A completely new tool for daily life creating from springs.
"Elasticity changes the way your lifestyle." Based on this concept, we launched our own product brand "lop looop" in 2023.
Utilizing the spring manufacturing know-how cultivated in the automotive industry, we will continue to realize "what it would be like to have something like this" in our daily lives.

We specialize in producing the specialty wire springs.
The origin of the word "Spring" is said to be derived from the muddled form of the verb "To bounce".
A "Spring" refers to an object that temporarily deforms when subjected to force and tends to return to its original shape once the force is removed, thus utilizing its elasticity. Historically, the concept of the spring began with Neanderthals using the elasticity of wood to create traps for capturing animals, which evolved over time to be utilized in the bows and the firearms.
Leonardo da Vinci initiated the mechanics studies, which were followed by the establishment of laws by Galileo, Newton, and Hooke. Today, springs are utilized in a wide range of applications, including automobiles.
Since ancient times, springs have been utilized and developed into more complex forms through the wisdom of our predecessors. We are committed to further advancing and refining the technology of springs.
