Inside of Izumo shrine. Izumo in Japanese is 出雲. 出 for "out", 雲 for "cloud", they says the weather of this place change very suddenly. Unfortunately, when we got there I hadn't see any change, but sunny day. Cloud 雲 is expressed "Ryujin", 龍神(dragon's god=worship for a nature's god) sometimes from the long time ago.
