Hakodate’s famous morning market is held daily from 5am to noon just a few steps from the main train station’s west entrance. More than 360 tightly-packed stalls offer for sale various types of fresh seafood such as crabs (kani), salmon eggs (ikura) and sea urchin (uni), and fresh produce such as melons. Also in the market area are several restaurants which offer fresh seafood breakfasts.
A five minute walk from the market will take you to the moored Seikan Strait ferryboat called the Mashu Maru Memorial Ship, which used to link Aomori in Honshu with Hokkaido. There is a restaurant and a coffee shop at the bow where you can spend a nice, relaxing time viewing the scenery around the port.
