he knows whom to show his respect,the most important thing in Japanese culture are manners and respect

a bow in japan is a sign of respect.

This editing cracks me up. Well for anyone that cares, Princess Diana also showed proper respect to the Emporer by doing two full deep curtsies. Although, she was never a Queen so an Emperor would have heirarchy over her.

"[The bow] is part of a greeting, with which one shows his or her willingness for the meeting." - Reiko Kasai, chief instructor at JAL Academy.

Just coming back from Japan. Glad our president respects their traditions. Shows an amazing understanding of foreign cultures in general. This is why is so respected and listened to abroad. Open your mind, travel a bit, you'll see what I am talking about.(Still has no clue what G.W was trying to do while looking for that hidden door in China! Remember those days?)

lol I love the music. So dramatic lol

He did the right thing.

I think this shows that he is a straight forward person. He carried his umbrella while stepping out of the aircraft at Shanghai airport.

He is simply showing respect to his imperial majesty

It was also kinda stupid in that he took his eyes off the person he was bowing to, and tried to shake his hand at the same time.

King of Morocco looked ready for a night on the tiles nvm meeting the emperor lol.

His Majesty is returned the bow.

The bow was originally meant to show opposing generals that they had no sword on their back while maintaining a forward facing angle.

they do, it's very common in business, it's a little bow/shake combo they do with foreigners only. Lean slightly into your handshake, hajimemashite

looks like he is going to kiss his shoes.lol

No...he is actually right. All the pictures of the Emperor shaking hands with other leaders were not in Japan. While in Japan you bow to the Emperor. It is called following customs. Sorry that Obama pays attention to the customs of the countries he visits.

ahh mad respect for the simian one , i think he should bow at burger king and eat the urinal cakes

"Get on your knees and tell me you love me"
