This paper aims to show an aspect of Kunio MAEKAWA's theory of poiesis by focusing upon his writings about "technique" and "spirit".The main subject consists of the following chapters according to the issues raised in the second chapter. The third chapter describes the relationship between "technique" and "human spirit" in his writings. The fourth chapter considers the "spontaneity" deeply concerned with "techne(technology/art)" and "spirit (mind/heart)" which have been looked at in the third chapter. Thus, the structure of the concepts in connection with Maekawa's poiesis have been discussed. In the modern ages which passed through specialization and division of "technology" and "art", Maekawa's poiesis offers his approach to reunite them based on " human life".
