Population by birth weight

*"Vital Statistics"(2012), Ministry of Health, Labour and Welfare

About half of babies weigh less than 3000 g when they are born.

Some 47% of babies are born below 3,000g.

In addition, babies lose weight soon after birth. Because of this, even if born at 3,000g, for several days he/she will be under 3,000g.

Select from 2 sizes!

Such a big difference in diaper size, with weight difference.

For example, if we put a "newborn baby–5,000g" diaper on a baby born at 2,700g…

Newborn–up to 5,000g

Loose, baggy diapers slide off,

making leaks a worry.

Newborn–up to 3,000g

if we put a "Newborn (Birth to 3000g)" diaper on...
Look! It fits perfectly!

Rounded fit that is not overly tight

A baby's body is shaped like a C!

It is natural that babies’ body shape is round

When a baby is first born, its body (back bone) is naturally curved like when it was in mother's womb. However it will gradually become straight during their development, especially when baby starts to walk.

It can wrap baby's body and fit perfectly to body's curve.

Tightening on the waist of toddler baby has been lessen! Gently wrap!

The secret of moony

Soft and perfectly snug

The point to prevent leakage from gaps is two types of gathers!

With two types of gathers, “Stretch fit gather” and “Flexibly stretchable gather”,

diapers are soft but fitting to guard against leakage!

Stretchable fit gather

For the most common leakage from the back! Because the whole back part of moony Air Fit flexibly stretches, it fits into gaps of babies' back and fully guards against leakage♪

Stretchable leakguard covers around the back

The point is that the whole back part is fully stretchable☆

Flexibly stretchable gather

Elastic materials help fit around the legs! So baby feels comfortable even when moving legs or walking.

The non-woven itself stretches and reduces tightness.

Secrets to more peace of mind

To consider newborns' bodies,

we have added a navel cut-out area for the damp navel area!

The navel area is cut into an arched shape so you can put the diaper on without it touching the damp navel area.
