Syowa Station is located on the East Ongle Island in the Eastern Antarctica, or south of the western Indian Ocean. The island is about 4 km distant from the Antarctic Continent, and because of this distance, the climate is less severe in comparison to other Antarctic stations. The ground is covered with snow through 10 months and it supports some very hardy vegetation. Mosses, lichens and liverwort grow when the ice retreats. Annual mean temperature is about -10 °C. Annual mean wind speed is 6.4 m/s
