Start your day in Hakodate exploring the morning market as well as Japan's first western style fortress, Fort Goryokaku. Head for Mount Hakodate towards sunset and enjoy the celebrated night view over the city.
Travel by train from Hakodate to Lake Toya. Take the Usuzan Ropeway to get panoramic views of Lake Toya and Showa Shinzan or follow the walking trails around the mountain's newer craters to see ruins caused by the eruption in 2000. Overnight in Toyako Onsen.
Not far from Lake Toya is Noboribetsu, Hokkaido's most celebrated hot spring resort. Enjoy the high quality waters and explore the water's source, the hell valley. Overnight at one of the town's onsen ryokan.
Drop by Biei, a town surrounded by picturesque landscape and flower fields on your way to Asahidake Onsen. Stay in Asahidake Onsen for the next two nights.
Travel from Sounkyo to Shiretoko National Park, another of Japan's most beautiful and unspoiled national parks. Enjoy exploring the national park and spend two nights on the peninsula.
Stop by the Kushiro Marshland on the way to Kushiro. The park supports the only known population of endangered Japanese cranes. Kushiro Airport provides flights to Sapporo, Tokyo and a few other destinations.
The above itinerary is somewhat fast-paced. Tourists preferring a slow pace of travel should consider spending more time at some of the destinations along the way.
