Vipassana yoga originated in India and Zazen, has its roots in Japan and China. These cultures have been so long with each other that it is quite possible that the practice stems from the same roots.
The Vipassana yoga is a form of yoga in which one's movements slow down as much as possible. It is often combined with a period in which one remains in silence and not talk. Slow movements require a lot of concentration, and that helps to be more aware in the present now and here. Loving presence and attention are key concepts.
