their phone much and only rely on
Google Maps, search, and KakaoTalk, ▶️2-3GB daily should be sufficient.
And if you occasionally watch short-form videos, ▶️4-5GB daily is also a great choice.
Since there's currently a promotion running and the price difference between capacities isn't significant,
I hope you choose a generous data plan!
Now, let's move on to my MySIM usage review
from my trip to Nagoya.
MySIM Usage Review: Nagoya Trip

I tried MySIM, which was recently launched by MyRealTrip,
on my recent trip to Nagoya as soon as it came out.


I used the MySIM unlimited data plan, and I could connect right after my flight landed,
so I quickly figured out how to get to the city center.
Thanks to MySIM, I was able to travel safely to my accommodation
in downtown Nagoya and even complete check-in!

Also, when you go to Nagoya, a must-visit nearby destination is Shirakawa-go.
Even though it's a rural area, the data connection was just as strong and uninterrupted as in the city.
Best of all, the data worked perfectly even on the bus during the tour,
allowing me to watch OTT content and make the travel time much more enjoyable!

Japanese restaurants often have menus without pictures, which can make ordering quite difficult.
In such situations, I use Papago for translation, and the eSIM worked flawlessly even in underground restaurants,
allowing me to translate and order instantly!

Also, when shopping at Don Quijote, there are so many different kinds of souvenirs that it's hard to decide what to buy.
With the eSIM providing a strong data connection, I could search immediately and shop efficiently, which saved me a lot of time!
Today, I wanted to recommend a Japan eSIM
I've just introduced you to the amazing world of eSIM.
And guess what? There's currently a fantastic promotion
where you can book it at half price, so make sure to take full advantage of it
and book in advance to prepare for your upcoming travels!
