Corporate Philosophy
– Management philosophy –
“YSM will continue to illuminate the future of the people whose lives we touch, while giving tangible shape to those things they live with and enjoy every day.”
We convert people’s ideas and elements of their imagination, not yet expressed as drawings, into pleasing shapes. Conceiving of new things and manufacturing them are just some of the steps in our creative process. We invest our products with such intangibles as empathy and excitement. We think this makes us a company worthy of being chosen again and again by customers and cooperating companies alike. We hope to light the way to the future in our quest to illuminate the world.









Custom Lighting
We can create lighting from an idea a customer has originated, that has not yet been expressed as drawings.
Our experienced staff will understand your ideas, help you with the design and make the necessary drawings.
We use our 20 years of know-how and our own machines to deliver finished products to you that started with simple statements of your basic product needs.
Over the past 20 years, we have delivered innovative products to major construction and railway companies.
