JYS Holdings raised 4.89 billion yen for solar and grid-scale battery projects through green bonds issued on August 29, 2025, the company announced on the same day.
According to the statement, the transaction was arranged by Nomura Securities. The bonds, rated GA1 by Rating and Investment Information, are set to mature on March 10, 2044.
The funds will be used to acquire and develop 19 solar projects across nine prefectures totaling 21.4MW and finance the construction of a 50MW grid-scale BESS project in Naganuma Town, Hokkaido, which JYS Holdings subsidiary Joyo Shoji won in the first long-term decarbonization auction (LTDA). The storage facility is expected to be commissioned in FY2027.
JYS Holdings, primarily an industrial machine parts manufacturer, has been active in renewable energy since 2012. According to its website, it owns 12 solar projects totaling 21.7MW, ranging from a 394kW rooftop system at its factory to a 4.5MW ground-mounted power plant.
The group, through subsidiaries Joyo, Joyo Shoji, and Koyusha, also has three operational 2MW/6.9MWh grid-scale battery storage facilities. Like the extra high-voltage project awarded an LTDA contract, the smaller assets were developed and built by Shirokuma Power. Their construction was subsidized by the Tokyo Metropolitan Government.
