The Merries Quality Commitment


A baby's smile signifies that they are happy and comfortable. From the birth of Merries brand in 1983 through today, we have continued to pursue gentleness on the skin and high quality --all for the sake of that smile.


More than 31 years of R&D focused on making Merries products even gentler on the skin--no wonder Merries is so well-loved in Japan and throughout the world!

The Merries commitment

  • Baby skin research and analysis is conducted together with dermatologists and pediatricians. Diaper usage habits are studied in the context of local customs, thus identifying specific local needs.
  • Only those materials which have been confirmed safe for baby's skin are used
  • Extensive pre-market checks on product safety, quality, and acceptability

 Production (quality control)

Merries' attention to detail in ensuring a peace of mind is typical of Japanese craftsmanship. We spare no effort in our quest to protect baby's delicate skin.

The Merries commitment

  • Use of the same production technology and quality control at Merries' three plants in Japan ensures the quality of each and every diaper
  • Strict hygiene management prevents any external air from the environment from entering the plant interiors. Mandatory "air showers" at the plant entrances prevent dust and dirt from being carried in.
  • Multiple checks with highly sensitive sensors during the production process prevents diaper contamination. These are also double checked again manually with human eyes as part of Merries' rigorous quality control.
  • A serial number is printed on all products so individual product information can be traced even after shipment. We believe that product responsibility continues even after product delivery!
