Gates Unitta ASIA Company was established on 14 January 1971 as a joint venture between Nitta Corporation, a Japanese industrial materials company, and Gates Corporation, the American power transmission and fluid power manufacturer. The company was created to combine Nitta's domestic industrial relationships with Gates's belt technology, and it has operated under the Gates Unitta Asia name since its founding. Its registered capital is 380 million yen. From its base in Naniwa-ku, Osaka, the company developed a product line built around the "PowerGrip" trademark, covering timing belts and pulleys in HTD and GT constructions, and later an EV series. Over the decades it added Unitta Mectrol polyurethane belts, Poly Chain GT carbon belts, long-length belts, backlash-free pulleys, micro-V belts and pulleys, stretch-fit belts, auto tensioners and sonic tension meters. The corporate website includes a company history section and a separate product development history section, indicating a long record of incremental product introductions. A key element of the company's identity is its automotive OEM business. Its automotive components division states that its parts have been adopted by all domestic Japanese automobile manufacturers, a position built on the reliability of its timing belt and pulley products. In parallel, its general industrial components division serves a broad set of industries, including semiconductors and LCDs, food and pharmaceuticals, glass, electronic components, home appliances, film and paper machinery, wire drawing, medical machinery, logistics, finance, transport machinery, ultra-low-humidity environments, metals and steel, and automotive applications. As of the end of December 2025 the company employed 250 people. It maintains domestic offices and overseas affiliates, and its shareholders remain Nitta Corporation and Gates Corporation. The company is not listed on a stock exchange; it operates as a private joint venture. Its management team includes President and Representative Director Yew Chong Low and Vice President and Representative Director Toyohiro Hagihara, alongside several directors representing both parent companies and a GUA Japan MD. The company's banking relationships are with Sumitomo Mitsui Banking Corporation and MUFG Bank.
