Not all cities have Chinatown. There is only one Chinatown in Yokohama.
Is there one in Osaka?
No, but there is a small shop opened by a Chinese who specializes in selling things from China.
Is it a shopping place or a community where Chinese people live in concentration?
A: I sell things on the first floor of Zhonghua Street in Yokohama, and then I live on the second floor. If the house is your own, you can decorate it at will.
Are there many China people there?
There are many people in China, especially in the city center. People in China like to be lively.
