What is KAITEKIKOUBOU?

  • Inside the factory

    The story behind its creation

    It all started with the passionate desire of an elementary school teacher who saw the children of a silkworm farm sleeping during class because they were tired. A thin thread made by a small company. A big, bold dream that doesn't match that thin thread.
    The thread of our hearts has never broken, no matter what difficulties we face, and we have been weaving our thoughts together with sincerity for approximately 120 years.
    The underwear brand "KAITEKIKOUBOU" was born, condensing Gunze's DNA and forming the basis of all of our products.

    Every single stitch is carefully crafted to provide an unprecedented level of comfort.

Reasons for comfort

1. Comfort Science Lab
Gunze's research laboratory studies the science of underwear.

  • From the perspective of physiological anthropology and ergonomics
    Pursuing the ideal underwear

    Underwear is said to be the second skin.
    The Gunze Comfort Science Lab is an Underwear Physiology Research Institute established to pursue the ideal undergarment and to scientifically research a better relationship between undergarments and the human body so that people can feel comfortable both physically and mentally.

    By measuring physiological data (physiological values) from multiple perspectives, including physiological anthropology, psychology, and ergonomics, and then scientifically verifying it, we are able to develop products that are comfortable to wear and do not put a strain on the body.

    Furthermore, we utilize the know-how of each division of Gunze, such as planning, production, and sales, to develop products that can meet all needs.

2. Three-dimensional design
Soft and comfortable to wear, but not bulky.

  • Gunze's unique three-dimensional design based on the science of body shape
    Gently envelops you, creating an exquisite fit

    KAITEKIKOUBOU has been highly praised by customers for its comfort.
    This comes from Gunze's unique three-dimensional design technology.
    By designing the garment three-dimensionally based on the actual shape of the human body, from the knitting and cutting stages onwards, the feeling of tightness (pressure) felt when wearing the garment is greatly reduced.
    It is gentle on the body and fits smoothly, creating a comfortable fit that only KAITEKIKOUBOU can provide.
    In order to minimize any discomfort to the skin when worn, the side seams between the body parts, which can be a nuisance when touching the skin, have been eliminated.This is a gentle design made possible by the three-dimensional design.
