【SII】FY7 Supplementary Budget: Energy Conservation and Non-Fossil Fuel Conversion Subsidy (Factory/Business Establishment Type)Application assistance service
Subsidy overview
This subsidy program provides significant government support for the cost of equipment investment when small and medium-sized enterprises (SMEs) with factories, stores, and other business premises, as well as large corporations and sole proprietors, introduce energy-saving equipment. This has the advantage of significantly reducing the cost of equipment introduction and leading to lower running costs.
Target projects and frameworks
There are two main types: (I) factory/business site type and (IV) energy demand optimization type. These can be applied for individually or in combination.

Do you have this problem?
- I don't know which application category is best suited for my company.
There are so many categories—advanced technology category, general category, SME investment promotion category, supply chain collaboration category, etc.—that it's hard to decide. - The application forms are enormous, and I'm too busy with my main job to handle them all.
I want to delegate schedule management so I can focus on my core work without being overwhelmed by the sheer volume of paperwork. - I want it to be accepted, but I'm afraid of being rejected due to a mistake.
I want to avoid the risk of being disqualified from the review process due to minor document errors or calculation mistakes.
Benefits of requesting
Managing a massive amount of paperwork and a tight schedule.
By having our firm manage the extensive paperwork, the organization of drawings, and the strict deadlines for mailing, our clients can focus on their core business.
Diagnosis and proposal of the optimal "application framework" and "equipment requirements" for your company.
We offer optimal proposals tailored to your plans and company size, including the "Advanced Framework" and the newly established "Supply Chain Collaboration Framework." We also support you in confirming that the equipment (designated equipment, etc.) meets the requirements.
