Consideration for the local environment
Participation in environmental event "Eco-Pro"
Every year, we participate in “Eco-Pro”, one of the largest environmental events in Japan, so that our stakeholders can learn about our environmental activities. “Eco-Pro 2017” introduced eco-roads (roads that consider the natural environment), greening with local seedlings, and the introduction of renewable energy.
Tokai-Hokuriku Expwy Johana SA In order to improve the habitat of Gifu Butterfly (Ministry of the Environment: Endangered species) that lives in the neighborhood, in 2000, a nursery tree that becomes a coppice and a feeder, Himekan Mallow, will be installed in the service area. Planted. Starting in 2001, in the village forest around Sakuragaike, with local elementary school students and organizations, the Gifcho butterfly butterflying party has been set up. . In the 2017 butterfly event, about 70 gibbons were released into the sky at the castle's edge.
