空島の商人 (Sorashima no Shonin) (Merchants of Sky Islands) is a tile placement game from Japan.

The Sky Islands float on the sea-filled planet Aquarius. The trade between the Sky Islands flourished by operating vehicles that used flying stones that generated anti-gravitational energy. This game is a story of the great trading era on the Sky Islands.

When tiles are placed, resources can be obtained through trade with neighbouring islands. Using the resources you gain, you can build trading posts, harbours, and towers to strengthen your power. Players compete for the majority of empty islands, and the player who earns the most victory points wins.
