Tetsuya Toshima has been also active in the fields of TV programs and Graphic, interior, fashion to visual-communicate messages of concepts. He says, "I think I don't choose production measures to express consciousness of time. By means of this I believe I can generate works which have universality being similar to that of time. He keeps making the artwork with "time" as his main theme.
I am always competing against time. Time governs both life and death. The basis of time, past, present, and future, act as proof of one's existence. Therefore I sometimes fall into the illusion that I am being swept away in the flow of time. Time has a universality to it as it ticks by and bestows to my works a myriad of indefensible feelings and stories. I strive to create that universality in my works. Time is always fluid. I find the entangled fragments of stories in that fluidity and turn them into my works.
