"*Binbo-Yusuri" – It's to draw out your inner beat while you concentrate. It's closely connected between the "to think" as your brain works and the "to shake" as your body works. Patterned after *Binbo-Yusuri, YUREX™ is designed to control your rhythm, and act as a barometer of your concentration. YUREX™ is the first ever device which enhances your concentration and your creativity based on the BBU theoretical concept pioneered by Nobumichi Tosa, President of Maywa Denki.
