Watching Aikido practice, students seem to fall naturally. What kind of practice to you do for ukemi?
Kisshomaru Ueshiba: Unlike Judo, where you grapple with your opponent, in Aikido you almost always maintain some distance. Consequently, a freer type of ukemi is possible. Instead of falling with a thud as in Judo, we take circular falls, a very natural form of ukemi. So we practice those four elements quite diligently.
