Zenzaburo Kojima is an incomparable artist who boldly merged duality of cubic expression obtained in his studying days in Europe and Japanese flatness-expression in the same canvas. In particularly at landscape painting, he had achieved merger of flatness and cubic depth which Great Picasso had never achieved. And he also had succeeded in configurating compatibility of emotion and color. He applied these dynamics freely into still-life painting and flower― vase painting in his final years. The paintings were strictly configurated one by one, and they have been giving viewers still pleasure and satisfaction.
