To make the world unique and not just another generic fantasy setting, I want to include some "asian visuals" to make things a bit different. Like the Night Elves in Warcraft combine Japanese and Scandinavian architecture.

Here's some stuff I already have:
Bamboo
Straw Hats
Turtles
Rakshasa (though still the D&D type)
Oni
Naga
Hengeyoukai (natural lycanthropes from the spiritworld)
Lamellar armor
Naginata (as glaives)

More ideas are welcome.
