In western and Japanese, The word "yes" is a different mean.The word yes mayn't alway mean “yes” in the Western sense but Japanese people may say yes to confirm they have heard or understood something but not necessarily to indicate that they agree with it. You’ll seldom get a direct no. Some of the ways that Japanese people say no indirectly include “It will be difficult,” “I will ask my supervisor,” “I’m not sure,” “We will think about it,” and “I see.”
