China's psychological counseling certificate is not recognized in Japan.
If you want to work in Japan with the knowledge of psychological counseling, you must obtain the qualification certificates of psychological counselors issued by various psychological counseling associations in Japan. For example, the qualification of "Japanese industrial psychological counselor" or "all-Japan professional psychological counselor".
Level 2 of these qualifications is easy to get, as long as you attend two-day intensive lectures, but those with level 1 must attend lectures for half a year.
The profession of psychological counselor will be paid more and more attention. Especially counselors who know Chinese. Because there are more and more mental illnesses among China people working in Japan, major companies are looking for countermeasures.
