I've got the source of the research, which I mentioned in the previous etnry. The research was reported in Japanese but I created its summary here.

Survey: Attitude to jobs and workplace of FY2003 Regular new-hired employees

The survey was done by those who attened the job training course Sanno Institute of Management offered in March and April in 2003. 462 out of 600 attendees answered the survey.

Summary: 2003 new hired seem to have decreased aspiration of challenging, due to the long recession of Japanese economy with little hope. These new hired prefer staying at large firms rather than starting ventures so that they want to acquire skills valid at large firms. Majority of these new-hired want to end up becoming directors at large firms, showing they long for stabilization of life. They look very conservative.
