Daio Paper Corporation was established in Ehime Prefecture in 1943 as a manufacturer of newsprint and containerboard. The Company subsequently expanded into the paper business and the household paper business with consumer goods such as facial tissue and toilet tissue, transforming into a full-range paper manufacturer. By leveraging the brand power and the sales channels developed through its household paper business, Daio Paper entered the absorbent products business with baby disposable diapers. Thereafter, Daio Paper embarked on a full-scale expansion into overseas markets through the establishment of baby disposable diaper production factories, first in Thailand in January 2011 and subsequently in China and Indonesia, forming a unique business portfolio.
