Scenic ride but not great if you can't understand Japanese

I booked this night drive from the US for a group of 11 people. Upon booking, I received a confirmation email that showed the directions to get to the location, which was very clear, as well as an explanation that the tour guide was Japanese but there was going to be a GPS Multilingual Guide System for non-Japanese speaking people.
I assumed when we checked in, we would be given that device, or at least directions on how to obtain them, but they just told us to get in line for the ride. The tour started, and the tour guide was talking in Japanese. I asked about the multilingual system, and she scrambled to get them but realized there weren't enough. so we had to share a few of them. That wouldn't be a problem if the earphones actually worked. both of them only had audio in one side and nothing in the other. So I was explaining everything I heard for my son, and my husband did the same for our daughter.
Aside from that, it wasn't really a full translation of the tour. The tour guide was talking pretty much the entire time, but during the 1 hour trip the system only explained 4 or 5 locations that maybe took 1 minute each! We enjoyed the ride but felt pretty that we could've learned way more.
