Spectacular location, but aware: there is a lot of climbing on stone steps on the mountain. Save the legs and take the cableway up, then walk down (which is still tough on the legs after all the climbing you will do even after taking the cableway up). You can always purchase a ticket for the ride down if the legs are toast when it's time to descend. Also try to avoid weekends or holidays as a LOT of people visit the mountain (we went during Golden Week and it was jam packed as you will see in some photos).
