Yobanjin

The Yobanjin are tribes of barbarians who live to the north of Rokugan. They look Rokugani and speak a primitive dialect. The Yobanjin were among the original inhabitants of Rokugan, but left when they would not swear fealty to the Kami.

Yobanjin society is usually thought to be quite primitive and backwards. While it is true that they are not as advanced as Rokugan, their true level of development is nowhere near as low as most Rokugani believe.

Trade
The Phoenix village Yobanjin Mura trades with the barbarian tribes, and even though this is technically a breach of Imperial Law the Phoenix use the excuse that the Yobanjin act very much like the Unicorn to continue trade.
