In Japan’s Sengoku period — the Age of Warring States — power was measured not only by swords and soldiers, but by the flow of goods, ideas, and gold.
Among the warlords, Oda Nobunaga stood out as a true reformer. While others built walls, Nobunaga opened roads.
The Story: Breaking the Barriers
During the 16th century, Japan was divided into small domains, each with its own checkpoints called “sekisho”.
These checkpoints collected tolls — a kind of customs tax — that slowed down travel and trade. Farmers, merchants, and travelers all had to pay when crossing regional borders.
It was a world where “movement” was expensive.
Then came Nobunaga.
He boldly abolished the checkpoints in his territory, declaring that people should move freely to buy, sell, and learn.
By removing these barriers, he connected regions, encouraged markets, and strengthened local economies.
In short, he created a network — long before the internet — where information, goods, and opportunity flowed without interruption.
The Lesson: Flow Creates Power
Modern global trade follows the same rule.
When tariffs, regulations, or logistics barriers become too heavy, business slows down.
But when borders open — even slightly — innovation and collaboration rise.
Trade is not just about profit; it’s about connection.
Nobunaga understood something timeless:
“Control the flow, and you control the future.”
He didn’t just trade rice or weapons — he traded energy between people and places.
That same principle drives today’s digital economy, where speed, trust, and open systems create new markets every day.
What We Can Learn
- Reduce friction.
Whether in business or communication, remove unnecessary barriers that block flow. - Encourage exchange.
Share knowledge, collaborate, and trade ideas — not just products. - Build systems, not walls.
Like Nobunaga’s open roads, create networks that make cooperation natural and profitable.
