In our present time, most people would say “hi” or “hello” as a form of greeting. For some they greet each other by shaking hands or by just waving their hand while younger generation greet each other with a high five or give me five as a form of greeting and approval or mutual understanding. Others still, would greet each one another especially amongst the people in the socialite world, politics and showbiz by kissing one another. We call this “beso-beso” in the Philippines.
In some parts of the world, some cultural groups don't do the same as we do. Instead they have a unique way of greeting one another. Let's find out how they greet each other.

The Japanese Traditional Greeting
Bowing

And in Japan, bowing is probably the feature of Japanese etiquette that is best-known all over the world. Bowing is considered extremely important in Japan. Basic bows are performed with the back straight and the hands at the sides (boys and men) or clasped in the lap (girls and women), and with the eyes down. Generally, the longer and deeper the bow, the stronger the emotion and the respect expressed.
