The city of Yokohama developed when the Japanese-American Treaty of Friendship and Trade was signed in 1858. Even now, there are many places where you can get a feel for history: from the opening of the port to the present, Yokohama is an absolutely charming port city. The foreign settlement created during the opening of the port was to be subsequently expanded. Since the opening of the port of Yokohama, many foreigners have moved to the area, and about 100,000 foreigners now live and work here: it is said that there is a deep connection with foreign countries. One of the prime examples is the very famous Chinatown Yokohama.
