Alternatives to getting a Japan eSIM

eSIM has revolutionised the way we get connected while travelling. As long as you have an eSIM-capable phone, you don't need to stress over finding a SIM card when you land in Japan.

You can purchase and download your Japan eSIM before you even take off.

Airalo Japan eSIM

Airalo is a popular travel eSIM provider and one of our favourites. Airalo offers a range of affordable prices and the process of getting set up with one of its eSIMs is nice and straightforward.

Airalo has 7-day and 15-day expiry options, as well as multiple 30-day expiry plans for those who are going to visit Japan for a one-month stay.

The 15-day expiry plan costs $10 and comes with 2GB of data. Airalo's biggest 30-day Japan eSIM costs $39.50 and comes with 20GB of data.

It's important to note that Airalo travel eSIMs only come with data, so you won't be able to make phone calls, but you can still use the calling and video services built into many chat apps.

Here are Airalo's Japan eSIMs:

Price	Data	Expiry
AUD$7	1GB	7 days	View on Airalo
AUD$10	2GB	15 days	View on Airalo
AUD$13	3GB	30 days	View on Airalo
AUD$18	5GB	30 days	View on Airalo
AUD$27.50	10GB	30 days	View on Airalo
AUD$40	20GB	30 days	View on Airalo

_{Note: Airalo's Japan eSIMs use the KDDI and Softbank 4G networks.}

New Airalo customers can use the code NEWTOAIRALO15 for a 15% discount on any of Airalo's eSIMs. Existing customers can use the code AIRALOESIM10 instead.

Jetpac Japan eSIM

Jetpac is another travel eSIM provider. Similar to Airalo, it has a 7-day expiry plan, a medium 10-day expiry plan and several 30-day expiry options. Jetpac has a greater variety of data options but, with the exchange rate at the time of writing, its plans tend to be more expensive.

As with Airalo and other travel eSIM providers, these plans are also data-only, but Jetpac's plans may provide 5G access in some areas of Japan.

Here are Jetpac's Japan eSIMs:

Price	Data	Expiry
USD$6	3GB	7 days	View on Jetpac
USD$30	5GB	10 days	View on Jetpac
USD$9	5GB	30 days	View on Jetpac
USD$16	10GB	30 days	View on Jetpac
USD$21	15GB	30 days	View on Jetpac
USD$18	20GB	30 days	View on Jetpac
USD$32	30GB	30 days	View on Jetpac
USD$47	40GB	30 days	View on Jetpac

_{Note: Jetpac's Japan eSIMs use the KDDI network.}

SIMCorner Japan eSIM

SIMCorner is a travel eSIM provider with a bigger data options for shorter stays. Its 15-day expiry option comes with 10GB of data compared to 5GB and 2GB offered by the other two providers we've looked at. It also has a plan that lasts for 180-days with 15GB of data which might suit more frequent travellers with lower data needs.

Here are all of SIMCorner's Japan eSIMs:

Price	Data	Expiry
AUD$54	10GB	15 days	View on SIMCorner
AUD$75	15GB	180 days	View on SIMCorner

_{Note: SIMCorner's Japan eSIMs use the Docomo network.}

Alternatives to getting a Japan eSIM

You won't be caught out if you don't want a travel eSIM or you don't have an eSIM-capable phone – there are plenty of other options for getting connected while in Japan.

You could opt for a local SIM when you arrive. Sakura Mobile offers data plans on the Docomo network starting from JPY3,500 (AUD$34.48 at the time of writing) for 5-days expiry with unlimited data.

Alternatively, you may already be signed up to an Australian mobile provider with a good international roaming offers. Telstra, Optus, Vodafone, Belong, amaysim, Boost Mobile, felix mobile, and more all have good options for customers who want to use their phone overseas.
