I'm living in Nakashibetsu. Nakashibetsu has an airport where you can come to from Tokyo or Sapporo. If you are planning to go to Shiretoko, you should stay here and rent a car. Then you can enjoy Shiretoko AND other places in east area of Hokkaido. I'm living alone. Because of my job, I might not be very flexible to your plan. However, if you're gonna come, I will do as much as I can(hosting, eating out or taking you to cool places...) I'm very interested in traveling and doing something cool!!! Let's explore HOKKAIDO together!!
