"Founded on a spirit of freedom and autonomy, a city where anyone can be happy, healthy, and play an active role"

Vision for 2030

As represented by the Egoshu of Japan's medieval period, the people of Sakai believe in governing themselves, maintaining peace, and using international exchange to build prosperity. This spirit of freedom and autonomy continues to this day.

Utilizing this spirit, enthusiastic business operators are actively engaging in energy and the environment, healthcare, and other growth industries and new fields, and are creating new businesses.

Thus, vibrant local industries are creating new employment and business opportunities, and everyone is playing an active role. Furthermore, coexistence with natural environment, and enhanced childcare and school environments, parents can give birth and raise their children with confidence and reassurance. At the same time, the city's enhanced health and medical system is a comfort to older people and another reason why so many people settle here.

Sakai's fascinating historical and cultural resources also draw in many people from both within and outside Japan. And with the city's keenly autonomous residents actively engaged in community development efforts, Sakai is bustling and prosperous.

Sakai is a sustainably developing city: its bustle and prosperity attract people and business, which leads to further industry development.

(ZEH) use

Source: Definition of ZEH and future measures proposed by the ZEH Roadmap Examination Committee (December 2015, Energy Efficiency and Conservation Division, Agency for Natural Resources and Energy, Ministry of Economy, Trade and Industry)

ZEH is a dwelling that, while maintaining a comfortable indoor environment, achieves net annual energy consumption of nearly zero (or less), made possible by generating energy via solar power, etc., and by maximum efforts to conserve energy through home insulation improvements and high-efficiency equipment.

ZEH addition in Sakai

Fixed amount: 100,000 yen

Initial: 70 houses

Smart house conversion 270,000 yen + ZEH addition 100,000 yen = Maximum 370,000 yen
