UAM Philippines, Inc. was established on March 03, 2005 on West Service Road, Cupang, Muntinlupa City. Ninety Nine Percent (99%) of its shares is owned by Union Auto parts Manufacturing Co. Ltd., the first company that produces rims, spokes, nipple for motorcycle and plating service industry in Thailand since 1982. Both companies are supported by its ultimate mother company Okaya & Co. Ltd., one of the largest trading corporations in the global network since 1669.
The first mass production was in July 2005 and due to its immense expansion, UAM Philippines, Inc. decided to increase its capital through the support of its mother companies. By July 23, 2007, it transferred to the First Philippine Industrial Park to manufacture spokes and nipples for Japanese motorcycle makers. To achieve higher revenues, UAM Philippines Inc. was engaged in the importation of raw materials from Thailand for motorcycle wheels beginning May 2011 that merely increased the company's gross profit.
A trading division and Makati Branch were established in July 2017 to expand its ultimate mother company Okaya & Co., Ltd.’s business activity in the Philippines.
Currently, UAM Philippines, Inc. is supplying assembled rims to the four major Japanese and other foreign motorcycle manufacturers in the Philippines, namely Honda Philippines, Inc., which is the major customer, Yamaha Motor Philippines, Inc., Suzuki Philippines, Inc., Kawasaki Motors (Phils.) Corporation, and Kymco Philippines, Inc.. UAM Philippines, Inc. believes in valuing customers through continuous improvement in order to provide high-quality products and services.
