A limited-time collaboration campaign between Sumikko Gurashi and Marugame Seimen will be held at Marugame Seimen stores nationwide from July 14, 2026. A total of four collaboration projects will be developed, including the "Marutto Wakuwaku Udon BOX", udon bills with newly drawn designs, and original goods.
The Inspiration Behind the Collaboration
"Sumikko Gurashi" is a character created in 2012 with the keyword "This is where I feel calm." The characters and stories are not only cute, but also slightly negative and surreal, making them popular among a wide range of people.
Collaboration Projects
In this campaign, we will develop a total of four collaboration projects, including the collaboration product "Marutto Wakuwaku Udon BOX", which is a box of cold udon noodles and colorful side dishes such as shrimp tempura, octopus wiener, and fried chicken, so you can enjoy a picnic with Sumikko and friends, original udon tags with a limited design drawn only for this time, and original goods that you can receive with the purchase of eligible products.
As one of the collaboration projects, "Marutto Wakuwaku Udon BOX" is now available. This is a limited-time product that can be enjoyed not only when eating in the store, but also when going out during summer vacation or eating at home.
Special SNS Project
Furthermore, if you order a cup of your favorite udon and "Marugame Udonatsu," you will receive an original collaboration, and a SNS project will also be held during the period. During the target period, 100 people who follow Marugame Seimen's official X account and meet the specified application conditions will be randomly selected to receive an original cold bag with a collaboration design of "Marugame Seimen x Sumikko Gurashi".
This is a special project only available this summer, a collaboration between Marugame Seimen and Sumikko Gurashi.
