My latest terrain piece for my 40mm samurai collection: The bamboo wall is made from a strip of place mat, the path and zen rock garden are sculpted from green stuff, the flowers are hibiscus shrubs by JTT scenery, the base is a 120mm round by Proxie Models, and the woman is by Steve Barber Models.
FYI, if you like Japanese minis gaming, I recommend the Fuedal Japanese Miniatures group over on Facebook. I will be posting much of my Japanese stuff there, too -- the posts here and there will be a bit the same, just in case you prefer one-stop-browsing :)
I have one more 120mm base left, so I think I will do a rocky creek with plenty of ferns. Might be a while, I still have a bunch of new converted Japanese figures to paint!
