I think that Japanese companies should hire more foreign workers. I have two reasons to support my opinion.
First, the aging Japanese population is increasing. In fact, the number of Japanese workers has also decreased, therefore they have to work harder than in the past. We need more foreign workers to get better work styles.
Second,the world is becoming more globalized. Recently, a lot of foreign people are coming to Japan for the trip. If there are foreign workers in Japan, foreign visitors will be able to communicate with foreign more smoothly. That will make more foreign people visit Japan because they don't have the problem of language.
Considering these reasons mentioned (stated) above, I think it is important for Japan to hire more foreign workers.
2つ目の理由は添削者が理由を理解するのは少し難しいのでより、文章をわかりやすくしてみました。
最後はfor these reasons stated aboveと書いてもいいと思います。
参考になれば、嬉しいです!
