Located in Yachiyo, Chiba prefecture (near Tokyo), Toyo-Sasaki Glass was created in 2002 following the merger between the Houseware Division of Toyo Glass and Sasaki Glass, two of Japan's oldest and largest glassware manufacturing companies. The combination of their long-standing traditions, technologies, and extensive sales networks have made TSG the biggest glassware manufacturer in Japan and marked a new chapter in Japan's glassware industry. Toyo-Sasaki make some of the most recognisable and reliable glassware in Japan's foodservice industry.
