When Japanese executives are forced out of their companies, they usually go quietly, a final sign of corporate loyalty at the end of a long career of service. But now the rules are changing. Kuniaki Nozoe has stunned Japan by challenging his ouster as president of Fujitsu, a technology company once considered dynamic. In recent years, Fujitsu has been plagued by declining margins and trouble expanding outside of Japan. "Fujitsu is typical of the fusty, complacent, corporate culture and this is one of the real problems facing Japan Inc. these days," said Jeff Kingston, a professor at Temple University, Japan Campus.
