About Sanjo Seiki

Business credo

  • “ Sell ideas” means that the Company should make products that are different from competitors’ and each employee should generate value worth selling through their work. Employees are given an infinite authority for planning, including planning for products and work improvement. They are encouraged to demonstrate creativity and ingenuity and make suggestions. At the same time, they are required to make constant efforts to gain insights, while avoiding inertia and lack of ideas.
  • “Stay away from vanity” means that the Company and employees should keep a low profile and act in a down-to-earth manner. In terms of business management, it means to practice “reasonable things”. While striving to improve profitability by daily cost reduction and increase internal reserves, the Company proactively reinvests in new product development, quality and productivity improvement, human resource training and environmental improvement, which are necessary for long-term development.
  • “Connect directly with customers” refers to the Company’s attitude to directly listen to customer’s opinions and requests and reflect them on product development and improvement and services, thereby responding to customer needs.
