The Japan Sanitary Equipment Industry Association, a consortium of companies producing plumbing products including Toto, Panasonic, and Toshiba, has agreed to unify the iconography used on the often baffling control panels for Japanese toilets. The decision was made in response to foreign tourists who say they’re often unable to understand the controls, which operate features often not found on Western toilets such as bidets and warm air drying. 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.
