I would agree, but with the caveat: "if you are using Rokugan as the primary setting of your campaign." If, instead, Rokugan is the far-off land where travelling Monks and Samurai come to your medieval European pastiche setting, then Rokugani is an alternate language to learn or know. AD&D's Oriental Adventure, while obviously not including Rokugan/Rokugani, seemed to be better about threading the needle of 'use this material however you want.'
