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 has been working to reduce and recycle waste with the aim of creating a ‘Zero Emission City Hiroshima’, where waste is reduced to as close to zero as possible and the impact on the environment is extremely small. As a result, the city has made great progress in waste reduction and recycling, including maintaining a low amount of waste generated per person per day among ordinance-designated cities. 

In terms of global warming countermeasures, in December 2020, the city announced its aim to achieve virtually zero GHG emissions by 2050 and is working to promote energy-saving measures and the implementation of renewable energy.

Furthermore, Hiroshima City declared a ‘Hiroshima Climate Emergency‘ in July 2022, and the ‘Hiroshima City Global Warming Prevention Action Plan’ was revised and updated in March 2023. The city shares a sense of crisis with its citizens, businesses, and all other actors, and in cooperation with the surrounding local governments in the Hiroshima Major Metropolitan Area and ICLEI, the city will make every effort to pass on the rich nature of this region to the next generation.
