Avoid paying high fees and roaming charges to stay connected in this country, and get an eSIM for Japan instead!

It’s easy to buy it online. The best thing is that you can top up anytime if you need more data.

There are a few reasons why you should choose an eSIM for Japan.

Choose an eSIM Japan Data Plan that suits your needs

Depending on how long you plan to travel in Japan and whether you will be using Wi-Fi service when possible, these are factors that will determine what eSIM for Japan you should choose.

If you plan to use wifi during your travels in Japan (hotels or restaurants may offer this option free of charge), then you might want to go with a smaller plan, 1GB for $4.50, valid for 7 days, or 2GB for $6.50 for 15 days.

Alternatively, if you primarily rely on phone coverage for your data, you might choose a data plan that includes more data. I’d recommend this 10GB eSIM data pack for $18, valid for 30 days or the largest plan, 20GB for $26 for 30 days.

Should you need more, top up online within seconds using the Airalo App.

eSIM Japan – How much does it cost?

The best eSIM carrier for Japan is Airalo. Currently, Airalo offers two great options to stay connected in Japan, and really, that’s all the choice you need. The combination of price and the best coverage makes Airalo Japan eSIM an easy (and convenient) option.

Whether you’re travelling in Japan independently or have chosen to explore with Wendy Wu Tours or G Adventures, two of the best tour operators, stay in the loop with an eSIM for Japan.

Convenience is the key with prepaid eSIM for Japan

Nothing is more convenient than landing at your destination and instantly connecting to the local carrier.

For travellers, this means instant connection to order a taxi or ride via a ride-sharing app from the airport. Furthermore, you can immediately access Google Maps to follow navigation and reserve that last-minute hotel room in Japan on Booking.com.

Getting organised and downloading eSIM for Japan before arrival will benefit you greatly. If you’re still wondering what an eSIM is and how it works, this post will explain it in plain English.

Sometimes, Japan isn’t the easiest of countries to navigate with the language barrier. In saying that, I believe Japanese people are the most polite nation on earth. They will go out of their way to try to translate or help you in any situation.

Having access to knowledge and tools online (from your handheld device) is priceless for reducing any stressful and lost-in-translation situations you may encounter in Japan. 

ESIM for Japan and eSIM for all international travel – The future of staying connected

eSIM for Japan offers the lowest rates available for data; furthermore, the data packs are easy to get onto your device. 

Simply download the Airalo app, purchase the right data package and follow the steps to activate the eSIM for Japan before you arrive.

Important: Your device must be compatible with eSIM. Please check this list to see if your device supports eSIM before purchasing an eSIM for Japan.

A Few Tips: 

  • Before arriving in Japan, switch from your current mobile provider to the Japan eSIM provider. Don’t worry; there is a step-by-step guide on how to do it during installation.
  • Most importantly, once your eSIM card is activated, turn off data for all apps you don’t use and those who can use a lot of data. Apps such as Instagram, TikTok, and Netflix will eat up your data fast, so don’t access that until you reach your hotel and access the free wifi. 
  • And, if you want the freedom to instantly send those videos home to friends and family of you chowing down on the best Japanese snacks on that Kyoto Foodie Night Tour or the highlights from your Bar Hopping Night Tour in Shinjuku, Tokyo, the best eSIM for Japan works like a dream. 

And as I mentioned before, it gives you the option to buy more data within seconds, should you reach your data limit.

You can always top up your eSIM for Japan, no problem

Japan is an exciting destination, that is for sure! Perhaps you will spend all your data on your Japanese eSIM much quicker than you planned. No problem; you can select your current eSIM for Japan and top up online.

Get online on wifi, go to the Airalo website or App for eSIM for Japan and buy more data. It’s too easy.

Is eSIM for Japan the cheapest way to stay connected? 

Travelling to Japan, you can purchase a local SIM card at any major airport or phone store. 

Of course, this allows you to make calls and send text messages within the country where you purchased the SIM card. It will also give you access to data and local calling rates.

I know the latest price to get a local SIM card in Japan starts at about $18 for 1GB. You must provide your passport and details to register this local SIM card for Japan. 

So, in the end, eSIM for Japan wins again. It’s like a Japanese bullet train, hard to beat!

Keep your initial SIM card in your phone

Another bonus of downloading an eSIM for Japan is that you do not need to remove your physical SIM card. eSIM is digital, so it’s all encrypted inside your phone.

It’s great news because you won’t risk misplacing your tiny SIM card (as you’ll leave it inside your device); it also means you can receive your messages from home.

Another plus (I told you there are many) is that once you buy the eSIM for Japan, you can navigate the Airalo app in English.

So there you have it – The eSIM for Japan is the obvious choice for staying connected.
