We are planning a 13-day trip to Japan focused on Hokkaido and we have some doubts about the itinerary to choose. We are fairly certain that we will visit Sapporo and Otaru, Furano & Biei, the islands of Rebun/Rishiri, and Noboribetsu and Lake Toya. However, we are very undecided about whether we should choose Hakodate or Shiretoko (and that region of the island) for the remaining days. What would you recommend? Is there any place we mentioned at the beginning that you feel is not really worth it and that you would replace with other locations, or would you suggest a different itinerary based on experience? thank you
