In 1919, we established an ink manufacturing company in Tokyo.

Since then, in 1949, we developed Japan’s first ballpoint pen, the “Auto Pencil,”

which was also the world’s first pencil-shaped ballpoint pen using a chrome ball.

Furthermore, in 1964, we introduced the revolutionary “W” ballpoint pen,

which used water-based ink instead of oil-based ink.

OHTO has always been committed to pursuing innovative technologies in writing instruments.
