Company information
Our company's history dates back to April 1957, and thanks to your support, we are approaching nearly half a century. Over these 50 years, we have embarked on the development of numerous new products and successfully achieved mass production. We take pride in this accomplishment and the reliability that has been recognized as a result. The 1950s was a time based on Japan's post-war economic recovery, and from the 1960s onward, it was an era that supported rapid economic growth, particularly marked by remarkable developments in industrial products. Our main business, screws (fastening components), is indispensable, and the standard screws we handle alone number in the hundreds of thousands, with the addition of special products bringing the variety close to infinite, and even now, their value remains unchanged. Since then, we have entered the era of electronics and digital industries, and the industrial structure has shifted from mass production and mass sales to a time of small lots and diverse varieties. Currently, the demands of the industrial world are for originality, quality standardization, and speed, with the primary challenge being the reduction of production costs. To overcome this difficult challenge, the first step is the skill enhancement of all employees, united as one company.
