Ishii Machinery – Lean Characteristics
5S, Just-In-Time Production
Ishii Machinery shares a history of monozukuri (Japanese art of making things – manufacturing) with the likes of Toyota and Suzuki Motor. Their origins lie in the manufacturing and sales of loom machines in the 1800s. Their product lines have expanded to equipment and components for the aerospace, automotive and other sectors.
Based in Ashikaga City which is known as the City of 5S where over 200 organizations participate in 5S activities on a daily basis, the company also has been actively involved in the Ashikaga-style 5S Program. 5S is used as the basis for their Just-In-Time production control system in only producing and transporting what is required, at the time it is required, in the quantity it is required. This is their response to the increasing expectations of their customers and society in general.
The plant tour includes a presentation, a site tour and a Q&A session with senior managers.
