In order to protect the Earth's beautiful environment and provide a comfortable place to live, NTT is involved in cleanup activities through each of its regional offices. Although these activities were first spurred by the "Clean the Sea of Japan" campaign started by the new corporate affiliate Young Monitor, activities have grown to include not only seaside cleanup, but now extend to continuous cleanup activities at over 770 locations nationwide from cleaning up wetlands, gathering Tamagawa River cleanup assistance, and cleaning parks and tourist sites. Every year 30 to 40 thousand NTT employees participate in environmental cleanup activities. NTT supports these activities by providing the goods necessary for cleanup such as garbage bags, and plays an important role along with government and other corporations in promoting local awareness of environmental issues.
