Foreign trainees have claimed to be mistreated in a Japanese firm while assembling cellphone parts. Six Chinese workers have reported to have been assigned to 16 hour workdays with unhealthy working conditions. These foreign trainees were promised job training, better life and good pay before arriving in Japan, but it turned out to be a completely different story. 
Critics say these foreign trainees have been exposed to unusual and life threatening working conditions with few legal protection. Government statistics show that a high percentage (experts consider it to be a high rate for young people who have passed strict physical tests to qualify for the job) of foreign trainees have died in the past 5 years mainly due to strokes or heart failures which relate to the wear out of excessive labour.
These Japanese firms are clearly violating simple business ethics that includes legal rights and safe working conditions. This is seriously considered unethical due to the fact that the article mentions that even the United Nations, human rights groups and several court cases could not stop this problem. Japan already faces the problem of labor shortage in farms and family-run factories. Nevertheless, it will damage Japan’s reputation.
