Sumikko Gurashi and Marugame Udon are teaming up for a limited-time collaboration campaign starting July 14, 2026, at Marugame Udon locations nationwide. The collaboration includes four projects: the “Marutto Wakuwaku Udon BOX,” newly designed udon tickets, original goods, and an SNS campaign.

About Sumikko Gurashi
Sumikko Gurashi is a character series that debuted in 2012 with the keyword “I’m comfortable here.” The characters are not just cute but also slightly negative and surreal, which has won them a broad fanbase. Many Japanese people can relate to wanting to sit in the corner of a train or café, and the Sumikko characters embody that feeling.
Marutto Wakuwaku Udon BOX
The “Marutto Wakuwaku Udon BOX” is a collaboration product that lets customers enjoy a picnic-like experience with cold udon and a colorful assortment of sides including shrimp tempura, octopus sausage, and chicken karaage. The box is designed to look like a picnic outing with Sumikko characters, using spinach and broccoli paste for grass, carrot rape for a picnic sheet, and flower-shaped kamaboko. It also comes with an original 3D placemat and pick. Price is 690 yen (tax included). Available from July 14 to August 31, 2026, nationwide.

Limited-Edition Udon Tickets
Additionally, the regular “udon ticket” given with each bowl of udon will feature limited-edition Sumikko Gurashi designs with newly drawn illustrations. Two different designs will be released in two phases.

Original Goods and SNS Campaign
Furthermore, customers who order any udon and a “Marugame Udonatsu” will receive original collaboration goods. During the campaign period, an SNS campaign will also be held. By following the official Marugame Udon X account and meeting the entry conditions, 100 winners will be selected by lottery to receive an original collaboration cooler bag.

This special collaboration between Marugame Udon and Sumikko Gurashi is a unique summer event.
