About us

The possibilities are limitless.


We would like to express our sincere gratitude for your continued support.

Unipoint Co., Ltd. has been in the business of writing tools and cosmetics for about 60 years since its establishment.

Neither our manufacturing technologies are the latest nor complicated. 

However, we have built relationships with the trust of many clients over the years. It is because we have dealt with the needs and issues of our customers.

In recent years, a business succession of small and medium-sized manufacturing companies has become an issue in Japan, but we’ve been taking on new challenges such as human resource development and R&D to become a 100-year company.

We look forward to your continued guidance and cooperation in the future.
