Great experience in Tokyo. Perfect combination of experience and a memento to go with it for remembering your trip. We did it with three kids, the youngest (11) needed some minor help but the staff spoke decent English and were very helpful.
I would suggest making a reservation, we went within an hour of them opening and were able to squeeze into a time slot but they were mostly booked through the week.
Plan for around an hour or so of commitment time, maybe longer if it's crowded.
