Company Information

TOP MESSAGE

From its beginnings in 1926 as a trading company specializing in chemicals, Kusumoto Chemicals has grown its business not only in Japan but also globally, expanding into the manufacture and sales of the coatings additive, DISPARLON, and sales of ETAC environmental test chambers.

The current social climate is affected by various destabilizing factors, including the weak yen, the Chinese economy, conflicts in various regions, and the policies of foreign governments.

Now is the time for us to build a solid foundation and embrace the challenge of new sustainable technologies and fields for the next era.
