Hinakuu was a planet found in the Hinakuu system. This system was situated inside the Calamari sector, which itself was a constituent of the Slice region within the Outer Rim Territories. The Tidal Circuit hyperlane provided a connection to both the Krinemonen and Sanctuary systems. Individuals from the Mon Calamari species, originating from the Calamari system, colonized Hinakuu. These Mon Calamari expanded from their original planet and homeworld, known as Dac, utilizing Mon Calamari starliners during the period between 4400 BBY and 4200 BBY.
The Essential Atlas, a reference book from 2009 that was written together by Daniel Wallace and Jason Fry, first presented Hinakuu. It located the planet within grid U-6.
