Saudi culture vs Japanese culture

I involved in an interesting project which is a 50-50 joint venture project between the Saudi and the Japanese (Aramco and Sumitomo Chemical) who are respectively from 'extreme' different cultures.

Among those, the Japanese stay back in the office until late evening; but the Saudi leave the office punctually.

The Saudi must bring the whole family when they are on a long period overseas assignment; whereas for the Japanese, they go overseas alone with their family remain in Japan.

The Japanese bow to each other when they meet. The higher degree one bows, more respect is transmitted. Whereas, the Saudi cium each other's cheek when they meet. The more cheek ciuming is, the closer brotherhood is shown.

Haha, one more: Generally, the Japanese like to drink, but officially the Saudi can't drink at all because of religious reason.
