As I'm doing 6mm Samurai they need some buildings. But finding them terrain is not so easy. All the traditional suppliers do the standard European and ACW ranges, but 6mm Japanese? No.
So I've done some digging and found Mura Miniatures http://www.muraminiatures.com/home.html. Which I really like. So some of these are coming home to Daddy.
There is also a Canadian store (http://www.udisco.com) that sells model castles, but I don't know how much they cost. I'm guessing 'not cheap'.
Irregular do a Japanese castle for £12 so that's also an option. They also do Chinese buildings that could do. Or maybe not.
Paper Terrain do paper / card templates that could also do. http://www.paperterrain.com/
Oshiro (http://www.oshiromodelterrain.co.uk) do some really nice stuff - but 15mm. Damn!
So - looking at the options, it looks like Mura Miniatures is the winner.
