What if the Tokugawas opted for a Japan of trade instead of isolation?

The Shogunate would've been brought down sooner.

The entire reason they shut down foreign trade was because their former enemies, who were completely removed from positions of power in the government, instead sought power by trade.

They could potentially end up like China.
On the other hand should they be able to
do it correctly it's not hard to imagine them
becoming extremely wealthy as they were
abundant in some resources valuable to
European merchants and the like.

Tokugawa Ieyasu was pretty much a promoter of exploration and openness and even commissioned a few European style ships.

However, his grandson or thereabouts had a conversation with a Spanish priest who showed him a map of all their colonies so he chimped out and banned Christianity and open trade except for the Dutch.

They might not end up industrialized by the late 19th century.
