This trip was extremely satisfying. The itinerary lived up to its name, and the tour guide was meticulous, attentive, and highly professional. I can only express my gratitude! Without this ecotour, it would have been very difficult for me and my family to complete this tour on our own.
During the brown bear breeding season, a professional guide is needed to enter the Shiretoko Five Lakes. The comprehensive explanations were very informative, and the scenery of the lakes and mountains was also very beautiful.
