Overview

Ishikawajima Iwakuni Seisakusho, Ltd. (株式会社石川島岩国製作所) was a Japanese manufacturing company located in Iwakuni, Yamaguchi Prefecture, and part of the IHI (Ishikawajima-Harima Heavy Industries) corporate group. Its name combines the historic Ishikawajima brand — the founding name of the IHI conglomerate — with Iwakuni, the city where its works were based. The company operated as a manufacturing entity within the IHI Group, producing industrial machinery and related equipment. The company's own website records that in July 2007 (Heisei 19), Ishikawajima Iwakuni Seisakusho merged with Ishikawajima Industrial Machinery Co., Ltd. (石川島産業機械株式会社) to form IHI Machinery System Co., Ltd. (株式会社IHI機械システム). Following that merger, the old website was renewed and redirected visitors to the new IHI Machinery System homepage. The copyright notice on the archived site reads "2007 Ishikawajima Iwakuni Seisakusho Co., Ltd." As a result of the 2007 merger, Ishikawajima Iwakuni Seisakusho ceased to exist as a separate legal entity and brand. Its operations were absorbed into IHI Machinery System, which continues as part of the IHI Group. The company is therefore best understood as a historical subsidiary brand within IHI's machinery and industrial systems business, rather than an independent active company.

History

Ishikawajima Iwakuni Seisakusho, Ltd. was a Japanese manufacturing company based in Iwakuni, Yamaguchi Prefecture, and formed part of the IHI Group. The Ishikawajima name traces back to the origins of IHI (Ishikawajima-Harima Heavy Industries), one of Japan's major heavy-industry conglomerates, while the Iwakuni designation refers to the city where the company's works were located. The company operated as a manufacturing entity within the IHI Group, producing industrial machinery and related equipment. Its official website carried the copyright notice "2007 Ishikawajima Iwakuni Seisakusho Co., Ltd." The decisive turning point in the company's history came in July 2007 (Heisei 19), when Ishikawajima Iwakuni Seisakusho merged with Ishikawajima Industrial Machinery Co., Ltd. (石川島産業機械株式会社) to create IHI Machinery System Co., Ltd. (株式会社IHI機械システム). As stated on the company's own website, the merger led to the renewal of the homepage, with visitors redirected to the new IHI Machinery System site. Following the merger, Ishikawajima Iwakuni Seisakusho ceased to exist as a separate legal entity and brand. Its operations were integrated into IHI Machinery System, which continues as part of the IHI Group. The company is thus a historical subsidiary brand within IHI's machinery and industrial systems business.
