Non-residential subsidies

[SII] Energy Conservation Investment Promotion Support Project

Updated: July 2025, 12


This is a subsidy system for businesses that reduce energy consumption by introducing highly efficient air conditioning, lighting, production equipment, etc. Subsidies are provided for investments with a high energy-saving effect, making it possible to significantly reduce the cost of introducing equipment.

Our company will have administrative scriveners handle all of this subsidy application procedures on your behalf.

* If a subsidy application is handled by someone other than an administrative scrivener, it may be in violation of the law.

  • We can handle all the complicated paperwork and communication with SII.
  • This reduces the initial cost burden of capital investment, directly strengthening the company's competitiveness.
  • You can rest assured that we will handle your request with professional staff who have a proven track record of receiving numerous subsidies.

By utilizing subsidies to invest in energy conservation, you can achieve both cost reduction and sustainable management.
