To be your best business partner
Manufacturing companies face various issues such as Iot、AI、SDGs、Sustainable, decarbonize. Raising productivity, high quality, and a defect rate as close to zero as possible have been told as Japan''''s basic stance on manufacturing. Although, I think that excessive kaizen has made companies rigid and has become a constitution that cannot think flexibly. CASTEM aims to be a company that thoroughly continues to make attempts to attract new needs that have never been seen before. I would like to review once again the very old stereotype like “this shape and this material are only for this application” and reincarnate it with a completely new form and material with current technology. And we want to walk with pride as a partner, not as a subcontractor to our customers. We will be the brand-new manufacturing company that freely repeats changes and combinations like an amoeba while possessing a basic pyramid structure, and the whole is harmonize. We will draw a future forecast that everyone will be excited about.

Creating
CASTEM Group''''s passion for manufacturing has driven us to work for human resources development. Setting up a division working on paper airplanes. is its prime example.
A single piece of paper turns into an airplane flying over the great blue sky, and a small technical effort makes different trails.
Such a small experiences leads children to future efficient engineers. From a small factory to a leading developer of technology, our evolution never ends.
