■ Background of Implementation Tsuruya Department Store, a leading long-established department store representing Kumamoto, has traditionally collected customer feedback through visitor surveys. However, they faced challenges such as: - Difficulty in quantitatively grasping visitor preferences and purchase motivations - Inability to visualize information contact pathways

In light of this, they decided to implement a digital diagnostic initiative using "Croissant" for the 2026 White Day event "Cookie Hyakkaten," with the aim of promoting visits and purchases among women in their 20s to 30s and acquiring data.

■ Campaign Overview This campaign involved the deployment of two content pieces designed to engage customers before and after their visit.

### ① Cookie Diagnostic (February 25th - March 10th) - Classified cookie types based on 5 questions - Guided users from the result screen to EC products - Designed SNS sharing pathways - Announced online, mainly through Instagram

### ② LINE Purchase Survey (March 11th - March 17th) - Distributed QR codes to purchasers to encourage responses - Increased participation rates through prize draws
