A collectible card game, set in a fantasy empire called Rokugan, based loosely upon medieval Japan and Japanese Mythology.

The factions available have changed over the editions, but generally include the 7 Great Clans: Crab, Crane, Dragon, Lion, Phoenix, Scorpion, and Unicorn. Each has specific thematic elements, which are consistent across editions and descendant games.
The Rokugan setting has been changed over the years by participation in the storyline tournaments for the L5R CCG.
The L5R CCG has spun off a number of related games:
As of 2006, only the CCG and Clan War have had storyline tournaments.
In 2009, L5R released its first graphic novel, Death at Koten, which also included exclusive story-themed cards for the CCG.
Also in 2009, L5R released The Imperial Gift the first completely free expansion in CCG history.
