HIRAYAMA HOLDINGS Co.,Ltd. has expanded its business scope through M&A, building on its insourcing and staffing services. It has announced a policy to change its corporate name to ケディックスホールディングス in January 2027.
HIRAYAMA HOLDINGS Co.,Ltd. operates in Japan and overseas, centered on its core insourcing and staffing services, with strengths in services that work with on-site improvement consulting to enhance productivity. It plans to expand its business scope through M&A, and is scheduled to change its corporate name to ケディックスホールディングス in January 2027.
The company began providing contracted on-site manufacturing services in 1989 and changed its organisational structure to 平山 in 1992. It was listed on the Tokyo Stock Exchange's JASDAQ market in 2015, then moved to a holding company structure in 2017 to pursue its M&A strategy. Following the 2022 market-segment restructuring, it moved to the Standard Market and is scheduled to change its corporate name in January 2027.
As of the end of June 2026, the group comprised 11 consolidated subsidiaries and 10,697 employees, including 7,551 in insourcing and staffing, 606 in technical staffing, 2,268 in overseas operations and 175 in other businesses. It has established a structure that also encompasses overseas operations and consulting services.
To strengthen its operating base, the group successively absorbed Fun to Fun in December 2025 and 平和鉄工所 in July 2026. It also plans to absorb トップエンジニアリング in January 2027, advancing a reorganisation of the group structure.
