NAGOYA, Japan -- Toyota Motor takes pride in monitoring its factory floors to maximize best practices. Now Japan's leading automaker is coming to terms with compliance failures that suggest this principle was not embraced at subsidiary Daihatsu Motor. " Genchi genbutsu is the most important concept for us, but we realize once again that we were lacking in this area," Toyota Executive Vice President Hiroki Nakajima told reporters Wednesday after 174 more examples of misconduct, including on safety tests, came to light at Daihatsu.
