In 'The 10th International Art Exhibition of Japan' (Tokyo Biennale), Yusuke Nakahara as general commissioner set a charactaristic and critical theme, 'Between Man and Matter' and convoked the 40 artists in the world, those who have embodied the newest trends. Those artists came to Japan and made works at Tokyo Metropolitan Art Gallery, therefore this exhibition is regarded as one of the international exhibitions, that were held worldwide 1969-1970 and showed avand-garde.

We have also supplemental records about the exhibition and relatively abundant informations about the individual works, on the other hand it seems that the study about the details of the exhibition itself still absent. Thus as the first step of re-investigation we try to reveal where the works were located actually in Tokyo Metropolitan Art Gallery, through researches on the materials.
