Not too tricky.  You just add a dead-end tech "Samurai Code" with two 
reqs:  Chivalry (commonly available) and JapaneseRootTech.  Thus Samurai 
Code would only be available to Japanese.  The downsides are:
1. Japanese can build both Knights and Samurai.
2. To build Samurai they have to research an extra tech.
