Design for Ethical

The reason why we make the design loved over 10 years


KUDEN doesn’t like disposal design and fashion. Like kimono, we like the design loved over 10 years.

KUDEN aim for design you can use over 10 years  = long life design , not  a short cycle fashion followed the trend.

Our long life means not only for shape and about fashion.

We consider about environment and people related our production, put value on how/where/who make it, and even making such a system to offer you is our “design”.


Why our design is ethical


Not consuming design mean factory can sew same shape 

If our design is not disposal one like followed the trend, sewing factory can make same shape clothes. It means sewing factory can make more high quality one.


Accumulate the technique and experience for clothes, factory can reduce sewing time and burden

By sewing same clothes, factory can accumulate the technique, experience and understands for that clothes so they cut their time and burden for work.

The process our ethical design is born
