“Making Oita Beautiful with Green Tea.”

Around the Tade-hara wetland in Aso-Kuju National Park, where magnificent scenery can be viewed, we conducted activities to eradicate Rudbeckia laciniata, which has strong reproductive capabilities and poses serious concerns for ecosystem impact. Approximately 50 people, including general participants, local government officials, and our employees, collaborated on environmental education and wetland conservation activities, sharing the importance of environmental protection.
