The history of ballpoint pen is the history of OHTO!

The history of Ohto started when Nakata Touzaburo, an employee of the Ministry of Finance, invented a special ink, which he thought would be perfect for use in banknotes. After his idea was rejected by the Ministry, Touzaburo decide to establish a company by himself, establishing “Nakata-Ohka-do” Tokyo in 1919 as a manufacturer of ink.

When the United States Army (that had occupied Japan after the World War II) brought ballpoint pens with them, Japanese people were amazed by them and their long-lasting ink system, since ballpoints did not need to be refilled as often as fountain pens. Nakata took note of this, and in 1949 Nakata-Ohka-do released the first ballpoint pen made in Japan, named “AUTO-PENCIL”. It also became the world’s first pencil-shaped ballpoint pen with chrome ball.The company also renamed to “Auto”.
In 1964, the company introduced ground-breaking ballpoint pen”W”using the water-based liquid ink instead of oil-based ink.
In 1974, the company realised that the word “Auto” was too closely associated with cars,
and changed its name to “OHTO”.
Throughout its history, OHTO has been known for introducing innovative technologies in writing instruments.
