You Hiroshi Fujita was born in an era where no plastic. But at present there is a lot of plastic. And when he has the ball he did not want his children to use plastic. I saw the toys in a room with a lot of it. And there are some pieces that had to be discarded. He is thought to be from plastic toys to benefit. Start by gathering toys available. And has started his own home. The idea is that the plastic carcass or fuel have created works inspired by the animals and dinosaurs. Toys to make them more attractive and do not become waste.
