In 1999, it established the “Itabashi City Environmental Management System” to promote its environmental activities and became Tokyo’s first municipality to acquire ISO14001 certification. The city is working to spread the “Green Curtain” project, launched by elementary schools in the city in 2003, as a popular measure that can be taken by anybody to mitigate global warming today.

In addition to these initiatives, Itabashi is making various efforts to realize a sustainable, low-carbon society in accordance with its FY 2012 plan to implement measures to mitigate global warming.

Overview of Itabashi City


Population: Approx. 550,000 (2016)

Located in the northwestern part of Tokyo’s 23 wards, Itabashi City consists largely of lowlands in its northern part and plateaus (heights) in its southern part. The lowlands are alluvial ones formed by the Arakawa River, and the plateaus constitute the northeastern edge of the Musashino Plateau. They have been eroded by tributaries heading to the Arakawa River, such as the Shakujii and Shirako Rivers, forming very hilly terrains with many slopes.Itabashi is a commercial city with a population of approximately 550,000. In the city, there are three major industries: commerce, which features shopping centers close to residential areas, urban agriculture in the Akatsuka area that borders on Saitama Prefecture, and manufacturing, which is concentrated in the areas along the Shingashi River, a tributary to the Arakawa River. All of these make Itabashi one of Tokyo’s leading industrial cities.

Environmental initiatives

In order to build a sustainable society, Itabashi City has formulated and is working to implement “the plan to promote environmental education”, reflecting its policy for environmental education. In accordance with this plan, the city has produced environmental education handbooks and other tools, and used them extensively for environmental education programs. In addition, in 1999, it put in place a program to subsidize the installation of such equipment as photovoltaic power generation systems for ordinary households. By the end of FY 2013, the number of systems installed under this plan had reached 2,522, contributing to the reduction of greenhouse gas emissions by approximately 2,000 tons-CO2.

In FY 2014, the city newly added storage battery systems and HEMS to the list of equipment covered by the program. In addition, in order to further reinforce the functions of the Ecopolis Center, it is conducting the renewal of the display equipment.
