I have depicted buildings representing each period of Japanese history, from ancient times to the present day. I have visited these places myself, and I am very proud of the cultural heritage that has been handed down over time. On the other hand, I also feel that the human desire for power and authority is endless and that history repeats itself. I superimposed the Tower of Babel on the composition of buildings piled up on top of each other, and the repeated history is expressed by the same buildings (the Gate of Nikko Toshogu Shrine and the Great Buddha of Todaiji Temple) being built on the island in the foreground. A gentle warning is also included.
