Pocket wifi or other portable Internet option without esim?

We are going to be 2 weeks in Japan and both our phones are Android, meaning the esim is not an option for us.

What pocket wifi or other solutions did you use? Can you recommend a supplier? How do i collect it at arrival or send it back after the trip? How much data is enough for 2 weeks, we are fairly heavy data users.

Flying from the UK.

Thank you!
