Our tour guide, Xiao Hong, was very kind and provided detailed information about the attractions. He also sent us relevant information via Line, such as meeting times and locations, and Google Map links for the attractions, which made us feel very reassured. A small suggestion for the itinerary: the free time in Otaru was too short. It took almost twenty minutes to walk back from the main building of the Music Box Museum to the meeting point, making the return trip quite rushed. Two hours would have been more comfortable.
