Printed characters are Simplified Chinese, not Japanese.
In fact, Japanese language is not so international one. Coverage area is Japan only, any other areas and territories do not take it as their first common language. Even if you can use Japanese fluently though, availability is extremely less than Chinese language. A part of Japanese people settle down in another countries, but they do not have strong connections each other across the globe. On the other hand, Chinese people have very strong international connections each other with a long long history. Not only that, Chinese people have stronger connections with each countries’ government or publish people by good friendships and relationships in most of cases.
However, in case of most of Japanese, they can have just company2company relationships, so they are not good at build up the regular good relationships with each countries’ government and public people. (Please check the case which Govt of Japan had made Govt of Congo soooo angry. They misunderstood how to make relationships with another countries’ government.)
In addition, Chinese people have good business sense among East Asian countries. So, if you can get a trustable Chinese business partner, it would be very helpful for you.
If you want to work with Japanese people, you would better to ask them to do middle level management, quality control and facilitate duties, because they are suitable duties for Japanese people.
A plenty number of Middle East rich Arabic people have strong interest to study in Japan though, most of them have given up to do it, because the cost-effectiveness of Japanese language and study in Japan are incredible too bad.
For example, even if you will graduate from the top university of Japan though, your salary will become much much much lower than the graduations from IIT(Indian Institute of Technology) and IIM(Indian Institute of Management) of India. If you want to earn more in your life, you would better to graduate from other countries’ good universities.
Anyway, many foreign countries have been removing Japanese language from their official curriculum for these years, so I’m not sure whether learning Japanese language is the best choice for you. If you want to do worthy international business, I strongly recommend you to learn Chinese language. If you want to know full of Japan issues, I surely recommend you to learn Japanese language.
