An adult diaper is a disposable undergarment worn by individuals suffering from chronic health conditions. It assists in preventing leaks due to urinary and fecal incontinence. It is manufactured using polyacrylate granules, polythene films, breathable fabrics and super-absorbent chemicals. The diapers are commonly available in the pad, flat and pant-based variants. They are widely used by adults experiencing mobility impairment, incontinence, diarrhea and dementia to avoid stains and reducing the anxiety associated with insufficient bladder control. These diapers absorb liquids in large volumes and assist in minimizing the odors. These diapers are also utilized in the medical industry for patients as they have higher absorbent capacities.

The Japanese adult diaper market is primarily being driven by the rising geriatric population, which is highly prone to severe incontinence. Various product innovations, such as the introduction of flushable adult diapers to enhance the convenience for nursing and healthcare providers, are providing a thrust to the market growth. Additionally, increasing consumer awareness regarding maintaining adequate personal hygiene and the widespread product utilization for patients in hospitals with chronic diseases are positively impacting the market growth. Product manufacturers are also developing skin-friendly and biodegradable variants produced using organic and natural raw materials for enhanced comfort for the wearer. Other factors, including the increasing working population, along with convenient product availability across various e-commerce platforms, are anticipated to drive the market growth across the country.
