Lockers Ishigaki

Hi, have a bit of particular question about lockers at Ishigaki. I would like to know if the lockers at the bus terminal (or alternatively, the ferry terminal) allow me store my luggage for three days.

Nobody?

Never been there, unfortunately.

Out of curiosity I checked on Google Maps, and someone posted a photo of a notice paper. You can apparently use the coin locker for up to 4 days before your luggage gets collected.

Thanks, very clear!
