【Management Support Professionals × Renewable Energy Technology Professionals】SAKURA United Solution Co., Ltd. Concludes Business Matching Agreement with San-ei Sangyo Co., Ltd.

SAKURA United Solution Co., Ltd. (Shibuya Office: Shibuya-ku, Tokyo; Head Office: Minami-ku, Saitama City, Saitama Prefecture; Representative Director: Issei Inoue; hereinafter "SAKURA") has concluded a basic business matching agreement with San-ei Sangyo Co., Ltd. (Head Office: Kanonji City, Kagawa Prefecture; Representative Director: Eiji Nitta; hereinafter "San-ei Sangyo"), which specializes in renewable energy construction technology, on April 14, 2026.

Through this partnership, SAKURA's nationwide network of professionals, experts, and financial institutions will be integrated with San-ei Sangyo's advanced construction technology, providing strong support to SMEs in addressing the management challenges of "soaring electricity costs" and "responding to decarbonization" from both financial and technical aspects.

Background of the Partnership: Why a "Professional Group" is Venturing into Renewable Energy Support

Currently, Japanese SMEs are at a major turning point, facing waves of legal revisions such as the "mandatory solar panel installation target in 2026 (※1)" and continuously rising energy costs. However, the introduction of renewable energy requires not only advanced technical judgment but also specialized "back-office operations" such as subsidy applications, securing financing, and tax processing, which have been major barriers to adoption.

As a "partner for SME management," SAKURA has supported the financial soundness of many SMEs. By teaming up with San-ei Sangyo, a technology professional, we have built a system to convert "technology (San-ei Sangyo)" into "corporate profits and asset value (SAKURA)."

※1 The content and scope of the system vary depending on the local government and application.

Turning the "Energy Isolation" Crisis into an Opportunity for Growth. The Challenge of SMEs to Connect a Sustainable Japan to the Next Generation.

The energy crisis, stemming from geopolitical risks, is a serious social issue that fundamentally shakes the management of SMEs in Japan, a country with low resource self-sufficiency. Each time energy prices soar, entrepreneurs, who are the backbone of the economy, suffer immense damage. We are convinced that solving this structural challenge of "energy dependence" in Japan is now a national imperative that transcends the profits of a single company.

Japan is said to be a resource-poor country. However, the energy of sunlight shines equally on all SMEs in this country and around the world. Maximizing the use of this "equal blessing" and paving the way for energy self-sufficiency will be the "foundation" for building a resilient management base that is not affected by external factors.

For us SMEs to work together to solve the energy problem means enhancing the resilience of the Japanese economy and becoming a bearer of a decentralized energy society. Building this foundation is our generation's earnest responsibility to hand over a sustainable society free from energy anxiety to the children of the future.

We declare that companies with completely different business objectives will join forces, place the solution of energy issues at the core of their management, and with ingenuity and passion, become pioneers in opening up the future of Japan for the next generation.

Overview of "All-in-One Stop Support" through this Partnership

Both companies will clearly divide their strengths and provide consistent support from introduction consideration to operation.

● Role of San-ei Sangyo Co., Ltd. (Hardware/Technical aspects):

○ Comprehensive technical support, including proposals, installation, construction, and maintenance of solar power generation facilities and storage batteries.

● Role of SAKURA United Solution (Software/Management aspects):

○ Sales and consulting through a network of professionals such as tax accountants, social insurance labor consultants, administrative scriveners, and lawyers.

○ Support for utilizing subsidies and preferential tax systems (e.g., immediate depreciation), and coordination for financing with financial institutions.

This enables managers to focus on their core business while simultaneously achieving "electricity cost reduction" and "ESG management (Environment, Social, Governance)" with minimal burden.

Comment from Representative Director Issei Inoue

"This partnership with San-ei Sangyo is not merely about introducing equipment. It aims to view renewable energy adoption as a 'proactive financial strategy,' maximize the use of tax incentives and subsidies to improve corporate cash flow, and build a strong management foundation for future generations. By combining the expertise of technology professionals and management professionals, we will accelerate the decarbonization of the regional economy in an effective manner."
