Osaka-based showerhead maker Science Co. has developed a cutting-edge washing machine for humans aptly named “Mirai Ningen Sentakuki” (Human Washing Machine of the Future).

At the 1970 Osaka Kansai Expo, Japanese tech giant Sanyo Electric Co., now Panasonic Holdings Corp., launched the world’s first-ever human washing machine. Its futuristic egg shape and bubble technology captured people’s imagination and drew huge crowds to the manufacturer’s booth. Yasuaki Aoyama was one of the many people who got to see Sanyo’s washing machine in action. He was only a curious fourth-grader at the time, but the feeling of awe stuck with him all through adulthood, and today, as the chairman of Science Co., a company specializing in bathtubs and showerheads, he is preparing to launch his very own modern washing machine for humans.
