In most collectivist cultures, direct confrontation of another person is considered rude and undesirable. The word no is seldom used, because saying “no” is a confrontation; “you may be right” and “we will think about it” are examples of polite ways of turning down a request. In the same vein, the word yes should not necessarily be inferred as an approval, since it is used to maintain the line of communication: “yes, I heard you” is the meaning it has in Japan.
