This project originated from a bean paste factory that had primarily focused on OEM production but decided to launch its own brand as a new business venture. The key challenge was how to approach B2C customers, in addition to its traditional B2B clients, and convert that into sustainable sales. In contemporary Japan, demand for Western-style confectionery has been growing, particularly among younger generations, while traditional Japanese sweets (wagashi) are often perceived as something enjoyed mainly by the elderly. To attract not only existing wagashi enthusiasts but also consumers unfamiliar with these confections, it was essential to introduce a sense of freshness and novelty. To achieve this, we broke away from the conventional image of yokan packaging, which has traditionally leaned toward solemn and formal designs. Instead, we developed packaging that is simple, casual, and visually engaging. Hand-drawn illustrations of the natural ingredients highlight freshness and an organic appeal, while the warm and rustic design evokes a sense of nostalgia, creating a comforting and joyful teatime atmosphere. By using the charm and vibrancy of the packaging as an entry point, we successfully reached consumers who had never before tried yokan or sweet bean paste, introducing them to its delicious taste and the broader culture of traditional Japanese confectionery. The product also gained strong traction as a gift item, resulting in sales that far exceeded initial expectations. Through this brand, the company’s longstanding philosophy of craftsmanship and dedication to traditional techniques has been conveyed to a wide audience, leading to recognition both domestically and internationally, including multiple prestigious design awards.
