Lit. tortoise island. A small island made with several stones that express the head, feet, and tail of a tortoise. Found in both wet pond and dry pond *kareike 枯池 gardens, it is symbolic of longevity and often features in gardens where Mt. Penglai, *Hōraisan 蓬莱山, is represented. According to ancient legend, Mt. Penglai was borne on the back of a tortoise. The stones representing each part of the tortoise have names: the tail may be indicated with a tail stone *biseki 尾石 or osaki ishi 尾崎石, the legs with the leg stones, kikyakuseki 亀脚石, the head with the head stone, kitōseki 亀頭石, the feet with the foot stones, kisokuseki 亀足石, the front fins with the hand stones, kishuseki 亀手石 and, in a few cases, the carapace with the shell stones, kikkōseki 亀甲石. Usually a pine is planted on the kamejima to indicate the connection with immortality. The kamejima is invariably paired with the crane island *tsurujima 鶴島.
