Could you check and correct my English writing?

In recent years, a lot of foreign people came to Japan and some problems are happened.
First, it is hard to communicate with foreign people because a number of Japanese can speak only Japanese. People who come to Japan are not only from English speaking countries, but from Brazil, China and so on. It would be better for Japanese to learn how to say hello in other languages.
Second, different countries have different common senses. Some foreign people feel resistance against Japanese common sense.
In conclusion, there are some issues when foreign people come to Japan, but you should consider how to live together.
