I feel that is weird.
The people stand side by side a line.
One of them says "Makotoni moushiwake arimasendeshita.誠に申し訳ありませんでした。"(I'm really sorry to everybody.)
So the people bow at the same time.
I have heard that they practice the performance ahead of time. Even some companies that advice how to apologize exist.
No one thinks it is meaningful. Who thinks it's going to solve the problem ?
It's just like typical Japanese. Old people called it "Misogi"みそぎ,it means ritual ablutions.
There is no solution planed. However, the fact remains that the sense of Japanese culture requires it.
Actually, I think the most important thing is substance rather than form.
We should take it seriously.
