The stonewall exterior was the outcome of communicating with our local community when we constructed our industrial waste disposal facility. The stonewall exterior epitomizes our expectation to be an environmentally friendly plant that blends in with nature. Because Mt. Sefuri does not have large stones that could be used to construct the wall, we gradually gathered stones from elsewhere for the past forty years. The stonewall has finally be completed and surrounds the entire facility.

As part of Oshima Industry’s policy to conserve nature, we have begun keeping Japanese honeybees. The project's primary objective is to pollinate fruit and flowers, which will enrich nature at Sefuri's forest. We are constantly learning as we engage in this project and have recently begun planting blueberries, peach trees, and other fruits to create a forest abundant in nature.

We have reclaimed nearby land and planted broad-leaf trees, deciduous trees, and fruit trees to transform the evergreen mountain into an environment where visitors can experience all four seasons. Each sapling is cared for delicately with the aspiration to beautify Sefuri’s scenery 50 or even 100 years in the future.

Oshima Industry is grateful to Sefuri's nature for providing a sustainable environment to operate the plant, and we are also grateful for our local community. We express this gratitude by hiring locally. Residents interested in recycling contribute to the recycling process. Our plant continues to operate everyday because of the vibrant energy of our local community.

Although still in the planning stages, Oshima Industry is conceptualizing innovations that are befitting of a recycling plant. Some of our ideas include creating constructs deep in the forest that unite people with nature and building parks brimming greenery on reclaimed land. Oshima Industry always seeks and aspires to create a better future that brings smiles and joy to people.
