Much like its close counterpart ramen, saimin was also developed as an instant noodle in 1963 by Shimoko & Sons saimin brand, better known to locals as S&S saimin. Unlike instant ramen, S&S saimin noodles require refrigeration or freezing and are not dry. The noodles are also pre-cooked, making it a ready-to-eat food by simply adding hot water with a soup base packaged separately. Instant saimin has since become a staple in many Hawaii households because of its quick and easy preparation, in addition allowing the consumer to add any toppings they desire.
