On August 1, 2025, we welcomed a representative named Umeda from Koyo Co., Ltd. for an online study session titled “Understanding Diaper Features: Koyo’s Only One Care.”
There are many types of diapers, and features such as shape, materials, absorbent cores and application methods vary by manufacturer and product.
In this session, the manufacturer directly introduced the features and design ideas behind Only One Care, Koyo’s adult disposable diaper range.
Learning about the thinking behind product development and the ideas incorporated into each product—details that can be difficult to understand from a catalog alone—helped deepen our knowledge of diapers.
Thank you to the Koyo representative who spoke and everyone who attended.
