Onigashima appears to be a Winter Island, with snow constantly falling. The landscape is dotted with bonsai-like trees.
The most notable landmark of Onigashima is a large rock formation resembling a skull with horns. This mountain appears to have multple buildings on and around it, and is easily visible from a great distance.
Kaido resides in a giant mansion somewhere on the island. Although it has yet to be shown in full, the mansion appears to occupy a considerable portion of the island, being large enough to house the abnormally large top ranking members of the Beasts Pirates. Inside the mansion is a cell which was once occupied by Eustass Kid.
X Drake and some other Beasts Pirates were outside Kaido's lair on Onigashima when they received news of Joker's defeat, which they tried shouting out to Kaido, unaware that he had gone to the Ballon Terminal.
Sometime later, Kaido returned to his lair and received a call from Scratchmen Apoo, telling him they lost contact with Jack. Realizing his plans to take back Doflamingo had failed, Kaido drank a lot and suffered from intense mood swings, including a rage that caused him to hit some of his subordinates through the roof of his lair.
Wano Country ArcEdit
- The island shares its name with an island in the Japanese folktale of Momotarō, where the titular hero and his animal retainers went to defeat the residing demons that were troubling people, similar to how the Ninja-Pirate-Mink-Samurai Alliance plans to take down Kaido, who was oppressing the people of Wano Country.
