The city of Saitama, a major bedroom community of Tokyo and a host of venues for basketball and soccer games during the 2020 Olympics, attracts many companies with leading technology that Japan can be proud to showcase to the world.

Adjacent to one of the world's largest cities, Saitama enjoys the benefits of being close to a huge market. Because many large manufacturers, which are their customers, are located nearby, it is home to many small companies using their cutting-edge technology to manufacture products.

Many of Saitama's companies make components and materials, rather than end products, meaning that most of these companies do not enjoy as much name recognition as they may deserve. However, their components and materials go into many products that support people's daily lives and their excellent craftsmanship techniques can be a major part of the Cool Japan campaign promoting tourism and the unique culture of Japan.
