Hamamatsu City

Message from the Mayor of Hamamatsu City

Yusuke Nakano

Hamamatsu City is working towards achieving a sustainable society to address the various challenges it faces, including climate change and the transformation of its industrial structure.

In particular, decarbonization is an urgent issue, and the city is actively involved in energy policy ahead of the rest of the cities, by promoting the introduction of renewable energy, including solar power generation, which has the highest installed capacity in Japan.
As an ‘SDGs Future City’ selected by the government, the city is promoting measures that make the most of its characteristics, such as ‘Energy’, ‘Forestry’, and ‘Diversity’.

In 2022, a new Carbon Neutral Promotion Project Headquarters was established to strengthen decarbonization and energy policies and build a sustainable society. In addition to the initiatives in the city, we will further work towards the realization of a sustainable society in the world through information exchange and networking with all the cities participating in ICLEI.

Overview of Hamamatsu City

Hamamatsu City is a government ordinance-designated city, located between Tokyo and Osaka along the Pacific coast, with an area of 1,558 km² (the second-largest city in the nation) and a population of approximately 790,000 (16th in the nation). It’s a ‘microcosm of Japan’ city, blessed with a rich natural environment of sea, rivers, lakes, and mountains, and a diversity of coastal and urban areas, as well as mountainous regions.

Hamamatsu is the second-largest city in the central region of Honshu, Japan’s main island, after Nagoya. It is neither the capital of a prefecture nor a metropolitan area, but it is the only government ordinance-designated city that has achieved independent development on its own.

Hamamatsu City is one of Japan’s leading ‘manufacturing cities’ with a focus on transport equipment, and many companies from Hamamatsu have grown into world-class companies. It is also widely known both in Japan and abroad as a ‘music city’ with a concentration of musical instrument industries.

Environmental Initiatives

Hamamatsu City is not only Japan’s largest producer of solar power among all local governments in Japan, but also Japan’s largest producer of renewable energy, including wind power and biomass. It also has the largest area of FSC-certified forests in all municipalities nationwide.

As an ‘SDGs Future City’, Hamamatsu is taking advantage of these features to promote pioneering initiatives to utilise local resources, such as multicultural conviviality, sustainable forest management, and forestry promotion using the FSC forest certification system, and the promotion of Hamamatsu’s version of a smart city by introducing renewable energy.

In order to promote a wide range of activities by companies and organisations to achieve the SDGs, Hamamatsu will continue to raise awareness and promote initiatives related to the SDGs by utilising the Hamamatsu SDGs Promotion Platform and other means.

Hamamatsu City moves forward on the circular economy

In 2025, Hamamatsu City launched the Hamamatsu Circular Economy Partners (HAMACEP) program to accelerate the transition to a circular economy through public–private collaboration, supporting local businesses with networking, information sharing, and practical initiatives.

HARNESS the power of the ICLEI Network! " Governments need to give (the sense of) direction, as Business leaders we don't make the wind, we sail the boats. So policy should set the winds in the right directions if you want the boat going fast to the right harbor." Philippe Joubert Senior Advisor, World Business Council
