Juuin Province
From Heroes Of Rokugan
This province straddles a mountain range and forms the militantly guarded border against the Crane lands. East Mountain Village and West Mountain Village are found in the province, and the mountains are famous for their jade mines. Much of the jade the Crab produce comes from this province. The mountains are riddled with caves, and the Eastern side is purged yearly of the unpleasant creatures who dwell there.
