Nankyu Ferry inquiry

Hi

I am planing my visit to Cape Sata then heading to either Kagoshima or Ibusuki.

I heard that there is a ferry that can save the driving time but the ferry time seems to be very limited and i heard that it is limited to 7 cars normally. But has anyone tried it? I can't find the instructions on how to reserve and the schedule of the ferry as well as the cost of them. I can't read japanese at all.
I am planing to take this ferry route:
<Nejime (South Osumi) Ferry ⇔ Yamagawa (South Satsuma)>

Thanks!

Nijime is translated as "Nezo", but it is the error of translation.

To see the vehicle fare, click Vehicle Fare tab.

There seems to be no web reservation system. You can visit the office to reserve as well as by phone. I think telephone call is the only practical method for reservation.

I don't think they understand English, so you may better ask someone who understand you and speak Japanese (maybe a front staff of your accommodations).
