At one time, Kumogakure was at war with Konohagakure. However, on the day of Hinata Hyūga's third birthday, both villages signed a peace treaty. This treaty was soon revealed to be nothing more then a cover when the Head Ninja at the time, who was in Konoha to sign the treaty, attempted to kidnap Hinata in order to obtain a Byakugan and its secrets. The Head Ninja was killed in his attempt by Hinata's father, Hiashi Hyūga.
Kumogakure denied all accusations, and demanded the dead body of Hiashi as compensation for the death of their Head Ninja. At the request of Hiashi's twin, Hizashi Hyūga, as well as the Hyūga clan and the Third Hokage, who didn't want to lose the heir to the clan, decided to send Hizashi's body instead. This had another advantage, besides saving the life of the Hyūga heir; Hizashi's Cursed Seal would seal his Byakugan after his death, safeguarding its secrets. Although they are not allies, Konohagakure and Kumogakure seem to be on friendly terms now.
