1905

Established

Opened the Hitachi Mine

Company founder Kuhara Fusanosuke opened the Hitachi Mine, launching the resources development and smelting and refining businesses. From the very beginning of its operation, Mr. Kuhara actively promoted mechanization and modernization to improve productivity. The Hitachi Mine pioneered the custom smelter, using its full-fledged facilities to process not only ores from its home mine, but also those purchased from other firms.

Built the Hitachi Giant Stack

The rapid growth of the Hitachi Mine’s business led to severe smoke pollution in its 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.

1916

Launched operations 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. It was one of the largest such plants in Japan. Even to this day, it remains a key location within the JX Nippon Mining & Metals Group, as a leading-edge smelter boasting worldclass technological capabilities and production capacity.
