Canon’s global headquarters / Shimomaruko Forest

Canon's global headquarters is located in the Shimomaruko area of Ohta ward in Tokyo. The site includes a green zone, which we call “Shimomaruko Forest,” that serves as a model site for the Canon Bird Branch Project where we carry out various activities aimed at conserving biodiversity, including birds and other living things.

What is the Shimomaruko Forest?

image

Canon Global Headquarters is located in the Shimomaruko area of Tokyo's Ohta ward.
Ohta ward is on the southern edge of Tokyo's 23 wards and is the city's largest ward. Shimomaruko is located in the southwest region of Ohta ward. The Tama River flows along the west and south sides, while residential housing and small factories fill the area surrounding the site.
Within the headquarters site we have a wide area of green space where a variety of trees and plants grow; we call it the Shimomaruko Forest. Serving as a model site for the Bird Branch Project, we conduct surveys to study the migratory patterns of birds and promote environmental improvements to bird habitat.

Observing the seasonal birds by spot censuses method

image

Since the launch of the Bird Branch Project we have conducted a monthly spot census of birds in the Shimomaruko Forest.
Under the supervision of the Wild Bird Society of Japan, we record the name of birds, the number of appearance, the place we found birds, the type of sex, and the type of bird's voice like call or songs. Since the census is taken regularly at the same time of day on the same route, we have come to know the seasonal and year-to-year changes of bird's appearance. Until now, we have found 35 species of bird in the forest.

Various birds breed their young here

Every year as spring turns to summer a variety of birds come to the Shimomaruko Forest to breed.
The Spot-billed Duck, which customarily builds its nest in the grassland near the edge of water, comes to the Shimomaruko site to raise its young at the pond in the site. Cute little ducklings swimming around with their parents is a lovely common feature in the season enjoyed each year by employees who visit the pond during their break time.

The arrival of spring brings the Barn Swallow back to the Shimomaruko forest from the south. To keep predators such as crows and snakes from approaching, swallows build a nest in spots near human activity. At the site, swallows build its nests on the lump shade under the eaves each year. Its nests are often removed by human in general, because people dislike the messiness of bird droppings all around. But we are warmly watching the healthy growth of hatchings by protecting nests and cleaning nesting areas of droppings.

Peregrine Falcons also come to Shimomaruko!!

Raptors such as the Peregrine Falcon have also been observed at the Shimomaruko Forest. Although the Peregrine Falcon is listed as an endangered species in the red data book Tokyo issued by Tokyo Metropolitan Government, one can occasionally be spotted hunting for birds and other small animals on the grounds. Raptors occupy the top of the local ecosystem pyramid and their visits to our site demonstrate that we have been able to maintain the biodiversity around this site.

Aiming to create a convenience environment for birds by installing bird baths and nest boxes

Birds visiting a bird bath and nest boxes

Aiming to create a convenience environment for birds at the urban area, we installed bird baths and nest boxes within the site.
A bird bath is a basin-shaped bathtub for birds. Birds use them to wash their feathers and remove insects. We have installed two bird baths within the Shimomaruko Forest, and now a variety of birds, including Japanese Bush Warblers, Japanese White-eyes, Japanese Tits, and Brown-eared Bulbuls, can frequently be seen preening themselves at the baths.

It is said that there are now fewer big trees or old growth trees at urban areas. We installed nest boxes around the Shimomaruko site for the sake of birds that build their nest in the hollows of such trees. We have seen Japanese Tits making use of the boxes each year to raise their chicks.

Providing opportunities for employees to learn about birds

Nest box exhibitions

Japanese Tit put their love into the construction of their nest using such materials as moss, feathers, and small twigs. Thinking it would be an opportunity for employees to become more familiar with birds, we held an exhibition of the nest boxes for Japanese Tits that we installed at the Shimomaruko Forest. It was for a short period, during the lunch break, but many employees showed interest in the exhibition, and turned out to be a good opportunity for them to think about birds and biodiversity.

* Generally a nest box is used for their breeding from spring to summer every year. It woudn't be used from fall to winter. Moreover, once birds used a nest box, they never use it for nest year. Therefore staff members of Bird Branch project clean up the inside of nest box and re-install it again.

Bird watching event for employees

We plan events specifically for employees to learn about biodiversity through various means, including the observation of birds in their habitat and their interaction with humans. At one such bird watching event, participants listened to the commentary of an instructor while walking through the Shimomaruko Forest and along the Tama River looking for common birds.
We often hear comments from participants after each event that these activities increased their interest in birds and other living things.

Presenting a unified image to the world

image

Our Visual Design team is managing the visual identity of whole Bird Branch Project activities. By using universal design in our promotional materials, including logos and color schemes, as well as websites and posters, we can share our vision irrespective of language and culture.
Through the Bird Branch Project we would like to communicate to people around the world the importance of biodiversity with the power of design.

From Shimomaruko to the world

While contemplating what Canon could do to preserve biodiversity we had an opportunity to welcome members of the Wild Bird Society of Japan to our Shimomaruko site. With one look at our Shimomaruko Forest, one of the visitors commented, “At least there are 50 species of birds here!” At first we could not quite believe it, but after surveying the area together with members of the Wild Bird Society, we noticed that there are in fact many birds around and also that we have rich nature surrounding us each day as we work.
We promote the Bird Branch Project out of a desire for people around the world to take an interest in the nature around them through birds. We hope this project will become a catalyst in raising awareness of the importance of biodiversity.
