Sharp includes the idea of "symbiosis with the natural environment (harmony with nature)" under the concepts that a Green Factory, which has a high level of environmental consciousness, is expected to satisfy, and is working to maintain and restore the natural environment inside and outside its business sites.

At the Mie Plant (Taki-cho, Taki-gun, Mie Prefecture), two species of fish designated as threatened, the Japanese killifish (Oryzias latipes) and the Japanese eight-barbel loach (Lefua echigonia), are being released and reared in a reservoir on the factory grounds.
In the past, these fish were often seen in the Sana River that flows near the plant, but in recent years, their numbers have declined sharply. Sharp is working to reestablish the population in the reservoir, and intends to release them into the Sana River in the near future.

The Mie Plant is participating in activities to develop and maintain water resource protection forests* in the area around Ohsugidani Valley (Taki-gun, Mie Prefecture), which has been designated as a National Nature Reserve (protected natural area). Members of the local Miura Fishing Cooperative have been engaged in this activity to protect the headwaters since 1997, and Sharp employees have been participating in tree planting and forest development activities since fiscal 2005.
In addition, the Sharp Takamatsu Building (Takamatsu City, Kagawa Prefecture) established the Kagawa Sharp Forest as a water resource protection forest in April 2007. Each year Sharp will re-plant trees on 0.1 hectare (1,000 m²) of previously logged land in Tenma-ga-Hara, an area located upstream of the Naiba Dam, a valuable source of water for the prefecture.

* Water resource protection forests are wooded areas in and around a watershed (where a river system originates). In addition to improving the water holding capacity and the natural ability of forest soils to purify water, these forests also play a role in stabilizing river flow rates and maintaining water quality. Also know as a "green dam."
