What is "Onepon," the Rakuten Annual Ranking No. 1 product?
"Onepon" is a bedwetting pants brand born with the aim of creating experiences where bedwetting is viewed not as a failure but as a natural event in the process of growth. Its product design, which combines functionality and aesthetic appeal, has been well-received, securing the No. 1 spot in Rakuten Ichiba's annual ranking for two consecutive years, gaining high recognition and evaluation in the baby fashion field.
Brand's First "Paw Patrol™" Collaboration
The "Paw Patrol™" collaboration product to be released this time is "Onepon's" first IP collaboration product. By incorporating the world of "Paw Patrol™," which is highly popular worldwide, the aim was to create a product with a design that children will want to wear, making it a positive experience for parents and children.
■ Participatory product development created with users
"Onepon" adopts a participatory development style that reflects user feedback through customer surveys in product development. For this product, multiple design proposals were presented, and the design that garnered support through voting was commercialized.
Additionally, general recruitment for product models was conducted via social media, and all applicants were featured on the product page and landing page. The experience of users being involved in the product creation process leads to empathy for the brand and fan formation.
Opening of "Oeuf Soleil" Official E-commerce Site
Coinciding with the launch of this product, Product Arcs (Editor's Note: Original text likely meant 'forest Inc.' based on context) has opened the official "Oeuf Soleil" e-commerce site. "makeshop byGMO" was adopted for e-commerce construction, and the product landing pages and purchase flows have been smoothly arranged. The deciding factors for its introduction were the availability of human support for consultation when operational issues arise, and comprehensive practical support through BPO, which allows a small team to focus on customer communication and product development.
Moving forward, the proprietary e-commerce site will be the main pillar, with exclusive items and collaboration products, like this one, to be sequentially rolled out.
