Very happy. When I arrived in Tokyo I couldn't activate my eSIM because of a mistake on my end. I contacted PlanJapan on WhatsApp. Quick, efficient reply. Thanks a lot. No hesitation in recommending them.

The SIM worked perfectly. You just need to remember to turn on data roaming for that SIM before you land in Japan. It runs on the docomo network, one of the best in Japan. I got one for myself and my whole family for the trip. Highly recommended.

Extremely happy with this eSIM, I highly recommend it. I visited several cities and never had a single network issue, and unlike other eSIMs you don't need a VPN. I personally found the price unbeatable. Excellent after-sales service too.

I used the unlimited eSIM for 15 days. Nothing to fault — I was also able to reach the team easily about a slow connection and everything was sorted out quickly.

I go to Japan twice a year and every time I get my eSIM from PlanJapan. The network works from the north to the south of the country, even in remote corners. The prices are very good for the quality of service — I hope they stay that way.

Very responsive customer service and an eSIM that works perfectly everywhere, even in the Japanese Alps. I had a problem when I landed in Japan — my own fault — and they helped me straight away. Thank you so much!

I bought it for my two weeks in Japan and it's very easy to install, with a great network and speed over there. I recommend it 100% and I'll come back to you when I return!

I hesitated for a long time, there are so many eSIM options for Japan! I went for the 15-day unlimited plan: everything was perfect, both for Google Maps and for social media. I'd do it again without hesitation, thank you so much

Very happy with the network, I had no connection problems and could access all my social media. I took the 10 GB plan, which was more than enough for 10 days using the internet all day, every day.

Brilliant eSIM that never let me down! I had great reception everywhere in Japan and even had TikTok! I recommend it — €35 for 50 GB for a month, I couldn't find better.

My first experience with an eSIM and I recommend it. I activated it as soon as I landed at the airport and it worked perfectly until I left Japan on 05/12/25.
