Established in 1960, INOUE CORPORATION has continuously expanded to cater to diverse needs. It all started with our commitment to supplying Hitachi, Ltd. with stainless steel products. Our journey has led us to acquire valuable knowledge and skills in the metal materials industry.
Presently, we are recognized as a trusted solution provider for numerous organizations, including our primary client, the Hitachi Group. Through our top-quality materials like stainless steel, titanium, aluminum, nickel alloys, and copper, we strive to resolve a multitude of challenges.
Our expertise encompasses a diverse range of industries such as energy, aerospace, semiconductor, automotive, petroleum refining, petrochemicals, home appliances, and medical devices. We take pride in delivering premium materials and products to meet the demands of these industries. In addition to offering top-quality materials, we work closely with partner companies to provide processing and composite products, ensuring seamless coordination. Collaborative efforts with processing manufacturers within related industries allow us to optimize supply chains and innovate new products, earning us the trust of numerous domestic and international companies.
The past few years have witnessed a sharp increase in the need for engineering disciplines, specifically in areas related to power plants and electrical energy. As the world works towards achieving carbon neutrality, materials that prioritize environmental impact reduction are expected to see a huge rise in popularity. At Inoue, it is our objective to play a proactive role by utilizing our knowledge of special metals and producing processed parts, thus aiding in the progress of industrial civilization and the creation of a sustainable society.
From the time of our establishment, we have made it our mission to constantly meet the demands of our customers. This started with our primary focus on procuring and selling stainless steel and special metals, but as customer needs and the industry evolved, we expanded into new areas. Amid these changes, there is one constant in Inoue's business model - our unwavering dedication to promptly and accurately addressing the needs of our clients. In line with this commitment, we have initiated internal digital transformation (DX) measures, such as implementing a cloud-based order management system, since 2019. These reforms aim to enable us to deliver exceptional solutions at a fast pace, utilizing the full potential of our employees and company resources.
Our greatest pleasure comes from consistently surpassing customer expectations and providing them with products from various countries in the most fitting formats to tackle their difficulties. We understand that Inoue's significance lies in establishing a society where genuine satisfaction abounds by genuinely meeting customer needs, nurturing human resilience, and embracing progress.
Our goal is to provide individuals with the platform to develop their unique areas of expertise and actively contribute within an environment that encourages self-driven pursuit. The remarkable expansion of Inoue can be attributed to our dedicated human resources and their exceptional skills. Each member of our team is a knowledgeable specialist in stainless steel and special metals. It is ultimately our people who generate innovative ideas and drive efficiency. We strive to be a company that harnesses the potential of our employees and nurtures their strengths. This is the guiding principle of Inoue.
Through our prompt response to societal needs, we achieved the top position in the trading industry in 2017. In order to further expand our reach, we have established sales offices in key locations such as Kudamatsu, a renowned industrial city known for Shinkansen manufacturing, in Yamaguchi Prefecture in 2017, followed by the Hitachi Sales Office in Ibaraki Prefecture with a focus on energy plant businesses, in 2019, and the Kobe Sales Office in Hyogo Prefecture in 2022. Our commitment lies in a thorough approach towards local sales expansion, and a determination to enhance our business network by showcasing meticulous distribution functions.
As a specialized trading company, our ultimate objective is to be recognized as a top-tier player in the industry. Inoue shall continue to strive towards this goal by keeping up to date with the latest material trends and offering the most efficient business solutions to our valued customers, leveraging our strong domestic and international network. We extend our sincere gratitude for your unwavering support and generosity.
