Start of operation at the Hitachi Mine

Founder Fusanosuke Kuhara started operation at the Hitachi Mine, launching the Mineral resources development business and the smelting and refining business. From the beginning, Kuhara sought to boost productivity by actively embracing mechanization and modernization. The Hitachi Mine was a pioneer in development as a full-fledged custom smelter that processed not only its own ores, but also ores purchased from other companies.

Construction of the Hitachi Giant Stack

The rapid growth of the Hitachi Mine's business led to a severe smoke pollution problem in the surrounding area. To deal with the pollution, the Company built what was then the world's tallest stack at 155.7 meters. It began operation in March of the following year.

Start of operation at the Saganoseki Smelter & Refinery

In order to further expand the mining, smelting and refining segments fundamental to the Company's diversified business, the Saganoseki Smelter & Refinery was built in Oita Prefecture as one of the largest such plants in Japan. It remains even to this day an important center of the JX Nippon Mining & Metals Group, as a leadingedge smelter boasting the world's top levels of technology and production capacity.

Kurami Works launched

With the startup of the Kurami Works (Kanagawa Prefecture), the Company made a strong entry into the metal fabrication business. Introducing the latest rolling mills, it produced phosphor bronze and other rolled copper products. By answering the needs of complex markets for flexible manufacturing of diverse products in small lots and production-to-order, while meeting demands for advanced product technology, the Company established a solid position in the metal fabrication field.

Isohara Works launched

The Company got into the electronic materials business in time for the rise of the electronics industry in the 1980s, making sputtering targets for semiconductors and transparent conductive films for liquid crystal displays, as well as materials for compound semiconductors. By establishing the Isohara Works (Ibaraki Prefecture) as a new main manufacturing center,
the Company expanded into development and manufacturing of copper foil and various electronics materials.
