Toward a world where everyone can enjoy fashion.

A wheelchair-using friend of mine told me,
“I really want to go on vacation with my friends, but I can’t. I don’t want them to see me in diapers. I don’t want them to see me in diapers.”

A mother-fearing friend of mine told me,
“My mother, who used to be so fashionable… I can’t forget the sad look on her face when she was urged to put on diapers at the nursing home. I’ll never forget the sad look on her face when she was urged to put on a diaper at the nursing home.”

“If there were diapers that I would want to wear…”
It made me think that way.

A woman suffering from postpartum urine leakage.
Men who suffer from urine leakage due to prostate disease.
People who have lost the urge to have a bowel movement due to an accident or illness.
People who have difficulty defecating by themselves.

There are few options for diapers that we would want to wear.
There are few diaper options that we would like to wear.
There are people who have lost their freedom of mind and action.

If there are no diapers that they want to wear,
we will make them ourselves: diapers of the future that will make your heart flutter.

Our vision of the diapers of the future:
We do not stop at the pursuit of beauty and functionality.
We believe that enhancing the well-being of each and every one of us is the key to the future of diapers.
NextUD® (Next Universal Design) is what we stand for.

We are proposing the diapers of the future to the world from the perspectives of welfare, medical care, and design.
