NEC Nature Quest in Shiba Park

The travel distance of Parantica sita butterflies is over 2,000 km.

Making a garden for travelling Parantica sita butterflies

Since FY2011, we have held lunch time gardening and family events on holidays in Minato Ward of Tokyo where the NEC headquarters building is located to create the "Biodiversity Garden" under the slogan "Habitat for Parantica sita butterflies in Shiba Park".

Many NEC Group employees and their families participate in these long-term activities to encourage natural growth revegetation and bring back organisms that once inhabited there, and enjoy learning about local nature and geological history.
This activity received the 49th Tokyo Metropolitan Park Association Award, Encouragement Prize (Volunteer Category) in 2014.

NEC Group's Goal of Biodiversity Conservation and Contributions to Communities

Many butterflies can be seen in urban areas.
Parantica sita butterflies are famous as a travelling butterfly. They travel from Taiwan and Okinawa to Kyushu and Honshu across the sea in spring for breeding, spend summer in the plateau areas in Honshu, then travel back to the south in fall.

Tokyo is on their migration route, and they are seen in Hibiya Park and Shunjuku Gyoen.
We are conducting activities to create an environment where Parantica sita butterflies can visit through biodiversity garden maintenance in Shiba Park.

This activity contributes to local environment beautification and biodiversity conservation in cooperation with local governments, NPOs and local communities while contributing to community development where employees and their families come in contact with the surrounding nature and people in the community enjoy.
