Most foreign and exotic culture in the entire world when compared to your own?

[Iloko]

In your own personal position and opinion on this matter..Which culture/group out of all the ones in the entire world today would you consider as having the most foreign and exotic cultural system when compared to your very own culture?

For example: Bushmen tribals of Africa; Yanomami tribals from SA; North Korea domain; maybe Russians; etc...

....And also if you'd like to share concerning the 'most similar' and comparable cultures to your own as well....

[Al-Meksiki]

Mongolians, Kazakhs, other nomadic or semi-nomadic people from the Eurasian Steppe. I've always been fascinated with them, both their ancient ancestors and their modern descendants

[Jacques de Imbelloni]

Japaneses, saudi arabians, pashtuns we latin americans found these societies puzzling.
