On one occasion, the hospital asked him if he would try to repair a reed organ. He agreed and was able to repair it successfully, marking the first step toward the birth of the Yamaha brand. Recognizing its business potential, while repairing the organ, Torakusu created a blueprint for the inside of the organ, later creating his own prototype organ. To deliver it to the then Music Institute (today's Tokyo National University of Fine Arts and Music), Torakusu slung his creation over his shoulder on a carrying pole and crossed the mountains of Hakone. This historic trek was later immortalized as a bas-relief.
