Our Approach to Protecting the Environment

Chori handles a variety of environment-friendly materials. At the CHORI Exhibition, a trade show for apparel, the Company presents an extensive range of proprietary, environment-friendly materials in combination with other materials.

Recycled polyester fiber made from discarded plastic bottles



ECO BLUE is recycled polyester fiber made from discarded plastic bottles. It was launched in 2007 and has continued to evolve over its 15-year history. The strength of ECO BLUE lies in the Company’s ability to handle over 200 types of yarn by leveraging the solid relationships it has built with some of the world’s leading synthetic fiber manufacturers.

Environment-friendly Apparel Products

Natural Dye

Conventional grass-dyed fabrics are sensitive to perspiration and light, and their colors can fade when washed. Natural Dye is an environment-friendly apparel product that addresses these issues.
Natural residue extracted from plants, coffee, and vegetables is dyed using ingredients derived from nature.
Natural Dye can express a broad palette of colors and can dye not only natural fibers but also chemical fibers.
Moreover, the extremely low level of residual dye in the waste liquid contributes to the prevention of water and soil pollution, helping reduce the environmental burden.
Outside of Japan, demand is increasing from European and other environmentally conscious countries.

Lithium Compound Production Project

Chile, Lithium

The evaporation method commonly used to extract lithium components from brine water was associated with concerns over its significant environmental impact. In contrast, Chori has been participating in a project to produce lithium compounds through the use of a new method that enables only lithium components to be extracted from brine water, thereby maintaining the water volume of salt flats. Compared with our conventional approach, this new extraction method contributes to significant reductions in production time, and because it does not hinge on weather conditions, the production volume can be adjusted in line with market conditions.
Through such means, Chori will address the needs of the lithium-ion battery market, which we anticipate will expand even more going forward.

Environment-friendly seed sheets

Biodegradable Resin

Seed sheets are made of biodegradable resin and are ultimately decomposed by microorganisms into water and carbon dioxide. As seed sheets do not need to be collected after use, they contribute to improvements in agricultural productivity.

Environment-friendly foodstuffs

Plant-based Foods
(Plant-derived Alternative Meat)

With the global population projected to reach approximately 10 billion by 2050, there are concerns over the potential imbalance between supply and demand for protein sources such as beef and pork. At Chori, we have been focusing on soybeans, wheat, and green peas as a source of ingredients; procuring ingredients of the highest quality and safety that comply with the Non-GMO Project Standard from overseas; and supplying these ingredients to food processing companies in Japan. We are also working to promote the use of sunflower protein, cricket powder, and other new sources of protein throughout the Group. In addition, through our measures to prevent deforestation for livestock and reduce the use of water and crops, we strive to help realize a greener and more enriched global environment.

A rare, high-grade variety of ultra-long staple cotton


It is considered that the longer the fiber of cotton, the higher the quality, and giza is a rare, high-grade variety of ultra-long staple cotton.
Chori uses environment-friendly, cutting-edge farming techniques that include making full use of AI to minimize the amount of water required per day and has obtained certification under the Better Cotton Initiative.*
Going forward, we will continue to strengthen our handling of environment-friendly materials and contribute to a sustainable society.

  • *The Better Cotton Initiative is an international certification standard that aims for sustainable growth in cotton production and the cotton industry worldwide.
100% organic long-staple cotton


MILLENNIUM ORGANIC is a rare long-staple cotton grown in the Fergana Valley, located 600 meters above sea level in Uzbekistan. Grown in a climate of extreme temperatures and snowmelt from the mountains, the cotton is 100% organic and completely free of genetically modified organisms, as well as being made from ultra-white raw cotton.
Although regulations on hazardous substances have been tightened in Europe and Asia in recent years, MILLENNIUM ORGANIC has acquired the highest rank of class I in OEKO-TEXT STANDARD100, the world's highest safety standard for hazardous substances, and is thereby safe for use by infants.
