"Treasure Island" is the name given by Senku to the island where Byakuya Ishigami and his fellow astronauts who survived the Petrification lived once returning to Earth. It is the main location of the Treasure Island Arc.
The Petrification Kingdom is the only known location on the island.
Having survived the Petrification while aboard the International Space Station, Byakuya and his fellow astronauts continued to survive on the island, and eventually began to repopulate. Recognizing that Senku would need precious metals such as platinum were he to be revived, he dedicated his life to stockpile the metal, hiding it away within a concrete slab at the center of the island. As part of the 100 Stories, he included a story indicating the location of the platinum, such that it could eventually be found.
Since that time, some chose to leave the island, eventually populating mainland Japan. Others chose to stay, and have since formed the Petrification Kingdom which now populates the island.
- The name of the islands may be a reference to the real-life story of Treasure Island.
- It is possible that this island is Takarajima,one of the Tokara Islands belonging to Kagoshima Prefecture
