Hoya Corporation (founded nov. 1941 in Tokyo) is a Japanese company that manufactures optical products including photographic filters, lasers, contact lenses, eyeglass lenses using the wavefront technology, tableware and art objects. The headquarters are in 2-7-5 Naka-Ochiai, Shinjuku, Tokyo. It is one of the world's leading manufacturers of photographic filters.
Hoya acquired the camera company Pentax in 2007, for the price of US$1 billion, about 10% more than Pentax was valued at the time. In June 2010 the grandson of the corporation's founder proposed changes to the Board of Directors to prevent what he called such "mistakes" from happening again.
On July 1, 2011, Hoya announced that it agreed to sell its Pentax digital camera business to Ricoh.
