Map

A Map (ナビマップ) is an item that unlocks the mini-map for a world or an area within a world. Although maps only appear in Kingdom Hearts II, Kingdom Hearts Birth by Sleep, Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage-, and Kingdom Hearts III, the minimap feature is also present in Kingdom Hearts 358/2 Days, Kingdom Hearts Re:coded, and Kingdom Hearts 3D: Dream Drop Distance, and is automatically unlocked from the start of the game. Maps are mostly found in large treasure chests, but some are automatically obtained after certain events. Instead of being stored in the "Items" menu, maps are listed in the journal.

Kingdom Hearts Birth by Sleep
In Kingdom Hearts Birth by Sleep, all Maps are simply called Map, instead of each Map having a unique name.
