Please correct my essay:) How about in your country? Please give any tips!

First of all, Japan has faced is facing an Aging aging society. Poplation The population of Japanese workers has been decreasing decreased for last few years. Companies in Japan have bothered worried/been concerned about the lack of workers.

Secondly, the issue which I mentioned in the first reason the current worker shortage is more severe in aging senior/elder care field. It is one of the most unpopular (alternatively "least popular) jobs in Japan. I work for at an institution for aged people. Whereas Although we are always looking for someone to work together, it is difficult to find workers. Moreover, they quit from us very easily (more naturally, "there is a high turnover of workers").

Therefore, we need workers who compensate for the shortage.

It is for these reasons that the number of foreigh foreign workers in Japan will increase in the future.

Good job Etsuko.  Most of the corrections are simply to make things more natural sounding.
