Nippon Sheet Glass Co., Ltd. (日本板硝子株式会社, Nihon Ita-Garasu Kabushiki-gaisha) is a Japanese glass manufacturing company. In 2006, it acquired Pilkington of the United Kingdom. This makes NSG/Pilkington one of the four largest glass companies in the world alongside another Japanese company Asahi Glass, Saint-Gobain, and Guardian Industries.

The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 stock index.[3]


The company was established in November 1918 as America Japan Sheet Glass Co., Ltd. with its head office in Osaka, after it obtained technology from Libbey Owens Ford Glass Co. of the United States to produce flat glass using the Colburn process. The company changed its name to the Nippon Sheet Glass Co., Ltd. in January 1931. It expanded operations across Japan post World War II, and in October 1970, acquired Nippon Safety Glass Co., Ltd. In April 1999, the company merged with Nippon Glass Fiber Co., Ltd. and Micro Optics Co., Ltd. In April 2001, the company acquired Nippon Muki Co., Ltd. and in July 2004, moved the registered head office from Osaka to Minato Ward in Tokyo.[4]


In 1986, Pilkington bought Libbey Owens Ford. Following an agreed acquisition of 20% of Pilkington of the United Kingdom in 2001, in 2006, NSG purchased the residual 80% of shares.


Founded in 1918, NSG acquired the leading UK-based glass manufacturer Pilkington plc in June 2006. Today, the company has combined sales of approximately JPY 600 billion, with manufacturing operations in 29 countries and sales in 130 countries, employing some 28,500 people worldwide.

The Group's Flat Glass businesses, encompassing Building Products and Automotive Products, account for 90 per cent of annual sales, with the balance being in Specialty Glass. The Specialty Glass business covers a number of niche markets, the most important of which are in displays and optical products for printers and copiers.

Geographically, 42 per cent of the Group's sales are in Europe, 28 per cent in Japan and 13 per cent in North America, with the rest primarily in South America, Southeast Asia and China. [5]
