In many Japanese toilets, you’ll find an ingenious design where the sink is integrated into the top of the tank. This system allows you to wash your hands, and the used water is then reused for the next toilet flush.
This practice is not only efficient but also significantly contributes to water conservation in Japan. Every year, millions of litres of water are saved thanks to this simple yet effective innovation, highlighting Japan’s commitment to sustainability and smart technology.
