I have used a Pocket WiFi device in Japan on previous trips, especially when I wanted to be online without interruptions all day. It was reliable and did what I needed at the time. There was no need to worry about whether my phone would work on local networks, and having one connection available at all times felt reassuring while moving between cities.

Being able to share data across several devices is useful, and it avoids any concerns about phone compatibility or setup. Pocket WiFi can make sense when traveling in a group. But after testing more options, I usually find eSIMs to be the better choice, especially for solo trips where simplicity matters more.
