Where do we come from? What are we? Where are we going?
This is the title of a work which was painted by Paul Gauguin.
This question is the first proposition in my work.
In my debut work, I questioned human existence by representing its traces. In a work entitled “A Scene or Dedicated to Manet's Lunch on the Grass", I scaled out plates of food, cutlery, wine glasses, leftover fish bones and vegetables and laid them out on the grass.

For my next work, I turned my attention to the earth and the universe. Based on the words "the origin of life" and "the water planet earth", I expressed the human activity and the wave of water. The water wave is made of stone and floats on a metal bottle. The title of the work is A scene or "dedicated to Handel's The Water Music". Waving water representing the source of life and the bottle representing human existence and human society.I tried to express this proposition by showing a scene where a human message arrives across the sea from a world different from the one we live in.
Then my thoughts took a turn towards adding a physical perspective and I began to explore the theme of Time and Space.

Aristoteles and Platon considered time to be a moving likeness of eternity, because time is created by the movement of celestial bodies in a constant circular motion, and we can see the connection with eternity as permanence. The work entitled "pulse of earth," is my own expression of this idea.

This was from about 1984 onwards, but it changed as my interest in the formation of the universe and the theory of time deepened, leading to the work Locus of time from 1998.

The following is from the September 2010 issue of Nikkei Science: Is Time Real by c. Callender Newton once believed that there is only one absolute clock. The world shares this clock, and a minute is a minute for everyone. What happened first and what happened second were assumed to be the same.

But as physics developed, these assumptions were overturned at every turn. According to the theory of relativity, the future of things is often indeterminate, and the time elapsed varies with gravity. Time can change according to the observer, and there is no longer a single absolute clock.

However, quantum mechanics, another stalwart of modern physics, sees time in a very different way to relativity. Time in quantum mechanics is essentially, though controversially, a throwback to Newtonian time. The integration of relativity and quantum mechanics is a long-cherished dream of physics, but it is difficult to achieve if there is such a huge difference in the way time is understood. Various theories, such as the loop quantum gravity theory, have been explored to find a solution, but no definitive solution has yet been found.

The physics of the beginning of space-time from the Big Bang 13.8 billion years ago, and the development of theories from there, is very important. Based on these theories, I have tried to formulate my own sensory thoughts.This is the starting point of my work Locus of time. When we speak of time, the phase of the present is constantly passing away into the past, and the future is constantly changing into the present. In this phase of change, time is something that is passing, something that is flowing away. And we feel that our lives flow with the celestial bodies, changing with them.

In the meantime, I have also developed a different approach to thinking about time and space in a work called "relation", in which living wood and stone are interlocked. It is an expression of the relationship between life and time, over a long period of time, through the changes brought about by the forces of nature

The work "Floating Time" is a combination of natural and stick-shaped stones. It is a representation of time as it occurs to the individual human being.

In his theory of time, Aurelius Augustinus says It is in this gap or chasm, which is the chasm between being and non-being, between arising and ceasing, that the dynamism of time is concentrated, so to speak, in the creation and disappearance of the being. It is in this gap or chasm that the dynamism of time is concentrated.

And 'the concentration of the mind on the present casts the future into the past. It is also said.This is the source of the inspiration for this work Moreover, in 2018, this will involve the original proposition about the future of humanity: where do we come from and where do we go? The increasing harm caused to the planet by human activity has forced us to focus on the issue of environmental pollution. The work, entitled Origin, is a call to action for environmental conservation, in which the viewer is invited to participate. Specifically, we asked people from all over the world to collect water from oceans and rivers in the natural world, and to embed the capsules in the stones of the work. It is a system that allows the act of collecting water and the viewer of the work to publish information about the water environment on the web. At a time when the spread of microchip contamination is an accelerating danger to life on earth, we feel compelled to make this appeal loud and clear.

In this way I have continued to work, albeit from different angles, through thoughts of space-time starting from the Big Bang, the water planet Earth and human existence. I have named this body of work the Big Bang Symphony and will continue to work on it.
