Maritime transport in Aomori Prefecture operates primarily from the ports of Aomori, Mutsuogawara, and Hachinohe, though smaller ports are found throughout the prefecture. The ports at Aomori and Hachinohe both serve cruise ships and ferry lines. Additionally, a ferry line operates between Ōma and Hakodate. Prior to the opening of the Seikan Tunnel, rail ferries operated by the Japanese National Railways linked Aomori Station and Hakodate Station as the primary connection between Hokkaido and the rest of Japan. A museum dedicated to the historic rail ferries operates near Aomori Station in a former rail ferryboat, the "Hakkoda Maru".
