Hiroshima City

Message from the Mayor of Hiroshima City 

Kazumi Matsui

On August 6, 1945, the first atomic bomb in the history of mankind was dropped on the city of Hiroshima, killing many precious lives and leaving the city in ruins. Since then, the city has undergone a remarkable recovery and is now a core city in the Chugoku and Shikoku regions.

We, the people of today, should be grateful for the efforts of our predecessors in rebuilding Hiroshima into the beautiful city that it is today, and we should pass on to future generations the rich natural environment and comfortable urban lifestyle. In other words, Hiroshima must become a city that we can be proud to show the world.

Hiroshima will continue to promote this kind of urban development and, by taking advantage of its global fame, will work to solve various global-scale environmental problems, including the common problem of global warming, in cooperation with other cities around the world through such means as ICLEI. 

Overview of Hiroshima City

Hiroshima City, located in the western part of Hiroshima Prefecture, is surrounded by lush green mountains and hills with the Chugoku Mountains in the background, and the scenic Seto Inland Sea to the south. The city is blessed with rich nature and a mild climate, with six rivers flowing through the city centre, the Ota River as their source, forming a unique landscape known as the ‘City of Water.’

Hiroshima City has the largest population in the Chugoku and Shikoku regions, and is home to a large concentration of national government agencies and corporate branches, making it a regional hub that leads the region in administrative, industrial, and economic development.

Environmental Initiatives 

Hiroshima City is advancing waste reduction and resource recycling initiatives to achieve its vision of “Zero Emission City Hiroshima,” which seeks to minimize waste generation and create a society with minimal environmental impact.  As a result of these efforts, the amount of waste generated per person per day remains among the lowest levels of Japan’s designated cities, demonstrating steady progress in waste reduction and resource recovery. Furthermore, in April 2023, Hiroshima enacted the “Hiroshima City Food Loss Reduction Promotion Ordinance,” strengthening its initiatives to foster a circular economy.

To advance the transition to a decarbonized society, Hiroshima announced its commitment in December 2020 to achieving net-zero greenhouse gas emissions by 2050. The City has since promoted energy efficiency measures and the wider deployment of renewable energy.

In July 2022, Hiroshima issued the Hiroshima Climate Emergency Declaration, and in March 2023, revised its Global Warming Countermeasures Action Plan. By fostering a shared sense of urgency among citizens, businesses, and other stakeholders, and by working closely with neighboring local governments in the Hiroshima Metropolitan Area and ICLEI, the City is striving to pass on the region’s rich natural environment to future generations.
