What is Wari?
Wari (わり) is a concept to which kinbakushi Chimuo Nureki attaches a very high value in his practice of kinbaku. Nureki believes that the authentic kinbakushi must have a sense of wari. He has often said: "So many women, so many ways of kinbaku". If the kinbakushi has a sense of wari, he/she can instinctively find the best ratio, length, balance or strength of kinbaku for the bottom to draw out the beauty of kinbaku. Chimuo Nureki has often stressed in his lectures that "this position of nawa (rope) is very important. If the nawa had been 1mm off, that would completely kill the beauty of kinbaku."
