Yanmar 50th Anniversary movie

Yanmar  realized it 50 years ago:
Large is no substitute for small.

In 1968, it was normal for Japanese people to work using pickaxes and shovels. That's because at the time, construction machinery was large and it could not be used in Japan's small places. "In that case, they should have made small construction equipment," you might think. It's obvious today, but at that time it was a shocking idea.

Come to think of it, Yanmar has brought many things into the world that today seem like obvious ideas. The ability to dig next to a wall and small rear turning radiuses are other examples. We're happy people now consider these things obvious.

We want to focus on customers and invent the next machine that will be considered an obvious idea. In 2018, as we renew that mission, we're marking the 50th anniversary of the Yanmar mini excavator.
