Kohei Odaka created it: it's called "Black Cube." The restroom is a narrow space made of charcoal. The only source of light is a luminescent toilet seat. Kohei explained why he used charcoal for the walls: "The special qualities of the charcoal, which dehumidifies, deodorizes, and emits negative ions, soothe the body, and the reduction of visual information to a bare minimum sharpens the senses and creates a pleasurable sense of tension." Over a thousand entries were received for the competition sponsored by Toto Ltd., the stylish Japanese bathroom fixture company.
