About 'Shin Ramyun Tumba'

'Shin Ramyun Tumba' is a new sensation instant noodle with a rich, creamy sauce accented with a 'deliciously spicy' kick, entwined with chewy-textured noodles. 'Tumba' refers to a spicy cream pasta using shrimp and mushrooms that became popular in South Korea around 2016. After an arranged menu featuring Shin Ramyun prepared in this Tumba style gained popularity among consumers, it was officially productized. After its launch in South Korea in September 2024, it sold 25 million units in just four months (total sales volume of bag noodles and cups in South Korea). Subsequently, it was launched in Japan in February 2025 as a bag noodle type and in April 2025 as a cup type. The creamy, slightly mild savory-spicy flavor, somewhat different from traditional Shin Ramyun, has been enthusiastically supported by Japanese consumers, achieving exceptional annual sales of 1 billion yen (total sales amount of bag noodles and cups in Japan) for a new product, and was also selected for the 'Nikkei Trendy 2025 Hit Products Best 30', generating significant反响.
