​Sustainable Collection


A sustainable collection that incorporates traditional Japanese colors based on the environmentally friendly natural material Tencel.

"Be kind to your skin, your everyday life, and your future." 

K+1% (ケープラスワンパーセント) 女性用下着・ランジェリー・サニタリーショーツ・サステナブル

Recently, as changes in the global environment are becoming more of an issue due to global warming and abnormal weather, sustainable lifestyles are attracting attention, and by incorporating them into daily necessities, food culture, and clothing, traditional consumption can be reduced. Society is being reconsidered.

The fashion industry has a high impact on environmental destruction, such as polluted water and greenhouse gases generated in the process of making clothes.  

Is it possible to not only reduce the consumption of clothing, but also to gradually improve the selection of materials in the first place?

With this in mind, various brands are working on sustainable fashion.


With small efforts and consideration, the future (Ashita) will gradually change into a pleasant day.

And someday, sustainability will change from something we strive for to something we take for granted.


K+1% wants us and our children to have a brighter and richer future.

With this in mind, we have added a new sustainable collection that uses 95% recycled fiber, Tencel.



TENCEL is not a synthetic fiber made from petroleum, but is manufactured through chemical processing.

The manufacturing process uses much less water, chemicals and energy than other fibers such as organic cotton

It is also a truly sustainable fiber that is strong and long-lasting.


Tencel, which is derived from plants, is highly absorbent and has the effect of suppressing the growth of bacteria, making it recommended for people with sensitive skin that tends to sweat easily.

And the number one feature is its texture.

It has melt-in-your-mouth softness and PU (polyurethane) content that makes it stretch well.

It's so smooth and comfortable that you won't be able to take it off once you put it on.  

K+1% sustainable collection is available in 4 colors.

These four colors have the names of ancient Japanese colors named after nature such as plants, flowers, and birds.

Enjoy every day while feeling the background of each one,

I want you to wear lingerie that makes you love your body as much as you love nature.



K+1% has been around since the brand's launch with the theme of "beautiful and cute +1%"

Always keep in mind the menstrual week when women's feelings and skin are sensitive,

We create lingerie that is made from soft materials and is gentle on the skin, allowing you to wear it as the closest underwear to your skin.

We have proposed colors, materials, and designs that will make you more fun and happy.
