How did the buddhist religion reach japan?

It came from the trade routes , my reason being is because along the trade routes many things were traded , not only food salt or gold but religion was too.

It impacted Japan so much that most people Today would say that Japan created it . 

Japan actually use to be confused , meaning that they had no religion.

I really hope that this helps you out a lot. 

Perspective is important because it enabled the 3 dimensional world to be translated into the 2d world of the picture plane. this had an immediate impact on the representation of reality in art and design.
