MHI Group Employees and Family Members
Participate in Annual Voluntary Cleaning Activities
in Tokyo, including Komazawa Olympic Park


Since 2008, each year members of Mitsubishi Heavy Industries, Ltd.’s (MHI) Group companies have undertaken voluntary cleaning activities in their local areas in line with the Company’s CSR (corporate social responsibility) Action Guidelines for forging solid ties both with the Earth and with society at large. In the 2014 business year, activities of this nature took place close to 200 times in locations all around Japan, with a total of some 7,700 employees and their family members participating. The overriding aim of this initiative is to instill ever-greater awareness of the need for environmental protection measures and inspire contributions to local communities.

Nature observation conducted by the Komazawa Olympic Park management staff

In conjunction with this ongoing program, on October 31 (Sat) cleaning activities, combined with nature observation, took place at two locations in Tokyo: the Headquarters Branch of the Mitsubishi Heavy Industries Labor Union and Komazawa Olympic Park, which is situated close to Company housing. The day’s activities were carried out with cooperation from the Tokyo Metropolitan Park Association.

In all, a total of 153 Group employees and family members participated. By the end of the day, they reflected on their good deed in different ways. Some participants said they now felt an even closer attachment to the park, while others expressed gratitude at how the park they frequently use is always kept clean. Other participants cited their enjoyment at being able to join in together with their family members, and parents in particular said the cleaning work was a good opportunity for their children to learn about the environment and make a meaningful social contribution.
