What jobs can people who understand both IT and Japanese do?

Well, it depends on how well this person understands "IT" and "Japanese".

There are also many "fields" in "IT", as well as levels of level.

Based on the "IT" technical level, experience, management and leadership capabilities, the work that can be done is also different.

1. If you have a little programming experience and know a little Japanese, you can work as a programmer in an IT company run by Chinese people in Japan.

Work under the guidance of Chinese IT personnel who are good at Japanese.

2. IT workers who speak Japanese a little better and can communicate with Japanese technical personnel, Chinese people who have good IT skills and have IT work experience can go to Japanese IT companies in Japan to do technical work.

3. People who are fluent in Japanese and have experience working in IT companies and management can be employed as "bridge engineers". Or an "IT company doing business with Japan" that operates and manages.
