TOKYO -- Japanese toilet makers have for years been developing water-saving technology and bringing more comfort to the lavatory experience. They are now working to develop toilets that can contribute to people's health, power generation and even agriculture.
Yukihiro Fukuda, general manager of Japanese toilet maker Toto's research institute, called the Toto Universal Design Center, has a unique vision. "I would like to transform a home toilet into a health check room," he said. At the R&D center in Chigasaki City, Kanagawa Prefecture, he and his colleagues are working on the prototype of a heath-checking toilet that they aim to commercialize around 2020.
