I signal an interesting post on arama.

Grossberg said a common problem at Japanese companies is “group think” that makes it hard for an individual to raise a troublesome issue.
“It either falls flat and people ignore it, or it creates a problem for the individual who brings it up,” he said.

I think the last certainly is a cultural overstatement that favours non-Japanese companies. First sentence of that quote I’ll buy as something generally containing truth. I sometimes wonder what that is like working at a Japanese company with 99% Japanese… lol.
