Nīas (Indonesian: Pulau Nias, Nias language: Tanö Niha) is an island off the western coast of Sumatra, Indonesia. One of Nias culture that still exists is the Stone Jumping, or locally called Fahombo.

From the age of 10, boys on the Indonesian island of Nias prepare for their stone jump. The stone jump was a ritual taken very seriously. Boys leapt to their adulthood, dressed in warrior garb, signifying that they were ready to fight and assume the responsibilities of men.

The stones that must be skipped in the form of building a pyramid-like monument with a flat upper surface. The height is not less 2 meters, with a width of 90 cm, and 60 cm length. The jumper is not just have to cross a pile of stone, but he also must have a technique such as landing, because if he landed with the wrong position can cause muscle injury or broken bones.

In the past the top of the stone board is covered with spikes and sharp pointed bamboo. Tactically, this stone jumping also means to train young warrior to clear the wall of their enemy with a torch in one hand and a sword in the other hand at night.
