The beginnings of Hashimoto Industry Group can be traced back to 1925 when we were founded as a small factory for processing metal screws that were used in electrical appliances and automobiles. In the course of almost a century since our founding, we have grown into a company that performs a wide variety of processing operations such as metal cutting, forging, resin molding, pipe processing and etc. In particular, we cater to the demands of our customers and have sought to enhance the performance of our products, which includes heat exchangers as well as water control valves and fittings suitable for hot water supply and hot-water heating systems. At the same time, we have built up our company’s development capabilities and expanded the range of technologies in use. In addition to deepening our knowledge of materials such as metals and resins, we have continued to offer products that meet the diverse functional requirements for the hot water supply and hot-water heating systems which draw on the unique attributes of these materials by harnessing our superior technological capabilities. Our company’s proprietary products are all tested and inspected in-house, and our supply system that oversees the entire process leading up to mass production is one of our greatest strengths. We are deeply grateful for the fact that these company’s strengths have been able to bring joy to our customers and offer them a peace of mind for many years.

In our company’s history of almost a century, respecting “minds” is the most important to us. Put differently, the respect for “minds” is the attitude of “being mindful of others” where we put our customers before ourselves, a principle that has motivated us to always take the tasks before us seriously. The superior technology and development capabilities of Hashimoto Industry Group today are the fruits of this labor, and we believe that these achievements are only possible because of the relationship and mutual trust between our customers and us. Our company’s mission is to enhance productivity by making full use of information technology and continue to evolve as we improve on our strengths developed in the past, while preserving our commitment to the “relationship and mutual trust” and the respect for “minds.”

We will stride into the future with pride as a development engineering company which has the passion to take on challenging operations and the innovation to disrupt existing conventions.
