OHTO's history of innovation dates back to 1929. That is when the company was established in Tokyo and began to manufacture high quality dyes and ink. In 1949 they manufactured the world's first pencil-shaped ballpoint pen with chrome ball. This pen was also the first MADE IN JAPAN ballpoint pen. We can also thank them for other present-day standards like the Roller Pen, which they invented to bring the experience of writing with a ballpoint pen closer to a fountain pen. They also invented ceramic balls in pens and were the first to add rubber grips in pens. OHTO also produces the ink refills for the Midori Brass pens.
