Founding of Miura Seisakusho

Father of company founder Tamotsu Miura foresaw the potential demand for agricultural machinery for use in an area where manual labor was the norm. He founded the Miura Seisakusho in Matsuyama, Ehime, and began to manufacture and sell machines for polishing barley and rice.

As the economy expanded, MIURA foresaw that demand for boilers as a fundamental piece of machinery would grow and took the step of making the company's own model. Boilers with a multiplicity of uses had varied applications, and they became a driving force behind the development of MIURA.
