A little over one hour from the heart of Tokyo, Gyoda City in Saitama Prefecture is home to lwasaki's modern, fully automated and process integrated Saitama production plant. The 63,000m2 facility contains not only production operations, but also the R & D and testing centres. It is at Saitama that our light sources and Light applied equipment, beginning with an idea and taking shape through design, are given form via world class production operations to be then distributed world wide.

The Honjo Factory is dedicated to assembly and final pre-dispatch inspection of light-applied equipment.

This factory engages in the development, design and manufacture of road traffic information boards; it also boasts an ultramodern printed circuit board packaging facility.
