## ■ Rethinking the "Norms" of the Cleaning Industry
In the cleaning industry, the primary role is generally considered to be "making things clean." However, while taking this as a premise, the company has focused on the "unseen value" in everyday life. The comfortable spaces and secure environments maintained through cleaning are essential elements that support our daily lives and workplaces. The company develops its business and activities with the belief that it is important to re-recognize these values within society.
While these are crucial elements, they are also entities that are hard to be aware of in our daily routines. It is exactly within the seemingly "ordinary" daily life that important values are hidden, and numerous seeds of gratitude exist.
## ■ Visualizing Value Through Education and Community Activities
The "Kizuku Project" run by the company is an educational program that nurtures children's "awareness" through litter-picking activities. It has been held 11 times so far, with about 150 participants. It will soon mark its 3rd anniversary since inception. Children who have participated show changes such as:
- Changes in awareness towards their immediate environment
- Increased interest in the people who support the community
- Realization of roles and responsibilities in everyday life
This project functions not just as an environmental beautification activity, but as an opportunity to learn how to engage with society.
## ■ Initiatives as a Company Open to the Community
Mitsunaga Building Service is also working on creating touchpoints with the community, such as opening its own office to the local community and using it as a place for interaction. By positioning corporate activities within the local community and building relationships, we aim to create sustainable value.
