It built vehicles from about 1926 until 1962 when a subsidiary of Nissan, called Nissan Machinery (Nissan Koki Co., Ltd. 日産工機), assumed operations as the company had become a member of the Nissan Group keiretsu. The word kurogane (くろがね or 鉄) is an old term for iron, and one of the kanji used in Mr. Makita's first name. Remnants of the company were called Nissan Machinery (Nissan Koki) until 1985, and operated as a separate entity within Nissan Techno (日産テクノ) until 2006, building and developing all of Nissan's current engines.
