I echo this! Run this adventure twice for two sets of PCs that were new to L5R and they really enjoyed it. One of the PCs was big into Poetry IRL and actually wrote a Haiku; I rewarded him with a Free Raise for his Poetry check and 1 EXP. Also, being a engaging GM really helps out the players too IMO. It made the PCs feel less nerves and more open so they can enjoy the tournament, the murder mystery and the conclusion in a relax manner.
I will proudly admit that I really like L5R but I am fully aware that this setting can come off as intimidating for some players.
