To my knowledge nobody does Samurai terrain, villages, castles, temples ect. There are a great many miniature manufactures making figures for this period, Perry miniatures for example. A few companies make resin buildings for this period but the cost of making a village would be prohibitive. Each resin building costs as much or more than one of your whole sets. A japanese version of your villageworks would be a good place to start.

I found some really good free cardstock japanese buildings, and just in time too because I saw this thing on TV that my wife was watching about samurai and I remembered that I had a dozen or so samurai painted so I rummaged out in the garage until I found them and now I just need an opposition force I can do Song Of Blades And Heroes samurai-style.

I also have the Asian Temple, but was less than impressed with it when I went through the instructions. I think the walls and gatehouse might make their way into the buld queue, but not the temple or pagoda.

Where did you find the free buildings?
