The Mountain Summit is located high in the mountains surrounding Yukumo Village. The only monster found here is Amatsumagatsuchi. The sky in this area is blood red, with swirls of grey and purple. Roaring mountain winds can be heard at all times.
Players can man the four Ballista in the Area; this is by far the easiest way to break Amatsumagatsuchi's back. Players are also able to gather Ballista Ammo from various boxes on the ground. Power Seeds are also found in the area.
- Flowers in the area can be gathered to get some Herbs or Cure seeds.
- Remains that resemble broken boxes have Ballista S if gathered.
- The giant log can be broken by Amatsumagatsuchi when it attacks it, but only a portion of it is broken
- If you look around you will see the fallen parachute of a hunter and a member from the Elder Dragon observation center that tried to observe Amatsumagatsuchi. The parachute was destroyed as seen in Amatsumagatsuchi's Ecology video.
- When Amatsumagatsuchi is still alive the area seems to resemble chaos and despair. But when the storm fades away the are is actually very beautiful and scenic and looks like new hope will start again.
