Do you mean to introduce curved blades to Japan, or in general?
The Emishi used curved swords before the Yamato/Wa peoples. The Emishi are credited with the most direct influence in the curving of the once-straight Wa/Yamato swords. This was an early example of what Professor William Wayne Farris calls "Counter-response and symmetry", which can be seen in the importation of Korean horses and later firearms, to name a couple.
It's not inconceivable that the Emishi developed the curved swords independantly of the Chinese in my mind. However, this isn't the proper thread, so I have to stop.
