Which is better for the future, business Japanese, tourism Japanese and Korean?

It's simple. Of course, you studied tourism Japanese at the tourism school. Sometimes employers are like this. If you value employment, you'd better choose this one. As for business and tourism, there is not much difference, and the whole business Japanese is not enough.

Korean is a hobby, because Korean companies are stingy, just like Taiwan Province companies. Do you know Foxconn? Korean and Japanese have similar grammatical structures, and Korean is also easy to learn after learning Japanese.

Give me some advice. I have personal experience.
