The island used to have a factory for poisonous gas, so it was erased from the map.
Now it is a part of a registered national park. 600 wild rabbits living on the island draw lots of tourists, who come to spend a relaxing time with the animals. The whole island is the ground of a national park resort with the name of Kyukamura, so visitors can enjoy cycling, camping and taking a hot spring bath, surrounded by beautiful nature.
