ROCKY-ICHIMARU Co., Ltd. (Headquarters: Chikugo City, Fukuoka Prefecture; President and CEO: Hironobu Ichimaru; hereinafter 'ROCKY-ICHIMARU'), boasting a world top-class market share in valves for tire curing presses, has established the holding company 'HainuTech Holdings Inc.' (hereinafter 'HainuTech Holdings') as of April 1, 2026, transitioning to a new group structure.
With the purpose of 'Bundling the evolution of manufacturing to lead social transformation', HainuTech Holdings will use ROCKY-ICHIMARU as its core to integrate the technologies, human resources, and businesses of five manufacturing group companies, each possessing technologies in different domains, to promote the creation of new value through technology succession and co-creation.
Background and Purpose of Establishment
Japanese manufacturing is currently facing a structural issue: the absence of successors. It is reported that approximately 1.27 million companies, accounting for about one-third of all SMEs, have no determined successors, which threatens the potential loss of about 6.5 million jobs and 22 trillion JPY in GDP. Furthermore, the manufacturing industry accounts for about 40% of this, raising concerns that Japan's advanced manufacturing technologies are being lost without being fully utilized.

Against this backdrop, our company was established as a co-creation platform to inherit technologies that are on the verge of being lost and evolve them for the future. We will cross-connect the diverse technology domains possessed by our five group companies, and by collaborating with partners and society, we will expand the possibilities of our technologies.
Through this, we aim to build a co-creation platform that realizes new value creation and consistently demonstrates competitiveness in the global market.
Comments from Hironobu Ichimaru, President and CEO
Every industry in the world is fundamentally supported by countless precise technologies working behind the scenes. However, today, many of the companies that have borne this value stand at a crossroads regarding succession.
HainuTech Holdings was established to inherit these technologies and evolve them into the forms needed for the next era.
The name 'Hainu' (winged dog) is derived from a legendary dog passed down in the Chikugo region of Fukuoka Prefecture, symbolizing the power to support from unseen places and the power to leap towards next possibilities. At its origin lies the spirit of challenge that drove ROCKY-ICHIMARU's growth from scratch to holding a top global market share. Based on this spirit, we will combine the technologies, talent, and expertise of our group companies to co-create new value.
