Kubota Corporation was founded in 1890 in Osaka, Japan.

The initial specialization of the company was the production of cast-iron pipes for water pipes.

Then, in 1920, the company launched the production of internal combustion engines, which found their main application in agriculture. Also, more powerful diesel engines were intended for agricultural machines, the production of which was mastered in the 30s.

Gradually, the production of engines became the main specialization of the company; Kubota Corporation engines are also used in Wilson generators. In 1972, the first foreign representative office of the company was opened in Indonesia. Since then, Kubota Corporation products are sold in more than 130 countries.

Now Kubota Corporation is an international leader in three product groups: internal combustion (incl. marine) engines, industrial products, building materials.

In 1987, the release of the 10 millionth engine was recorded, and already in 2003 this number was doubled.
