“Nice”

Brofessional

5 out of 5 stars
Japan

“The price is a bit high but the network worked perfectly and the speeds were good. Also the app they have works very well.”

KitanoKen

4 out of 5 stars
Japan

“Much better than I expected for a travel eSIM. The Japan eSIM I bought from Airalo wasn't the cheapest, but latency was surprisingly good (below 40ms) even though the IP address was from USA, which probably means they are doing a local breakout. The speeds were good, more than sufficient for travel needs, and the coverage was also satisfactory.

It would have been the perfect option if the price were cheaper.”

“Great experience. Got the eSIM in a sale. Activated while still at home, immediately got connection after deactivation of air plane mode. Speed was good, coverage OK. One downside: location was sometimes detected as Singapore, which was not always great (Microsoft send me a lot of warnings because it was routed through SingTel Mobile in Singapore). ”

“Very slow even with excellent signal strength (4G, iPhone XS), unusable even for maps and messaging. Very high ping times (600ms+). Support is very slow as well and did not fix the issue nor provide a refund.”

Tommy

1 out of 5 stars
Japan

“Extremely poor support that doesn’t respond to any help after 24 hours.

Paid and activated the sim but couldn’t get any internet connection (despite successfully connected to SoftBank 3G).

I’ve checked many times that apn and roaming is enabled. And re started my phone multiple times.

Issue was never resolved and Airalo support was non existent. ”

“Showing not active all the time, can’t use map, checked settings, trouble shooting, everything is fine, three people bought, nobody’s eSIM works ”

JP

“Horrible speed across the entirety of Japan, feels lile youre locked in 2G/Edge. Tried multiple reboots, changed speed profile, tried different networks, it all is of an incredible poor quality. Not worth your money. Switched to another leading eSim provider, night and day! I now can finally browse.”

Bobber

3 out of 5 stars
Japan

“This is my second time using Airalo in Japan. It works okay but it seems the carrier switching doesn't work perfectly. When that happens I just have to turn on -> off flight mode which is a bit annoying but not too big of a deal.

It connected to au (KDDI) 4G most of the time, occasionally docomo (NTT).

The speed is decent but it's roaming via Singapore so there is a certain latency for sure.
The screenshot attached is the one I did at Narita airport.”

Airalo for Japan FAQ

Does Airalo offer unlimited data eSIM for Japan?

Airalo does not provide a genuinely unlimited high‑speed data eSIM for Japan. The plans that carry the “Unlimited” name supply 3GB of high‑speed data per day; once a user reaches 3GB in a day, the speed drops to 1000kbps, which is noted as the reduced speed in the plan’s features. Therefore, those plans are capped rather than unlimited.

For travellers who need more data, Airalo offers fixed‑data plans. An example is the Asialink – 100 GB plan, which delivers 100GB of high‑speed data for 180 days at $89.00 USD. The Asialink – 50 GB plan gives 50GB for 30 or 90 days, priced at $59.00 and $69.00 USD respectively. These fixed‑data options can be more economical for heavy data usage in Japan.

Does Airalo offer Japan eSIM with phone number and SMS?

Airalo does not offer any eSIM plan for Japan that includes a phone number or SMS capability. Travelers can purchase a data‑only plan and use VoIP services such as WhatsApp, Telegram, or iMessage to communicate, though some destinations may block or restrict access to specific apps, so users should verify that the apps they rely on work in Japan before purchasing.

How many data plans does Airalo offer for Japan?

Airalo offers 17 single‑country data plans for Japan and 38 multi‑country plans that include Japan. These plans range from as little as 1 GB for a few days to as much as 100 GB for up to a year, with prices between $4 and $159. Within these offerings, some plans use a fixed data cap that applies for the entire validity period, while others impose a daily data cap that limits usage each day.
