Although not exactly fantasy (although there is magic in the world) I am constantly extolling the virtues of The Amtrak Wars by Patrick Tilley. There's quite a lot of dystopia and postapocalyptia, sex and violence, but there's also tribes belonging to the She-Kargo and D'Troit factions, and a Japanese clan called the Toh-Yota, who have a palace on Aron-Giren (Long Island), along with other clans such as the Toh-Shiba and the Su-Zuki.
The books are a little hard to find, but well worth the read in my opinion. Good action, romance, treachery, all that good stuff.
