Company information
The history of Iris Co., Ltd. began in 1859 (the 6th year of the Ansei era) in Nagasaki's Dejima. A unique foreign trading company, which had customers such as Yukichi Fukuzawa who purchased dictionaries and various domains during the late Edo period, contributed to Japan's modernization and manufacturing by continuously introducing innovative technologies from abroad, eventually developing into the Iris Group. After relocating its headquarters to Hamburg, Germany, in 1898, the Iris Group has continued to operate under the management of the Iris family, spanning five generations of founding members, maintaining an unwavering frontier spirit as a bridge connecting global technology suppliers, primarily focusing on the Asian market. Iris Co., Ltd. remains a key hub of the Iris Group, handling a wide range of technical products and services across various fields, including printing, paper processing, automotive, aerospace, food, rubber processing, X-ray imaging and X-ray CT (Visiconsult and diondo), as well as quality assurance systems and technical materials. The company introduces cutting-edge overseas machine tools and technologies to Japan and specializes in providing project management for corporate users.
