As one of the earliest portal trading cities in Japan, Hakodate is full of Western flavor. This part of the buildings are concentrated in Yuanli area under Hakodate Mountain. It took only 30 minutes to walk from Chaoshi to Yuanding. Along the way, I was not impressed by the so-called Western architecture such as cathedrals, consulates and so on. Instead, they go from house to house in small foreign houses, each with a smart and delicate style and clean courtyard. The streets of Yuantang area are all leading to the seaside, which is called "Sakawa. Bakasaka is one of the most famous streets in Japan, and has been selected as one of the 100 most sentimental streets in Japan. You can see the sea at a glance. That kind of port city unique romantic tenderness pours on the face.
