Major Industry Distribution

Industries with specific characteristics are located in four areas of the city: the waterfront, urban, inland and hilly areas. With major road development, transportation in the city and the wider surrounding areas has become more convenient, and the city is well connected to international transportation systems, such as the Kansai International Airport and the Sakai-Semboku Port.
Also, Sakai is blessed with academic institutions and smaller business support facilities, including Osaka Prefecture University, Kansai University and Sakai City Industrial Promotion Center. It has an easy access to the Technology Research Institute of Osaka Prefecture and others in neighboring municipalities are also easily accessible.

Waterfront Area

In this industrial area there are both large scale manufacturing businesses and small and medium-sized manufacturing enterprises. With the “Green Front Sakai” project leading the way with its excellent ecological
technologies, it is playing a major role in the progression of Osaka Green Bay. Also, as an Eco-Model City, Sakai City is making efforts to take a leadership role in this trend with the realization of “Cool City Sakai”.

Urban Area

Since olden times the urban area has been a developed commercial and business area. Machinery and metalwork industries are located in the northern and southern areas.

Inland Area

Industrial land usage potential in the inland area increased with road development and small and medium-sized business clusters formed in the Kena and Mihara areas. Around the Midosuji subway station, a commercial and business district that covers a large area has begun to form.

Hilly Area

Residential area (Semboku New Town) that was developed in the late 1960’s.
Local commercial and business districts have formed in front of the railway stations.

Urban Area Development

Development in commerce, business administration, culture and residential functions is planned for the urban areas. Maximizing the city’s rich historical and cultural resources, tourism and exchange facilities will be developed and an attractive cityscape will be formed to build a bustling city attracting many domestic and international visitors.

Eco-Model City, Sakai

Forming low co2 energy generation base in waterfront area

The Osaka Bay area is now attracting more companies with cutting-edge and excellent environmental technologies.
Designated as an Eco-Model City by the national government in January 2009, Sakai City has been promoting energy saving with advanced and innovative technologies and has been utilizing various renewable and next generation energy techniques including photovoltaic power and biomass fuel to drastically reduce greenhouse gas emissions. Sakai City is committed to industrial structure conversion from the waterfront area to the entire city to sustain both environmental conservation and economic development.
