Message from the representative (Efforts to develop future sales channels, intention to utilize J-GoodTech)
Our company was founded in 1966, and we have spent more than half a century pursuing our own technologies for products including “broach” precision cutting tools, “cast pins,” which are major components of die-casting molds, and “precision rubber molds,” which are used in products in various fields. Today, we have been considered crucial because of the customers who use our products. Although It might sound extreme, it is not an exaggeration to say that the true owners of the company are our customers. We want to continue making products while always taking the perspective of our customers, the owners, to continue meeting their expectations. In addition, it will be an honor if our production activities are able to support a part of the Japanese monozukuri craftsmanship. Even if our role is small, we have a big mission and we will strive to devote ourselves to technology every day. We look forward to your continued guidance and support in the future.
