During the 1960s, Japan was in the midst of a period of high economic miracle. The Tokyo Olympics triggered the government’s policy on high economic growth and the implementation of large-scale infrastructure development. Hence, our company was founded in 1964 when the first Tokyo Olympic Games were held in Tokyo.
Started from post-installed anchors which were used when attaching objects to concrete, we develop, manufacture and sell construction related products such as drill bits and fasteners. Today, we continue expanding our business widely with the keywords of “safety, security, and environment”. Our new business includes; seismic retrofitting, solar related construction management, manufacturing and sales of alcohol detectors and FRP sheets.
Fastening
Our main business, the fastening business,
develops, manufactures and sells construction materials.
It develops original installation methods and manage on-site construction by utilizing the know-how accumulated over many years.
We develop, manufacture and sell construction and engineering related materials such as construction anchors.
Fastening Related
In addition to planning and development, raw material procurement, manufacturing and sales of construction materials such as drills and fasteners, we also have other construction tools and anchor tensile testing machines. We aim to create a consistent quality and offer the “total fastening system”.
Among them is “All Anchor”, which is said to be synonymous with our company. It is our most well-known product that is sold and used all over Japan for more than 50 years.
Engineering Related
Various structures created during the period of high economic miracle in 1960s or what we call the “construction rush” has been deteriorating over time and has reduced durability against natural disasters such as earthquakes, etc.. At our company, we are developing and managing installation methods to protect various structures such as schools, hospitals, highways, railways and piers by applying fastening technology such as post- installed anchors and utilizing them for seismic retrofitting work.
