Comment from Koichi Yairi:
For this collaboration, I focused on the theme of “a companion that grows with your everyday life.”By customizing the main bag with small accessory items, I wanted to create something that naturally reflects each person's lifestyle and the passage of time.
The artwork expresses various scenes that extend from daily life—outdoor activities, walks, commuting to school or work, music festivals, tennis, and more.
By combining the main bag with mini accessories, users can create a personalized setup that evolves with their lifestyle—embodying the idea of a bag that grows with its owner.
