Gunma's engagement with the environmental conservation

"Take Home Your Own Trash" Campaign
Did you know that the "Take Home Your Own Trash" campaign started in Oze? The project was initially started in 1972 and spread throughout the nation. Although this campaign promotes people to take home their own trash all year round, in June, there is also a campaign to distribute trash bags and remind people to observe the "Take Home Your Own Trash" campaign.
We encourage everyone to observe good manners and enjoy the beautiful nature.
"Industry Participation Forest Restoration" Project
Gunma Prefecture is striving to promote the "Industry Participation Forest Restoration" project with the aim to conserve and develop forests to restore the lush greenery and nature by bridging the forest owners, who have difficulty in maintaining their forests on their own, on the participation of companies and groups who are interested in restoring forests as social contributions.
The forest restoration activities conduct tree planting, cutting grass and thinning as part of training programs for company employees, activities related to the welfare of families, promotional events inviting customers, community activities and much more. There is also a certification system for those participated in the forest restoration activities using the amount of carbon dioxide absorption as a certification.
