The island was ruled by the Shandians four hundred years ago, who guarded the Poneglyph located in their city of gold, but they too were launched into the sky.
In present day, however, the island is mostly uninhabited other than a few towns. The island seems to be a major base for pirates, one of which is Mock Town.

On the West side of the island lies the port of Mock Town. Other locations seen on the map are Mouth Bay and South Grave.

Mock Town is a port of Jaya. It is inhabited mostly by pirates, despite it looking like a resort.

Pirates who dwell here tend to judge their level of skill and power based on their assigned bounties, meaning those carrying bounties above average (10,000,000-20,000,000) are often respected more by the citizens. The town itself is built on the money that the pirates spend inside it freely. For that reason alone, though fighting does occur in the town, the pirates rarely attack the people living there.
