What is the point of the deep reverence that the Japanese make when greeting?
Bowing has the same meaning for Japanese as shaking hands for Westerners.
Don’t you think, however, that so many bows are excessive?
It’s possible. However, if we consider that bowing our heads to another person is a sign of the absolute respect they instill in us, it is not too surprising that bows are repeated over and over again in greetings.
On the contrary, do we seem arrogant Spaniards to them?
It is true that this is the first impression we receive since when they shake hands they do not tilt their heads and look directly into the eyes with hardly a smile. However, it becomes natural for us as we get used to it.
