OHTO was established in Tokyo, Japan in 1929 and began manufacturing high quality dyes & inks. The company has a long history of ink manufacturing as the founder of OHTO, Nakata Tozaburo, worked for the ministry of finance and invented a special ink for Japanese banknotes. Mr. Nakata went on to develop the first ballpoint pen manufactured in Japan in 1949. After the success of their 'Auto-Sharp' ballpoint pen, OHTO went on to design and manufacture the world's first rollerball pen in 1964.
The OHTO range now includes the original ballpoint and rollerball pens, as well as a range of writing instruments that suit your every need, from mechanical pencils to graphic liner pens, plus ceramic rollerballs, fountain pens and multi-function pens. OHTO continue to expand on their almost 100-year history of ink & writing instrument production by designing and developing new innovative products.
