The Japanese toilet industry has come together and agreed to standardise the icons used on their complex and confusing high-tech toilets.
Tourists have often struggled to understand the control symbols, leaving them pants-down and bewildered in front of a frightening array of features - which include "rear spray", "large flush", and "raise lid".
Faced with the incomprehensible range of options, more than one foreigner has made a terrible mistake and pushed the wrong button - sometimes with disastrous results.
Ahead of the 2020 Olympic Games in Tokyo, Japan is focused on making their country more tourist friendly - and fortunately the Japan Sanitary Equipment Industry Association is ready to do its bit.
Their new combined standard will implement a system of eight new pictograms, with plans to make them the international default.
As shown in the picture, the options will now read - from left to right - raise the lid, raise the seat, large flush, small flush, rear spray, bidet, dry, and stop.
