Otamatone creator Maywa Denki is an art unit formed in 1993 by two brothers, Masamichi and Nobumichi Tosa. Art unit is named after a company their father Maywa Denki Ltd in Ako city.
Company produced accessories of screens for Toshiba and Matsushita Elektric. After while company grew into a medium-sized at peak. Factory doors were closed in 1979 due to the oil-shock. After 14 years was the name resurrected by Tosa’s sons Nobumichi and Masamichi. Since then they attempt to get their activities beyond the classical art, describing their works as “products,” and their live performances as “product demonstrations”. A typical Maywa Denki´s element is wearing blue work uniforms of Japanese electric stores.
