Rent a car from Koyasan

Hi,

My wife and I are visiting Japan in October for a few weeks and we were planning to spend a night in Koyasan before renting a car to go to Nachikatsuura and then leave for Osaka by train a few days later.

Do you know if there are rental companies in Koyasan? And do they allow leaving the car in a different place from where you rented it?

Thanks a lot for the information.
