One of Japan's leading industrial designers, Kosugi graduated in industrial arts from the Tokyo School of Fine Arts before working at the Industrial Arts Institute (IAI) in 1944. After the Second World War he worked as an independent designer, his designs including a series of three‐wheeled trucks for the Toyo Kogyo Company (now Mazda) in Hiroshima on which he worked from 1948 to 1960. Highly practical and relatively cheap to purchase these designs proved highly popular. In 1952, Kosugi was a founder member of the pioneering Japan Industrial Designers Association (JIDA) and, in the following year, won a special award in the Mainichi Design Prize competition for his prototype design for the Janome Sewing Machine Company in Tokyo.
