Construction begins on a factory in Kambara, Shizuoka City, Shizuoka Prefecture. Nippon Light Metal Co.,Ltd., located next door, manufactures and develops Caustic soda, Chlorine, and Hydrogen generated by chloro‐alkali electrolysis, as well as secondary products that can be made using these substances, and we are supplied with some of the Chlorine.

Production plant No.1 established. 02_Parachlorobenzyl chloride: Production of p-Chlorobenzyl chloride was started as a raw material for the parent company, KUMIAI CHEMICAL INDUSTRY CO., LTD.

Production plant No.2 established. Chlorotoluene : plant No.2 : Production of p-Chlorotoluene/o-Chlorotoluene from Toluene began. The completion of the dignified, towering two 50-meter distillation towers is a symbol of our company and marks the first step toward further expanding Chlorotoluene sales around the world.

Increased capital to 600 million JPY.

Production plant No.3 established. P-Chlorobenzotrichloride : plant No.3 : Production of P-Chlorobenzotrichloride was started.

Tokyo office opened.

New product research for the future was started.

Production plant No.4 established. o-Toluoyl Chloride : plant No.4 : We started production of o-Toluoyl Chloride as a raw material for the parent company, KUMIAI CHEMICAL INDUSTRY CO., LTD. Currently, the plant is used for the production of other Acid chlorides.

Production plant No.5 established. Chlorobenzaldehyde : plant No.5 : Amid expectations of increased demand for Chlorotoluene derivatives as agrochemical and pharmaceutical raw materials in Japan and abroad, we completed construction of a Hydrolysis facility and began production of p-Chlorobenzaldehyde and o-Chlorobenzaldehyde in order to establish a supply system for the global market.

Increased Capital to 780 million JPY.

Production plant No.6 established. Production of Xylene derivatives was expanded. 2,5-Dichloro-p-xylene : plant No.6 : The facility began operation as a means of entering the Xylene Chlorination field and of overcoming the situation where existing Chlorination facilities were no longer able to meet demand. It has Crystallization, Filtration, and Drying processes, and our first powder products were produced. Demand for our main product, α,α'-Dichloro-p-xylene, grew steadily, as did demand for the same Xylene derivative, Isophthaloyl chloride/Terephthaloyl chloride.

Achieved ISO 9002 certification.

Production plant No.7 established. The plant was constructed to meet the rapidly increasing demand for α,α'-dichloro-p-xylene for electrical materials. Since then, the plant has been in operation to produce raw materials for high-performance materials. : plant No.7

Achieved ISO 14001 certification.
