Hitachinaka City is located along the Pacific coast of the Kantō region. The Ōarai coastline is famous for the Ōarai Aquarium and as a pilgrimage site for the anime *Girls und Panzer*. The landscape at the mouth of the Naka River is picturesque, and the Isogo coast is ideal for surfing. Hitachi Seaside Park features stunning seas of baby blue eyes (April) and kochia (October). Local specialties include Hitachi beef, anglerfish hotpot, oysters, seafood bowls, and watermelon—all sweet and juicy.
