Marudai Foods to Distribute Original Book Covers Featuring "Kunseiya" Sausage Designs and Recipes by Culinary Expert Ryuji at 200 Bookstores Nationwide

Major food manufacturer Marudai Foods Co., Ltd. (Headquarters: Takatsuki, Osaka; President: Yuji Sato), aspiring to be a company that contributes to people and society through food, has produced original book covers utilizing the packaging design of its "Kunseiya" series in a project with culinary researcher Ryuji. Distribution will begin on Tuesday, May 26, 2026, at 200 bookstores nationwide.

Project Background This project aims to enjoyably convey the appeal of the "Kunseiya" series outside of the product aisle. By turning the widely recognized product packaging into book covers, it adds a playful touch to daily reading scenes while proposing new ways to enjoy the products through recipes by Ryuji featured on the back. Furthermore, by designing it for smooth access to recipe information via a QR code, the final specification combines both design appeal as a book cover and practicality.

Features of the Kunseiya Original Book Cover 1. Design Utilizing Packaging of Three "Kunseiya" Series Products The front of the book covers features package designs from three products in the "Kunseiya" series (Kunseiya Rich Melting Cheese, Kunseiya Aged Wiener Black Pepper, and Kunseiya Aged Wiener Spicy Chorizo). While leveraging the product's own worldview and brand image, it is finished with an impactful design that makes you want to pick it up.

2. QR Code on the Back for Ryuji's Recipes The back features images of dishes from Ryuji's recipes using each product, along with a QR code that leads to a special site with the recipe information. It's a specification that allows you to enjoy the project casually, not just by using it as a book cover but by connecting paper and digital.

The Idea Behind the Project With this project, we wanted to broadly deliver the appeal of the "Kunseiya" series not only through its taste but also from the aspects of design and experience. Through a book cover that unites the joy of reading and the fun of cooking, we aim to create small discoveries and conversation starters in daily life. We will continue to work on creating new points of contact with our customers through projects that communicate product value from multiple perspectives.
