Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The internet is okay, but the signal is weak in some areas in Kyoto. We bought 2GB per day, but it wasn't enough. Every day, it runs out at 5 PM. After it runs out, it's incredibly slow, making it almost impossible to do anything. If you're using it a lot to browse maps, use Instagram or TikTok, I recommend 5GB per day. It's better to have some extra than not enough, because it can be really difficult to search without internet.

I purchased an 8-day eSIM, and it was stable throughout my trip to Fukuoka, including visits to Ito-majima and Dazaifu. It automatically switched to 5G when there was a 5G signal and 4G when there wasn't. The only time I encountered a very weak signal was in a basement restroom in a shopping mall; it was fine once I left, which was due to the mall's antenna coverage and not related to the eSIM. I installed the eSIM in China the day before departure. During installation, it might show an activation failure message, but that's normal. Wait until you can access the eSIM card and then turn it off. Once in Japan, activate it again and switch your cellular data to eSIM. It uses a local IP address, so you don't need to enable data roaming. You can also create a hotspot. The whole experience was smooth, and the price was reasonable. Highly recommended!

The eSIM I used during my trip was very affordable, especially after discounts and promo deals — it became incredibly cheap. I had zero issues using this eSIM throughout Japan. The connection was stable and reliable the whole time. I would definitely use this eSIM again on my next trip to Japan. Totally worth it. If you’re still unsure, don’t worry — this eSIM is one of the best choices you can make.
