Itabashi City

Message from the Mayor of Itabashi City 

Takeshi Sakamoto

In 1993, Itabashi City declared itself as ‘Ecopolis – Itabashi Environmental City’ to create a city where people and the environment coexist in harmony. We, the city and our citizens, expressed our commitment to the global environment, both nationally and internationally, and to striving to protect the environment in our daily lives.

In 1994, the Itabashi Botanical Gardens and the Penang Botanical Gardens in Malaysia signed a ‘Joint Declaration of Friendship’, which led to the opening of the Itabashi Botanical Gardens, which reproduces the tropical rainforests of Southeast Asia, and in 1995, the Ecopolis Centre was established as a comprehensive educational center for environmental and recycling.
In 2003, the ‘Green Curtain’ was implemented in primary schools in the city, and the initiative spread to the whole of Itabashi and then to the rest of the country.

In 2022, we announced Zero Carbon Itabashi 2050, which aims to reduce greenhouse gas emissions to net zero by 2050 and to create a Zero Carbon City. To promote smart cities that connect people and greenery to the future and build a sustainable society, we have declared a climate emergency and are working in partnership and collaboration with all actors to encourage voluntary behavioral change in society as a whole and to achieve net zero carbon emissions by 2050 through initiatives that harmonize ecology, energy, and the economy.

Overview of Itabashi City

Itabashi City is located in the northwestern part of Tokyo’s 23 wards, and is formed by the alluvial lowlands to the north and the Musahino Plateau to the south, with rich nature remaining on the cliff line between the lowlands and the plateau.
The city is blessed with rich nature, including the Arakawa River with its vast riverbed, the Akatsuka Forest, which retains the atmosphere of Musashino, and the Shakujii River with its beautiful rows of cherry blossom trees.

Itabashi is a residential city with a population of about 582,000. The city has one of the highest concentrations of industry in Tokyo, including along the Shingashi River (a tributary of the Arakawa River), as well as commerce centered on neighboring shopping malls and urban agriculture in the Akatsuka area near the Saitama Prefecture border, making it one of the major industrial cities in Tokyo.
