Terraportation (テラポーテシン Terapouteshion) is the method of transport used to move from one landmass to another in Hyperdimension Neptunia. The in-game explanation is that when two landmasses connect, a bridge is dropped to allow someone to cross over, but in order to use it, a person must acquire permission from the Basilicom. To Terraport, the player must "wait" for the initial landmass to approach the landmass of destination. Some landmasses appear to have different distances (approaching, very close, close, far, very far) from the initial landmass, but the player doesn't have to wait for a certain time before the other landmass approaches the initial. After the two landmasses approach, the player must then enter a dungeon and reach the exit to enter the other landmass.

In Hyperdimension Neptunia mk2, Terraportation appears but not in the way of how it is in Hyperdimension Neptunia. Terraportation is only mentioned in one event where Nepgear and her party must ride on a Terraportation ship from Lastation to travel to Leanbox.
