|Located In||First half of the Grand Line|
Jaya (ジャヤ Jaya) is a forest-covered spring island that was once shaped like a skull and much larger than it is now. Due to over half of it being launched into the White-White Sea by the Knock Up Stream, only the part that makes up the skull's mouth remains.
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. This is the location of the Jaya Arc. For more information, see Upper Yard.
