"Introduction"...He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed." , this is the famous words of Albert Einstein which is German theoretical physicist. Everyone has such feeling clearly. The feeling is expressed by the words such as "move, touch, impress, inspire and electrify". Moreover, these words are comprehensively shown with the Japanese language "Kando". Generally, Kando means that the heart is moved greatly. However, Kando is passive feelings, and is not defined clearly. In other words, it is thought that Kando is variously influenced by the spatial and organic characteristic. PurposeThe purpose of this study is to clarify the psychological structure of Kando that is the feeling of organism obtained through the spatial experience. MethodThis study conducts the psychological experiment based on Semantic Differential Method to clarify the psychological structure of Kando. The procedure of experiment is as follows. 1) In order to develop the rating scale on Kando, the words with near meaning to express Kando are extracted by several thesauruses. 2) The spaces used for the experiment are the spatial pictures which are mainly concerned with Cultural and Mixed Properties except Natural Properties among World Heritages. And, the spatial pictures have the stronger degree that the heart is moved on the interview to subjects. 3) Those spatial pictures are projected on the large-sized screen in the dark room. Other subjects watch the spatial pictures, and describe the rating questionnaire items for Semantic Differential Method. 4) The result is analyzed based on Factor analysis. Results and Conclusions(1) Psychological structure of KandoAs a result of Factor analysis, several factors such as charmed and healed factors were extracted as the psychological structure of Kando. Moreover, each of factors has the degree that influences Kando. In other words, Kando is classified into several types through influence of the spatial and organic characteristic.(2) Transaction between Kando and spatial characteristicKando is influenced by difference in the spatial characteristic such as the composition and the time. In other words, each Kando appears when the conditions gather, like the daytime or night, the position and the angle at the time the space is watched.(3) Transaction between Kando and organic characteristicKando is influenced by the degree of knowledge about the spatial meaning which organism has. It is thought that the degree of knowledge is influenced by the spatial meanings such as the historic context and the personal experience and the knowledge given as information. "
