We are pleased to announce that the funds*1 to which we provide investment-related services completed the capital participation in MINOSHIMA Co., Ltd. (Headquarters: Shibuya, Tokyo, Representative Director: Shigeaki Hayashi, URL: https://www.myisland.co.jp/, hereinafter referred to as “Minoshima”) .

Founded in 1976, Minoshima is a specialized contractor in temporary electrical construction providing power supply systems essential for construction sites. The company has a strong track record of projects across Japan, particularly in eastern Japan, and serves major general contractors, including Japan’s leading “super general contractors,” as its primary clients.

While the aging of skilled workers engaged in temporary electrical construction continues to advance, demand for large-scale construction projects—including condominiums, office buildings, factories, commercial facilities, and public infrastructure—is expected to remain strong. Accordingly, we believe that the need for Minoshima’s efficient and high-quality installation services will continue to grow in the years ahead.

Going forward, we will work alongside Minoshima’s current management team to support the company’s continued growth, with a focus on strengthening its recruitment and development of talent, as well as its sales and management structure. Through these initiatives, we are committed to contributing to the advancement of the construction industry and the enhancement of social infrastructure.

*1 J-STAR Co., Ltd. provides investment-related services to J-STAR No.5-A, LP, etc. directly or via subsidiaries, such as due diligence and recommendation of investment opportunities, and target company management support.
