The headquarter of Ebara Corporation is located near Haneda Airport. While the place we visited was the Fujisawa District of Ebara Corporation. Fujisawa Plant was established in 1965. It has already acquired some certifications like ISO 900, ISO 14001. There are several factories of Ebara, like the headquarter near Haneda, the factories at Fujisawa, Sodegaura, and Futtsu. Fujisawa plant has an area of 360.436 m2 with 2500 employees. The Fujisawa District was established for mass production of small pumps, as well as refrigerating machines, fans, blowers, and boiler systems. Later it also produced engineering pumps for heavy-duty use, vacuum systems for the semiconductor industry, and equipment for semiconductor fabrication.

At first, we heard some explanations from the staffs of Ebara Corporation and also saw some demo of a small model about how their pumping system worked. It was also said that the products of Ebara Corporation were used in some famous places like Merlion Singapore, Water Supply Museum in Taipei, Taiwan. After the presentation we had a tour of Fujisawa factory.

The places we visited were standard pumps assembly shop, industrial pumps machine shop, industrial pumps assembly shop, and precision machinery shop. In those machinery shops we could see how the workers worked and also how the systems of many processes in the factory worked. Every product of the factory was examined so that they can guarantee the quality of the products. The products that did not satisfy the specifications were put out in a special place and marked at their unsatisfying parts. We also looked at the system test clean room where the workers should all wear sterile clothes.
