In the context of your other post, I think that it's not a peculiarly Japanese response. I would think of it in that context as an expression of the feeling "there's nothing I can do about it".
However, I also think that in Japanese culture, it's more common than in English-speaking culture to express feelings of "there's nothing I/we/you/anyone can do about it".
In English-speaking culture (please let me know if you agree), a person who often expresses such feelings of some kind of "helplessness" is likely to be looked down upon as not being motivated, self-empowered, etc. It seems to me, in Japanese culture this is not the case and expressions like this are more likely to elicit understanding, fellow-feeling and respect for a persons humility.
