We got to the Oike pond car park at 4:30am and rested a little until sunrise before setting off to hike Hiijidake. The trail is not too difficult but does involve climbing higher than most trailheads at Kuju. A Utongoshi mountain pass we found Hiijidake covered in bright pink flowers. It is a wonderful thing to see and is very beautiful.
After coming down we went to visit Oike pond a small pool with beautiful blueish water. From there we went to Meisui waterfall which involved climbing over many fallen trees and ignoring lots of keep out signs. The water was raging and had the same blueish tint.
