Question

Why are most of the oldest companies in the world from Japan?

In: 24

Answer 1

There were no revolutions or civil wars for several centuries, and no foreign invasions for more than a thousand. So a company could continue functioning.

Also, the culture favors old stuff, so company owners try to keep the old name, even if company itself is being completely reorganized.
