Lockers at Kagoshima terminal for Okinawa

So I'm talking about this one:

Does anyone know if there are coin lockers there? Preferably ones that fit a medium sized suitcase.

I already know of the coin lockers at the Sakurajima terminal, and ones at Kagoshimachuo station, but since I'm taking the ferry to Okinawa, I'm trying to store my suitcase as close to the departure gate as possible, before I go and kill some time before the ferry departs later in the day.

Flip to the coin locker tab to see what is available.

I'm not seeing anything closer. Is there a way for you to contact whatever operator you are getting transport from to ask them directly?

I called the Kagoshima Regional Development Bureau Construction Department, which manages the Amami-Okinawa Ferry Terminal, and asked them. The following is the answer.

There are no coin lockers at the Amami-Okinawa Ferry Terminal. However, there is a baggage storage service. This service is available from arrival to departure. Specifically, from 8:00 in the morning until 17:30 in the evening, a lady in charge is next to the ticket office on the third floor, so please speak to her. She can communicate in English.

Below are some images from my search.

You can barely read that it says luggage storage on the 3rd floor.
