According to Ancient Japanese Mythology, the very first Emperor was named Jimmu. He was a Demi-God who made war on the many Clans and their Leaders in Ancient Japan, to united them into The Imperial House of one Ruler – or Jimmu. Said to have lived in the 6th Century AD, - Jimmu was said to have superhuman abilities and strength. He could not be defeated in battle, and could slay any Enemy with a single blow from His weapon. His archery skills were such that one of his arrows could (when shot), ''fly for days''. Upon unifying Japan, Jimmu would die. Some versions state He ascended back into The Heavens and others that He is entombed on Mount Unebi, in Japan.
