Aomori Prefecture is the northernmost prefecture on Japan's main island of Honshu and is located at about the same latitude as New York, Beijing, Rome and Madrid. It is surrounded on three sides by the sea, facing Hokkaido to the north across the Tsugaru Strait and bordering on Iwate and Akita Prefectures to the south. The Ou Mountains cut across the central region of Aomori creating different climatic conditions on the Pacific Ocean and Sea of Japan sides of the prefecture.
Aomori City, which is the venue for the G8 Energy Ministers Meeting, is a city with about 310,000 inhabitants located at almost the geographical center of the prefecture. The city benefits from a superb natural environment, facing Mutsu Bay to the north and with a view of the Hakkoda Mountains to the south.
