The geography in the Ultra Dimension Planeptune is similar to that of the Hyper Dimension Planeptune in Hyper Dimension Neptunia mk2. It's still situated in the western region of Gamindustri's mainland and is filled with green grass, a few lakes, some forested areas, and even a resort near the ocean. It still upholds the futuristic and advanced appearance like its Hyper Dimension counterpart and also has a few towns situated in its vicinity.
