What Eco Style does

Eco Style Co., Ltd. is a Japanese renewable energy company founded in 2004 and headquartered in Osaka, operating four interconnected business segments: (1) off-site solar power generation development on unused/abandoned agricultural land for corporate off-site PPA customers; (2) on-site solar power generation development for self-consumption at corporate facilities; (3) retail electricity sales under the Eco Style Denki (エコスタイルでんき) brand; and (4) a secondary fund business for solar power plant acquisition and asset management. The company executes the full project lifecycle internally — proprietary land-sourcing tools identify candidate plots, CAD-based systems produce site-specific design drawings, in-house construction teams build the plants, and a dedicated asset management function operates them post-completion.

The company serves two distinct customer sets. The primary segment is large Japanese corporations (e.g., AEON Mall) pursuing RE100 / SBT-aligned decarbonization and ESG mandates through off-site corporate PPA contracts that avoid the need for on-site installation. The secondary segment is landowners holding unused/abandoned agricultural land, who sell or lease their plots to Eco Style for development — converting economically unproductive land into revenue-generating solar assets. A 2022 basic agreement with AEON Mall and the Mizuho Group (Bank, Securities, Lease) covers approximately 1,330 distributed low-voltage solar plants totaling ~115MW supplying ~50 AEON Mall facilities under the "AEON Mall Machi no Hatsudensho" brand.

The company is private, employs 251–500 staff, and operates regional branch offices in Kansai, Chugoku, Kanto, and Kyushu. It raised approximately $1.9M (JPY) from Energy & Environment Investment in March 2018, obtained a specific wholesale supply (Aggregator) license on 2026-01-16, and in April 2026 received an asset management mandate from Q.ENEST Holdings covering 160 solar plants totaling 16MW. A subsidiary, Eco Style Agri (エコスタイルアグリ), addresses agriculture-adjacent land utilization. CEO Kimitaka Kinoshita (木下 公貴) leads the company as Representative Director and President.
