The marvelous shoin structure of Jikō-in, a small temple located in the western part of Nara, deserves our admiration. I don't know of anything that can match the beauty of the spatial construction of this building. Some criticize the building for its crude structure and for a plan that seems to be nothing more than a reflection of the feudal way of life, but these beautiful spaces rise above all such criticism. To eliminate such forms would be to eliminate what remains of Japanese culture. Let's try to correctly evaluate the spaces of the magnificent Jikō-in. The idea that there is an intimate connection between the ancient Japanese heritage of a sense of space and the point at which Western architecture finally arrived was very strong after the War. This gave the Japanese people confidence and helped them quickly recover from the defeat in the war; However, it is clear that the beautiful Japanese spaces and the new spaces realized in modern architecture are not things of the same nature. Looking at the two, of course there is a connection, but that is only the feeling that the architectural spaces give, and it would be a mistake to believe that these two were homogeneous. The nature of these spaces is very different because the background of Western architectural space and the intricacies that intertwined to create Japanese spaces are very different. In his important work Space, Time, and Architecture, Sigfried Giedion uses a wonderful method to develop a discussion of architecture. He says that there is a direct connection between the architecture of a period and the concept of space that that period achieves. I don't think there is another suitable explanatory work on the solid background of the modern western arc...... middle of paper ...... part of the life of the nobility of the middle ages, and later passed on to ordinary people, can be considered a form of coercion. The aesthetic sense of the nobles can undoubtedly be extracted from this ideal of Japanese spatial expression. However, the reason why this was able to develop into such a splendid ideal is not so much a reflection of the indecisive and evasive Japanese view of the world, uncertain, as the fact that, thanks to the strength of the aesthetic sense of the creators, the true uncertainty of the worldview has been elevated to the status of an ideal. If we follow Giedion's explanation and consider modern architectural space as space-time, Japanese architectural space is of a completely different dimension. The goals and concepts of modern architecture, focused on high transparency and flexible space, and traditional Japanese space are very different..
