Energy Green

What Energy Green does

Energy Green, operating under the legal entity 株式会社ライズ (Kabushiki Kaisha Rise), is a privately held Japanese green power certificate provider incorporated in Tokyo in 2020 with 2 million yen in stated capital. The company sells グリーン電力証書 (Green Power Certificates) — accreditation instruments that allow enterprise buyers to claim that a portion of their electricity consumption is equivalent to renewable energy generation, supporting RE100 commitments, CDP disclosure, ESG reporting, and carbon offset claims under Japan's Global Warming Countermeasures Act (温対法).

Its core product is a single service category: legally recognized renewable energy equivalence certificates and the associated "ENERGY GREEN" environmental PR mark for use in sustainability communications. The company also operates a downstream retail electricity product under the sub-brand GREENa グリーナでんき, marketed as 100% natural energy and zero CO2 emissions, extending the certificate business into physical electricity supply. The underlying technology is the Japan-issued green power certificate tracking system rather than a proprietary platform; the customer-facing surface is a standard WordPress corporate website used for marketing and inquiry capture.

Energy Green sells exclusively through direct inquiry and contract, with pricing not publicly disclosed. Its customer base is concentrated in Japanese enterprises and organizations pursuing decarbonization and ESG objectives, with no public logos, no named accounts, and no disclosed customer count. The marketing footprint is limited to the corporate website and occasional news releases. The legal entity is closely held with a single listed representative (伊藤/Itō), no disclosed parent company, no external venture or institutional investors, and no subsidiaries.
