One of typical symbols of the city of Yokohama, the second largest city in Japan, would be a seagull or something about sea.
The history of Yokohama is surprisingly short, 150 years and it could be said a sort of a diplomatic history. Yokohama was just a small village for fishers. The small fishery harbor appeared in front of Japanese diplomacy 150 years ago.
Hikawa-maru was a ocean liner between Yokohama, Vancouver and Seattle and then it was used as a hospital ship in the World War II. Today you can see her at Yamashita-koen park as a symbol of Yokohama.
