Steadfast Corporate Policy

Mitsubishi Kakoki Kaisha, Ltd. (MKK) was established in 1935 to meet the need for domestically manufactured chemical machinery at a time of overdependence on imports.

Since then, MKK has grown steadily as an all-round engineering company supplying plant and machinery to a wide spectrum of industrial sectors, including water and atmospheric pollution prevention and other environmental control systems, steel, city gas, petrochemicals, semiconductors, electronics, nuclear power, food and pharmaceuticals. With an eye to the needs of tomorrow, MKK has continued to develop new technologies and expertise. Today, MKK regularly wins lump sum turnkey contracts for plant, facilities and machinery, from planning and design through manufacture, fabrication, installation and construction. As our business has grown, we at MKK have held steadfastly to our corporate policy of supplying high quality products and facilities created with proven technology rooted in the ideals of manufacturing craftsmanship and with uncompromising quality control.
