Picking up litter

Our staff from each department takes it in turns to volunteer to pick up litter around the company premises three times per week. This is a good opportunity to meet our neighbours and communicate across departments in the company.


Participating in environmental conservation activities

As a company member of the association for beautifying the rivers in the Koza district, we participate in activities such as safety patrols along the rivers and beautifying the river environment. Such activities include inspecting the area around the Mekujiri river (into which the rainwater which falls on the factory is discharged) and also picking up litter in this area. People from various companies get together for these activities, and it is always a good opportunity to interact with them regardless of the type of business sector or industry.


In harmony with nature

We have established a gardening club and we engage in beautification and greening activities. Around our manufacturing plant which complies with GMP, weeding and debugging are implemented. In addition, a variety of seasonal flowers are planted around the head office building to make visitors feel welcome and give a pleasant appearance. It is our aim to stay in harmony with nature by planting herbs that have a repellent effect on insects

Certified office management plant

In October 2016, we received the certificate for environmental office management awarded by Kanagawa prefecture. Currently, we are the only office which has received this certificate in the city of Zama. It is, of course, our responsibility as a company which handles chemical substances to pay due regard to its management. However, it is also important to us to recognise the influence we have on the environment and proactively examine ways of reducing the environmental impact.
