Kao and Cainz Test the Introduction of Foldable Containers as Reusable Packing Material

Evaluating Their Effect on Reducing Environmental Impact and Improving Work Efficiency

From July 6, 2022, the Kao Corporation and Cainz Corporation began testing the use of foldable containers that can be used repeatedly as packing materials for products at one of the Cainz's stores in Tokyo. In addition, both companies are collaborating to evaluate the effects of utilizing foldable containers to reduce the environmental impact and improve work efficiency. Utilizing the knowledge gained through this test, Kao and Cainz aim to expand the number of stores that use foldable containers and to build it into an industry-wide initiative.



In recent years, as environmentally friendly efforts by companies have increased, Kao is taking the Yoki-Monozukuri*1 concept, cultivated by the group through its corporate activities to date, and upgrading it to ESG-driven Yoki-Monozukuri, as well as strengthening its initiatives in consideration of the environment and society. In October 2021, Cainz also formulated the Kumimachi Concept*2 to achieve carbon zero in the entire Cainz supply chain by 2050, and is contributing to carbon zero in towns that have Cainz establishments as well*3 .

Until now, recyclable corrugated cardboard has been mainly used as the material for packing products when delivering products to retailers, but, the burden of opening and disposing of the cardboard at stores and the CO2 emissions produced during the recycling process remained a challenge.

Therefore, Kao and Cainz are collaborating to test the introduction of foldable containers that can be used repeatedly, and start efforts to collect and reuse them. In addition, both companies are examining the effects of foldable containers in various situations such as delivery, display and sales, and are determining the advantages and disadvantages of using foldable containers. Moving forward, based on these results, Kao and Cainz will first expand the number of stores that use foldable containers, and in the future aim to standardize their use throughout the industry.

Main Aspects of the Initiative


Evaluation of the effect of using foldable containers as a reusable packing material


The initiative is examining how well reusable foldable containers protect products during transportation, are handled at manufacturing plants, support work efficiency at distribution bases, resolve store issues and contribute to sales. The initiative is also scrutinizing the structure of the foldable containers.

Examination period

July 6 through December 31

Implementation store

Cainz Minami-Sunamachi SUNAMO Store (the number of implementation stores is scheduled to increase)

Number of foldable containers used

About 10,000 containers/month

First Initiative Formulated as a Result of 01KAO

This is the first initiative that has been realized because of the 01KAO (Zero-One Kao), a system launched in July 2021 for all Kao Group employees to publicly solicit ideas from each employee in order to commercialize them or use them for in-house restructuring. Kao has set "maximize the power and potential of employees" as one of its policy objectives of the Mid-term Plan K25, and 01KAO plays a large role in fulfilling the objective.

In addition, the Kao Group established its ESG strategy, the Kirei Lifestyle Plan in April 2019. The foldable container initiative contributes to the key leadership action theme of "Decarbonization" in the Kirei Lifestyle Plan. Kao will continue to integrate its ESG strategy into its management practices and develop its business. It will also aim to provide better products and services for consumers and society while working toward its purpose, "To realize a Kirei World in which all life lives in harmony."
