Takenori Takehata (Tatehata kakoko, April 22, 1919 - February 16, 2006 ) is a Japanese sculptor . It was a leading figure who promoted abstract sculpture production in Japan after the Second World War.
He tried to eliminate emotional production attitude and inertia and to make sculptures with clear and logical thought. On the other hand, he tried to push the structure of the sculpture to a pure and rigorous state, to create an inorganic form that wasted away, from there to see the possibility of shaping.
Meanwhile, beyond such pure shaping, I tried to establish organic things such as my own images of human beings, lives, fantasies and the like in sculpture. He tried to integrate organic things like sculptures such as inorganic formations that promoted theory and theory and life feelings coming from their own feelings, and as a result, they created works that are pure, neat, yet humorous It was.
Incorporating not only bronze but also all kinds of materials such as iron, aluminum, plastic, acrylic, cement, etc. In the 1980s worked on plywood.

Before the war, he received high revaluation for his precise and realistic modeling of human figure. But after the war, he turned around and aspired for new expression of sculpture.
His study experience in Paris from 1953 to 1955 oriented him decisively toward avant-garde or innovative art. First he sought for organic form based on human body, which was influenced by an English sculptor Henry Moore, then moved to creating humorous forms which was adopted from familiar motifs.
Moreover he kept developing his forms with plywood and found ones that give us sense of movement in geometrical forms.
