Environmental communication activities

Contributing to preservation of the regional environment

Hamamatsu Photonics has always recognized the importance of a healthy and flourishing natural environment. As part of its efforts to promote a greener environment in the region, the Company carries out tree-planting activities. In addition, we are planting an acorn to make a forest on the company premises.

Clean-up activities in line with the Biodiversity Hamamatsu Strategy

As part of its efforts to preserve biodiversity, Hamamatsu Photonics participates in and publicizes the Hamamatsu Biodiversity Strategy, conducting environmental maintenance activities around its business locations and elsewhere in the city and prefecture. We participate in the Lake Hamana Cleanup Campaign, maintaining biodiversity in the region to preserve a flourishing natural environment for the future. During the period under review, Hamamatsu Photonics conducted cleanup activities around its business locations 12 times, with 529 employees participating in total. In addition, we are planting an acorn to make a forest on the company premises.

Happy memorial trees


As part of its activities to promote biodiversity and raise awareness of environmental issues, in October 2011 Hamamatsu Photonics began distributing “Happy Memorial Trees” to employees who bought a house or were married. To further encourage employees to grow trees at home, in October 2014 the Company expanded the program to include employees who enrolled a child in primary school. This program has proven valuable in raising environmental awareness among employees and their families. The photos shown here were provided by employees in commemoration of tree planting.


Hamamatsu Photonics is committed to the beautification, maintenance and management of the environment. We plant trees on the grounds of each business location and create “green curtains” that flourish in the summer.


Collection of used toothbrushes

In FY2019 the Company began a program to collect used toothbrushes. An outside organization awards us points according to the amount of toothbrushes collected by weight; these points are then converted into funds contributed to activities in the community. Although this program has barely started, Hamamatsu Photonics employees have already contributed a total of 16 kg of used toothbrushes.
