 Eiko was discovered by Tsuji Masuda who created Parco Ikebukuro from the ailing Marubutsu Department Store.When Parco did well and expanded to a Shibuya location in 1973, Eiko designed Parco Shibuya's first 15-second commercial for the grand opening with "a tall, thin black woman, dressed in a black bikini, dancing with a very small man in a Santa Claus outfit".She became deeply involved in Parco's image.
