“The history of ballpoint pen is the history of OHTO”

We celebrated our 100th anniversary in 2019.
We would like to thank you for your support to our products for over a century.

Writing pens and stationery is only a small part of our daily life.
We wish to make our customers happy for that small but important part of life.
Customers’ happiness is our happiness.

In 1949, we commercially introduced oil-based ink ballpoint pen.
To commercialize ballpoint pen was a very hard and challenging job at that time.

In 1964, we introduced new concept in ballpoint pen by pioneering
water-based ink ballpoint pen(present day it is called Roller Pen).

We have developed and served our customers with many products that are common now.
With a limitless spirit and continuous improvement, we will continue to develop products that tend to be common.
