Aomori City (�X) in Aomori Prefecture is the northernmost prefectural capital city on Honshu, Japan's main island. This port town used to be the main departure point to Hokkaido via ferry; and, although it remains the main port for car ferries, the opening of the Seikan Undersea Railway Tunnel and the advent of cheap flights have reduced ridership and many travelers now bypass the city altogether. Today Aomori is best known for its spectacular Nebuta Matsuri summer festival.
