Daiichi Sankyo Announces Removal of Contaminated Soil Storage Facility from Site of Former Yasugawa Plant in Japan

Tokyo, Japan (April 27, 2020) – Daiichi Sankyo Company, Limited (hereafter, “Daiichi Sankyo”) today announced that it will remove a contaminated soil storage facility located on the site of its former Sankyo Yasugawa plant (hereafter, “the plant”) in Japan.


The plant began operations in 1939, manufacturing agricultural chemicals. After production ceased in 2003, it has been managed as a vacant site. In 1993, it was confirmed that mercury, which was one of the agrochemical raw materials, was distributed in the former plant site in excess of environmental standards. Daiichi Sankyo established a robust underground storage facility in line with government directives and has managed the contaminated soil appropriately.


Although there have been no reports of leakages or adverse effects on health thus far, in order to contribute to the further safety and peace of mind of the community going forward, and in accordance with the wishes of local residents, Daiichi Sankyo has decided to remove the underground storage facility. Through close consultation with the relevant stakeholders, Daiichi Sankyo will take every effort to prevent any impact on the surrounding environment during the removal process.


Daiichi Sankyo allocated a provision for environmental measures of approximately 8.2 billion yen as related expenses in the fourth quarter of fiscal 2019, which will be used to cover the cost of removal work.


Daiichi Sankyo will continue to implement environment-focused management by addressing the reduction of environmental impact and risks in its business activities.
