Hakodate is Hokkaido's third largest city, located at the island's southern tip. Hakodate is best known for the spectacular views to be enjoyed from Mount Hakodate and its delicious, fresh seafood. As one of the first Japanese harbor cities to be opened to international trade after the country's era of isolation, Hakodate has experienced notable influence from overseas, and the foreign population's former residential district and a Western style fort are among its main tourist attractions. Onuma Park, a quasi-national park with beautiful, island dotted lakes, is located only half an hour north of Hakodate and makes a nice side trip or a stop along the journey between Hakodate and Sapporo.
