Kibo Island is one of 34 islands surrounding Whole Cake Island as part of Big Mom's territory, Totto Land. It is run by Charlotte Marnier, the Minister of Yeast.
Kubo Town (クーボタウン Kūbo Taun?) is a city situated on the island.
Less than 62 years ago, Kibo Island became part of the Big Mom Pirates' territory Totto Land, and Charlotte Marnier was appointed the minister in charge of this island.
- The Japanese name of the island, Kībo-tō (キーボ 島) may be a pun to キーボード, the Japanese pronunciation of "keyboard", fitting with the series of music-themed names seen in Whole Cake Island.
