What are the similarities/differences between Hakoko & Wrestling?

In Wrestling you can fall on your knees and do any kind of moves.
But Hakoko you fall on your knees or if you fall period you lose.
But the same thing is that if you step out the circle your disqualified.
In hakoko only young men could train. But now anyone can train; both males and females. Wrestling is a game enjoyed by the chiefs, back then.
