Yachiyo Engineering Joins the Global Impact Investing Network (GIIN)

In May 2025, Yachiyo Engineering Co., Ltd., headquartered in Taito, Tokyo, announced its membership in the Global Impact Investing Network (GIIN). GIIN is recognized as the largest network dedicated to impact investing globally, where various stakeholders—investors, financial institutions, businesses, and nonprofit organizations—come together to resolve social and environmental issues while ensuring financial returns.

The company's commitment to solving challenges in infrastructure development and environmental and social sectors spans many years. By joining GIIN, Yachiyo Engineering aims to enhance its practices in Impact Measurement and Management (IMM), adhering to global standards, thereby promoting responsible investment and business support both domestically and internationally.

What makes this membership particularly noteworthy is that it is a rare instance of a Japanese business joining GIIN, making Yachiyo Engineering the first development consulting firm in the country to do so, outside of the financial sector. This move brings fresh perspectives and opportunities for the practical implementation of impact investing.

Through its activities with GIIN, Yachiyo Engineering looks forward to collaborating with partners worldwide to maximize social impacts that contribute to a better future. This involvement aligns perfectly with the company's mission to integrate sustainable practices into its strategies, reinforcing its dedication to addressing pressing global challenges.
