​Sustainable Collection


a sustainable collection featuring Japanese traditional colors

Available in four colors: "Hiwa", "Hisoku", "Nadeshiko" and "Kurumi"


”TENCEL is soft on your skin and gentle to the environment, contributing to a healthy future.” 


In recent years, as global warming and abnormal weather conditions have raised concerns about changes in the global environment, attention has been focused on sustainable lifestyles. Our past consumer society is now being reconsidered, and a sustainable lifestyle is being incorporated into our daily necessities, food and clothing.


Our continuous effort and consideration will gradually change our future.  

And one day, sustainability will change from being something we need to be mindful about, to becoming a natural part of our lives.


K+1% strives for a rich and bright future for ourselves and our children.

With that philosphy at our core, we are pleased to announce our new sustainable collection using TENCEL, a regenerated fiber made from eucalyptus resin.


K+1% was launched in 2018 to help make the unpleasant times of a woman's period more enjoyable, with the theme "+1% to Kirei (beautiful) and Kawaii (cute)".

Our main product is our period panty, made to help for times when your skin is particularly sensitive.

The smooth and soft touch of TENCEL will embrace us in our time of need.

TENCEL absorbs moisture, prevents dampness,

and the light texture prevents the growth of bacteria, making it the perfect material for spring and summer lingerie.


Our new sustainable collection from K+1% is gentle to both our skin and the environment,  connecting our present to a better tomorrow.


Until now, our perception of organic and eco-friendly clothing seemed to lack variation in colors, and products seemed to center around colors such as beige and grey.


K+1% is proud to present our sustainable collection in four colors.

These four colors are named after traditional Japanese elements representing nature such as plants, flowers and birds.

Embrace the cultural background of eah color and what it represents, to spend each day with a positive mindset.

We should love what we wear as we love nature, so that we can love ourselves and our future.

That is the kind of lingerie we strive to create for you to wear.


For your everyday, and for your future,

Kirei(beautiful), Kawaii (cute) and Kimochi yoi (pleasant)

We strive to be a presence that adds +1% to your "K"





CUDDLE means "to hug tightly" or "to cuddle".

CUDDLE is a wear line unique to K+1% that focuses on “good texture and comfort”.

I will definitely pick it up over time,

I want to hug you tightly,

We propose clothes that are close to your daily life.
