OST will celebrate its 22nd anniversary on May 8, 2025.
We owe this milestone to our customers, business partners, and above all, to all our employees who continue to work hard every day.
We would like to express our sincere gratitude.

Looking back, the company started with just a few people at the time of its founding, but now has more than 200 employees and has grown into a company that is loved by many customers.

At the April entrance ceremony, 17 people joined the company (including 6 foreign nationals), and the number of foreign members has increased to 23 from 11 countries.

We held a 22nd anniversary ceremony on May 7, and a new employee welcome party on May 9 as an after-party event.

We hope to continue to be a company that can open the door to the future with open ideas and solve social problems.
