[Notice] "Continuing: 50 Long-Standing Companies in Tokyo" has been published.

  • COMPANY

Koyo Seiki Co., Ltd. has been featured in "The 50 Long-Lasting Companies in Tokyo: Part 2." This publication is a sequel to "The 70 Long-Lasting Companies in Tokyo," which was released on April 1, 2020. It was conceived with the belief that "now, amidst the sense of stagnation caused by the COVID-19 pandemic, it is worthwhile to delve deeper into what a company truly is." The featured companies, including ours, are 50 corporations with a history of approximately 60 years or more. The companies range in size from large publicly listed firms to medium and small enterprises, but what they have in common is that their position as companies is firmly rooted in their foundational principles.
