Journey Japan eSIM Avis 

I used the esim in November 2025. No issues with the connection, speed or similar and the price was good. Data was enough for a one month trip. The only issue was that I could not get any text messages or calls through to my number after activating the esim but it was probably my own fault for not understnding instructions/making a mistake in setting it up.

Easy to buy and use.
My phone somehow messed up the installation and I had to add information manual, luckily I could find this information in the guide while using the wifi on the limousine bus. Within 10 minutes I was able to use the eSIM correctly.

Had no issues buying or enabling the eSIM, all pretty straightforward. The connectivity itself was solid, though it was 4G all the way. I had an odd issue where after loosing connection completely (in some remote areas like Magome trail) the network would not reconnect until I switched to flight mode and back, but that might be the phone acting out as my partner did not have such issue with theirs JJ eSIM.

Stellar connection even in the most remote parts of Hokkaido. Highly recommend.

Super easy to install and worked perfectly for my 2 week trip in Japan in multiple locations! Also included a discount at the L.O.S.T bar and other things which we used while in Japan 😁

I might have already reviewed this lol, but yes, just buy it and use it. We trusted the product, bought it, and it worked great.

I had not travelled outside the uk for a very long time, so was nervous about sorting an esim. I was absolutely delighted that i used the journey japan esim. It was very easy to purchase and download. The instructions were perfect for a total amateur like me. I was able to activate it as soon as the plane stopped moving and i had perfect coverage everywhere for my whole trip. Will definitely use it again!

Took two because we stayed for 45 days in Japan :) Never lost signals and we got plenty of bandwidth. I was traveling with my partner and he bought it too. Even deep in the country side, always good signal!

I have used the Journey Japan Esim for almost 5 months straight now. I am abroad in Japan for school and my Tmobile/Softbank sim just wasn't cutting it...
With the JJESIM, I can watch as many videos as I want, quiclly translate phrases, get accurate real time instructions from Google maps, and communicate with my friends quickly. Anything you would need the internet for, you can do with JJESIM.
I chose the JJESIM because Abroad in Japan produces the highest quality "living in Japan" content I've ever seen and I love it. I chose to trust the maker of this Esim and I have NOT been disappointed. Even when I am in an underground bar in a rural city, I have data/service thanks to the JJESIM. Its done better than my American Sim does back in USA! I highly reccomend the unlimited plan.

I bought 20gb each for me and my brother for our Japan trip in the summer, we activated our esims with no problems as soon as we arrived at Haneda airport and it really helped make our trip smooth, keeping us connected at all times whether we were navigating the busy streets of Tokyo or answering video calls with family on our way up to some hidden shrines in the countryside, I can’t see us using anything other than JJ eSim on future trips.

Worked exactly as described. No problems at all. Easy to install and did not notice any loss in coverage.

Simple to activate and easy to use, Data coverage was occasionally spotty and slow. I went for 2 and a half weeks on my first trip to Japan, travelling various locations on the golden route and off it. Despite having chosen an unlimited data plan it really didn't *feel* so unlimited as I noticed measurable slowdowns past a certain point in the day seperate from how busy it was around me. Also, if you expect to go to rural areas, As I spent a day in Kinchakuda, Saitama, don't expect your data to not cut out.

I made 2.5 week journey, mainly focused on Kyushu region. Installation and taking the eSIM into use were quite effortless. Overall the eSIM worked fine.
There were some connecting issues once in a while in 'more remote places' such as Yufuin village, Kagoshima and Beppu. Also crowded locations (hotels (using wifi is better), Dotonbori, etc.) slowed down the connection quite a bit.

Hello team,
I used the 20g esim for my 2 week trip in Japan. I had no performance issues, no dramas using what's app to contact family, played heaps of pokemon go and still had heaps of data remaining when I left. Highly recommend and the service team are quick to sort out any problems if they arise.
Thank you.

I visited Japan in 2024 and with no knowledge of what products were available for data there, ended up spending more than £200 on small roaming data packages from my provider.

During 2025, I learned of Journey Japan eSIM, and bought the 50GB package before going away on this year's trip - at $49, or about £36, less than a fifth the price of what I spent last year.

If that alone had been the benefit it would have been worth it, but it was also faultless for the three weeks I was travelling. Great coverage, fast data, and totally reliable. Easy to set up too - I just switched from my existing eSIM to the JJ one when I landed, and it connected to the network immediately.

Several friends are going to Japan in 2026, and I will be recommending Journey Japan eSIM to all of them.

Very easy to install and use. Was also very affordable. Chris Broad put his name on this product because it's actually good. I had never trusted eSIMs and always went with the physical SIMs until this year, and was pleasantly surprised to see how easy it was.

My one suggestion for anyone using it is to purchase slightly more data than you expect you'll need -- we underestimated how much we needed, but our hotel turned out to have bad wifi, so that ate into our data usage a lot. But It was easy for us to top-up our data via the eSIM website.

Easy to set up and no issues with coverage in Tokyo, Kyoto or Iseshi. When I visit next year I’ll definitely be getting another Journey Japan eSIM.
Thank you to Chris Broad for suggesting this one.

We visited Japan in September and I got a $50 plan for my wife and myself and it easily covered all our requirements for travelling around Japan. We went to out of the way places and tourists and it all worked fine. I’d highly recommend getting The in the travelling man in Japan thanks guys for a great trip cheers Dean.

Easy setup, great connection everywhere. Didn't once have to worry about running out of data, or not being able to connect. Would definitely use again!

This was my first time using an eSIM while traveling throughout Japan. Previously I used pocket wifi, but on my last trip the pocket WiFi company mailed me a locked device. I decided to do eSIM after that issue for less hassle and stress. The whole process was great. No standing in line at an airport to pick up a device, no need to continually charge another device, and full coverage everywhere I traveled.

The moment I switched my phone over to the eSIM, I had fast, reliable data for the whole trip. I traveled from Tokyo, to Hiroshima, matsuyama, imabari, and several other places without any drop in service. I plan to use this eSIM again on my future trips. 10/10 would recommend
