Marugame Seimen, the popular Sanuki udon chain, is teaming up with the beloved character series Sumikko Gurashi for a limited-time collaboration starting July 14, 2026. This fun campaign brings together Marugame Seimen’s freshly made udon and the charming world of Sumikko Gurashi to create a unique dining experience that families can enjoy throughout the summer.
This collaboration is perfect for families looking to add excitement to their summer meals, especially during the busy school vacation period when preparing lunch can be a challenge. The campaign offers special menu items and original merchandise that bring smiles to both children and adults.
About the Collaboration
The campaign features four exciting collaboration projects designed to make mealtime more fun and memorable. Highlights include a special udon lunch box, collectible udon tickets with exclusive Sumikko Gurashi designs, original goods giveaways, and an SNS campaign with chances to win unique prizes.
Highlights
- Limited-edition “Marutto Waku Waku Udon BOX” with colorful side dishes inspired by Sumikko Gurashi characters, perfect for picnics or home meals.
- Original 3D placemat and character picks included with the udon box to enhance the dining experience.
- Exclusive collectible udon tickets featuring original Sumikko Gurashi artwork, released in two phases during the campaign.
- Special giveaways of original coasters and bag clips when ordering udon with Marugame Udon donuts, available in two phases.
- SNS campaign offering a chance to win original collaboration insulated bags by following Marugame Seimen’s official X account and meeting entry conditions.
The “Marutto Waku Waku Udon BOX” is carefully crafted with fresh udon noodles made to order, paired with vegetable-rich side dishes like spinach and broccoli paste representing grass, and carrot rapé mimicking a picnic sheet. The box also includes popular items such as shrimp tempura, fried chicken, and octopus-shaped sausages, making it a balanced and enjoyable meal for all ages. This box is priced at ¥690 (tax included).
Collectible udon tickets are given with each udon bowl purchase and feature exclusive designs released in two waves: the first from July 14 to August 3, and the second from August 4 to August 31. Alongside, ordering udon and a Marugame donut during these periods grants customers original coasters or bag clips featuring Sumikko Gurashi illustrations, adding to the fun.
Additionally, the SNS campaign runs from July 14 to July 18, where 100 winners will receive a special collaboration insulated bag. A second SNS campaign is planned later in the summer.
