Japan's leading bidet toilet manufacturers (including Toto, Panasonic, and Toshiba) have come together through their industry association, the Japan Sanitary Equipment Industry Association, to agree upon a common set of UI conventions for the meanings of the icons on the buttons on the bidets' control panels, thus ending an era in which you might think you were getting "wash and dry" but actually ended up with "layer-cut and dye-job."
The toilet manufacturers plan to implement the eight new pictogram on models released from this year onward, with a view to the system becoming an international standard. The icons in the image above mean (from left to right) raise the lid, raise the seat, large flush, small flush, rear spray, bidet, dry, and stop.
