Exceptional quality

Only top-quality materials are used for the production of Japanese diapers; therefore, the cases of diaper rash or dermatitis are especially rare even though the baby’s skin is sensitive.

Closer to nature

Only ecologically clean and safe materials which do not contain formaldehyde, phthalates and chlorine compounds are used in production; no unnecessary additives such as aromas or lotions (even less so synthetic ones) are used.

Why Japanese diapers are so special?

Soft, fluffy and breathing

Touch Japanese diapers and you will make sure that the quality of the even most popular diapers manufactured in West Europe fall far short of Japanese ones. The fabric of the internal layer felted from extremely thin fibers is very soft, fluffy and absorbs liquid quickly; therefore, the baby’s bum stays dry.

No “chemical” odour

An exceptional feature of Japanese diapers: they have no “chemical” odour which becomes especially pungent when diapers are full. Such odour-emitting substances or aromas for masking unpleasant smells are not used for the production of Japanese diapers.

Thin and soft

We are used to thinking that ecological diapers are thick and stiff; however, thickness of Japanese diapers for newborns is merely 3 mm but their liquid-absorbing characteristics are excellent. They are thin and soft, do not pinch or rub sensitive skin and this lets the baby feel not only dry but also comfortable.

Frequently Asked Questions About Japanese Diapers

What is the difference between Merries, Moony and Goo.N diapers?

Products of different manufacturers of the Japanese diapers have more similarities than differences. The common feature of these diapers is the quality of the materials and construction. The differences are in the details. Here we will provide our opinion and opinion of our clients about the differences among these diapers.

MERRIES are somewhat larger and have higher pleats (as compared to the analogical sizes of other diaper manufacturers), and therefore are suitable for rounder babies. Moreover, according to our clients, they are especially air permeable and allow for outwards evaporation of the moisture. In our opinion, their inner layer is the lightest.

GOO.N is an economical version of the high quality diapers, which are somewhat thicker and absorb better. Their surface is enriched with vitamin E and anions (which repel the bacteria). These diapers are especially suitable for babies with sensitive />

New generation MOONY diapers are the thinnest and have a unique construction. All MOONY elements are developed to the smallest details – from the inner layer to the protective pleats. These diapers are the most popular. However, keep in mind that their pleats are somewhat lower than those of MERRIES and GOO.N.

What is the difference between the Japanese and Western diapers?

Most of the Western diapers do not compare in quality to the ones produced in Japan. Much more expensive and qualitative materials are used in manufacturing of the Japanese diapers, while the control of the manufacturing process of the diapers is performed by the governmental institutions.

Japanese diapers are made only of ecologically pure materials. They do not contain optic bleach, formaldehyde, phthalate, chlorine compounds, synthetic aromas, petroleum lotions and toxins – materials, the use of which in the production of the Western diapers is not strictly limited.

The absorbing layer stretches through the entire length and width of a diaper, therefore the chance of leakage is significantly lower. If you clench a Japanese diaper in your fist it feels like a thicker flannel strip instead of a piece of paper. Due to this softness, no hard edges are formed in the folding areas, which would otherwise rub against a baby’s legs

What materials are used in production of the Japanese diapers?

Top layer is made of felt gentle microfiber textile.

Inner absorbing layer is made of palm wood fibres whitened by the use of bleachless technology and polymeric superabsorbent granules.

Outer layer is made of air permeable impregnated non-woven textile and/or polyolephine film.

Stickers and the adhesive tape is also made of air permeable/perforated polyolephine, for the elastics – synthetic or natural rubber is used.

Every manufacturer has its own technological secrets, however the common unique feature of MOONY, MERRIES and GOO.N diapers is the quality and ecological purity of the materials. In order to avoid allergic reactions, colouring agents are used in moderation only in a top layer, and they contain no fragrances or lotions altogether (only GOO.N inner layer is enriched with vitamin E).

Do the manufacturers of the Japanese diapers have an ecological diaper certification?

Although the European Union has the ecological product labelling system – EU Ecolable (, the labelling rules have not been yet approved. However, in the absence of them, the manufacturing process of the Japanese diapers MOONY, MERRIES and GOO.N is certified by the international standardisation organisation ISO (quality management certificate ISO 9001 and environmental management certificate ISO 14001). This means that high quality standards and environmental standards were complied with at all stages of production of these diapers.

Moreover, MOONY diapers are labelled with an ECO CHARMING mark – this is a mark used by the UNICHARM corporation to label products meeting the highest quality and environmental safety requirements.

What according to the Japanese are ecological products?

For the Japanese ecology is first of all a relationship with nature, and their view of it is rather complex.

In order for a product to be considered to be ecological, it must comply with three criteria:

1) be safe for humans;
2) effect on nature during its production must be minimal;
3) its decomposition after use (utilisation) must have a minimal effect on the environment.

In other words, it is not sufficient for a product to meet only one of the criteria: if a product is safe for humans, but during its manufacture nature is being harmed, it will not be considered to be ecological.

Therefore, only highest quality and ecologically pure materials are used to manufacture the Japanese diapers. They try to use a minimum amount of raw materials and resort to the nature-friendly technologies (for example, the Japanese rejected the use of chlorine as bleach in the manufacturing of the diapers already in 1998).

Is polymeric superabsorbent an ecological material?

Superabsorbent polymer is a material used in the absorbing layer of the diapers. These polymers are absolutely safe for both the children and nature, are biologically degradable into water, carbon dioxide and organic materials, without any toxic or biological effect to the soil. Some believe that “natural absorbents” (for example corn starch) are more eco-friendly materials, however it is only a fable: according to the National Geographic, the greatest impact on the eco-balance of the Earth is caused by nothing other than the agriculture, therefore, wishing to contribute to the ecology, one must limit usage of goods, which use agricultural products as raw materials.

Moreover, these polymers contribute to using less wood pulp in an absorbing layer (less trees are cut down), while the diapers become thinner and lighter: less fuel is used for their transportation and less CO2 is emitted into the atmosphere.

One may wonder why is wood pulp still used? Without this material polymers form a solid “lump”, which is air and warmth impermeable, and because of which the baby’s bottom will become wet and irritated. Therefore balance of the two materials is needed to prevent this issue.

How fast do Japanese diapers decompose?

MOONY manufacturer UNICHARM states that their new generation diapers decompose 30% faster than the previous model of these diapers. They base this statement on the fact that less materials are used for production of these diapers. There are no standard methods or indicators, which would allow to evaluate the speed of decomposition of a commercial product, which highly depends on the environmental factors: air temperature, precipitation, bacteria. In our opinion, any statements about “faster” decomposition are rather advertising ticks than objective statements based on the facts.
