When I got at Sapporo station, I bought a ticket for limited express train, named Okhotsk, to Abashiri (網走), which would departure at 7:21, taking me JPY9130. So I looked around Sapporo station. Hokkaido University is very near Sapporo station.
I transferred to Shiretoko-Shari train at Abashiri station. About at 15:00, I arrived at Shiretoko-Shari and got on the bus to Iwaobetsu, where I would stay at Iwaobetsu Youth Hostel for a night.
After I checked in, I talked with my dorm-mate, who had been at Iwaobetsu YH for 3 days. He told me about some must-see in Shiretoko, but I did not have enough time and money. So I decided to see Furepe waterfall in the afternoon and Shiretoko-goko (知床五湖) in the next morning. Thanks to a staff who picked me up after I saw furepe waterfall.
