The History of Nippon Kayaku Group

Nippon Kayaku has contributed the best produ cts meeting the needs of the times to society while integrating and evolving core technologies.

Nippon Kayaku Seizo Co., Ltd., the predecessor of the Nippon Kayaku Group,was established as Japan’s first private industrial explosives manufacturer in 1916 after World War I led to delays in the import and severe shortages of dynamite used for mining coal, the staple energy resource at the time.
Teikoku Senryo Seizo Co., Ltd. was established the same year to domesticate production of synthetic dyes, 90% of which were dependent on imports at the time. It was subsequently found that an intermediate products for synthetic dyes could be applied to pharmaceutical drugs, and Yamakawa Seiyaku Co., Ltd. was therefore established in 1931 and succeeded in producing the analgesic anti-inflammatory drug, ASPIRIN, in Japan for the first time.
 As employees were mobilized and resources became scarce at the later stages of the Pacific War, these three companies, which derived from the same founding group, merged and were absorbed into Nippon Kayaku Seizo Co., Ltd. in 1943 to overcome these difficulties. This formed the cornerstones of the current business: explosives, dyes, and pharmaceuticals. The company name was subsequently changed to current name of Nippon Kayaku Co., Ltd. after the war in December 1945, relaunching the Company as an integrated chemical manufacturer.

The post-war period of economic recovery spurred the construction of hydroelectric power plants to supply energy and this resulted in dramatic growth in explosives production volume. The antibiotic PENICILLIN also became the centerpiece of the pharmaceuticals business, and efforts to disseminate it contributed to the treatment and eradication of communicable diseases.
 The coal industry, which had supported the recovery, declined during the subsequent period of high growth, ushering in a new age of revolution in energy derived mainly from oil and natural gas. Demand for explosives shifted to the public works business for building infrastructure such as high-speed railways and expressways. The domestic textile industry entered its golden age around that time and the dyes business for synthetic fiber also expanded.
 The anti-cancer drug BLEO™ was also launched in the pharmaceuticals business.
 Yasusaburo Hara, the third company president, established the corporate motto of “Combined forces of our consciences, Ceaseless progress, Best products,” in 1962 when the Company nominated itself for the Deming Prize and dedicated itself to quality control. The award of the Deming Application Prize to Nippon Kayaku the next year and the subsequent continuance of TQC (Total Quality Control) activities contributed greatly to the destruction of the status quo and modernization of the Company. That spirit has been handed down to the present as the KAYAKU spirit, our corporate vision.

The Company undertook a major reorganization to respond to changes engendered by the oil crisis in the 1970s and introduced four divisions: The explosives business, the dyes business, the pharmaceuticals business, and the agrochemicals business. Nippon Kayaku subsequently overcame trials by shrinking mature businesses, streamlining, and actively investing in the pharmaceuticals business and other areas that could promise growth.
 In 1980, the corporate vision was defined as “be a company that safeguards human life and health, and continuously contributes to the human race with products and technologies that support a rich cultured lifestyle.” The Company subsequently successfully evolved the dyes business into the chemicals business, and succeeded in applying explosive technologies to the development air bag inflators, which led to the safety systems business, thereby integrating and evolving core technologies to create new businesses and products that could meet the needs of the times continuously.

The corporate vision of the KAYAKU spirit of “Continuously providing society with the best products through ceaseless progress and the combined forces of our consciences” was set forth as the goal for corporate activities in 2007, based on the corporate motto developed in 1962. This “responding to the demands of society and contributing” is the spirit that has been handed down since the Company began.
 In recent years, environmentally-friendly epoxy resins have been developed to meet the increasing need for environmental protection in the functional chemicals business. Nippon Kayaku has evolved the technologies we have cultivated since our founding as a pioneer in the fine chemicals business through the global expansion of the safety systems business as the need for automotive safety components expanded globally, and through the launch of biosimilars which promise to contribute to society by lowering the cost of healthcare. We will contribute to society and achieve steady growth as a global “Smart Chemicals Company” by providing the best products needed in each era.
