Itabashi City: Mayor Takeshi Sakamoto

In 1993, Itabashi City developed the “Ecopolis Itabashi Environmental Declaration” to create a city that coexists with the environment, and in 1995, we established the Ecopolis Center, a comprehensive facility to educate citizens about the environment and recycling. In 1999, we launched the “Itabashi City Environmental Management System” to promote the city’s environmental activities and became Tokyo’s first municipality to acquire ISO14001 certification. We have continued to promote the “Green Curtain” project, which was launched by elementary schools in the city in 2003, as a popular measure that can be taken by anyone to mitigate global warming.

In addition to these initiatives, Itabashi is taking various efforts to achieve a sustainable society through the implementation of our “Global Warming Countermeasure Action Plan” (FY 2012), “Environmental Master Plan 2025” (FY2015), and “Environmental Education Promotion Plan 2025” (FY2015). 

Overview of Itabashi City


Population: Approx. 570,000

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 570,000. 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

Through the “Environmental Master Plan,” Itabashi City developed an environmental vision that it hopes to achieve over the next 10 years. With the vision of becoming an “Ecopolis Itabashi: A smart city that links people and environment to the future,” the city set topic-based goals and is taking environmental protection measures to achieve them.

Specifically in the field of environmental education, the city developed the “Environmental Education Plan” to identify concrete actions. Based on this plan, the city aims to promote environmental education and action through the collaboration and partnerships of citizens, community groups, businesses, schools, and city government.

Since 2007, the city has been running an environmental education program, and the “Environmental Education Handbook” has been used widely in various educational scenes.

These activities have gained broad recognition. Recently, a non-profit organization that has been working with the city to develop and implement environmental education programs, received the “Global Warming Prevention Action Award,” which is awarded by the Minister of the Environment.
