For garment inspection, check appearance, sewing and confirm the label items in line with Household Goods Quality Labeling.

Garment test

Appearance, sewing, and raw materials

Appearance, sewing, and raw materials

We check whether the garment have any defects. We check to see if there are left-right asymmetry,twist etc. (appearance), frayed seam, seam slippage etc. (sewing), if using a fabric that matches the garments characteristics, whether accessories such as buttons etc. with burrs and sharp projections are used etc. (material), to make sure it doesn’t interfere with wearing the garment.

Care label

Care label

Overprotective care label symbol

For textile products, it is necessary to indicate the fiber composition and care instructions in accordance with “Household Goods Quality Labeling Act” for consumers to identify the quality.
The same goes for leather clothing.
The care label symbol must be appropriate for the garment, but it is also inappropriate to indicate unnecessary weak processing.

Exaggerated misunderstanding recognition

In a case of displaying the country of origin or the garments functionality, it is necessary to indicate it in accordance with “Act against Unjustifiable Premiums and Misleading Representations”. Therefore, we check whether these indications are displayed. This is performed to prevent indications that are disadvantageous for the customers such as making the garment quality unreasonably high (indicating functionality, although functionality finishing was not processed etc.).


It is necessary to be careful not to conflict with “Act on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices”.
For example, medical effects such as “Stiff shoulder can be healed” and “Promote blood circulation” cannot be shown.
(Excluding pharmaceuticals, quasi drugs and medical devices.)

Dimensional stability and Appearance change

Dimensional stability and Appearance change

We check whether there is a problem, by washing and dry cleaning the product. The processing method basically follows the care label symbol; however, if there is an agreement with the delivery destination, that should be the priority. Even if there was no problem in the test of a single fabric, there may be a problem when making it into a garment and for that reason it is very important to actually wash it.


・The lining of the skirt and dress is showing because the dimensional change rate of
the outer fabric and lining are different.

・Bleeding due to color scheme, waviness on the seam (seam puckering), deformation, peeling of the coating, excessive shrinkage & overstretched of the dimensions.
