Ando first came up with this idea of cup-style noodles while he was staying in the US. He was visiting the country in the hope of expanding his instant ramen business overseas. He was inspired when he saw an American eat hit instant noodles. The man broke the noodles into pieces, put them in a paper cup, and poured hot water over them, then ate them using a fork. Ando went back to his hotel room and tried making his instant ramen in the same way, but the cup became too hot to hold. And he didn’t like the smell of the paper. IN1971 Ando’s company succeeded in developing the first cup-style boodles, which became very popular both in Japan and overseas because they were so delicious and easy to prepare.
