In Shirakawa Village described the World Heritage site in 1995, the rethatching has been performed by reciprocal help called ‘Yui' traditionally. Originally it functioned in the various collaboration of the village. From the latter half of 1950s. ‘Yui' as rethatching began to decline, and from the former half of 1980s. the new position of ‘Yui' that is the object to preserve appeared in Shirakawa Village studies. Through that, the diagram called ‘Yui' = ‘rethatching' was born. And it changed into a viewpoint that ‘Yui' itself was important by described the World Heritage site in 1995. In addition, by newspaper articles and the media, ‘Yui' was taken up as a symbol of Shirakawa-go, the World Heritage site after describability. ‘Yui' meant not only rethatching, but also reciprocal help in the various collaboration of the village. A thing brought up by the cooperation of people and succeeded to at the present is a landscape of ‘living heritage' Shirakawa Village. We do not have to mind the present meaning of ‘Yui', and it is necessary to pay more attention to preservation all the things which formed the World Heritage site, Shirakawa-go.
