Okada Aiyon History

Okada Aiyon was founded with the launch of OKADA Rock Drill Co. in 1938 by Tatsuo Okada (pen name was Haku-Un) next to the current National Bunraku Theater. However, after that, as the war intensified, the business closed due to war damage. Eventually, Japan was defeated and after the war was a dark period called the black market era. Amid such confusion, in the latter half of 1945 our company started doing business with nothing more than a bag. We used to travel on bicycles around not only Osaka City but also the Amagasaki and Sakai areas.
An iconic event in Japan’s rapid growth was the 1970 World Exposition outside Osaka. Many Okada Aiyon units were used to prepare the exposition site in the Senri Hills. Around this time we imported hydraulic breakers for the first time in Japan. At the time, we never imagined that we would sell American machines in Japan. Even more so, it was inconceivable to us that we would go on to export many hydraulic breakers to the US and other countries.
