10mm figures, mainly Pendraken, but some Irregular and AIM, and a very few Magister Militum. The houses are 6mm Mura, the castle and pond scratchbuilt, and I bought the torii out of a battered cardboard box of odds and ends in a small shop in Kyoto, I'm afraid (though I think it's from a Japanese model railway terrain maker).
The rules were my own, Ten More Sons!, which I am happy to send to anyone interested. I used to do Japanese in 15mm back in the 1990s, but since adopting a more international lifestyle I've reduced scale; as it is, storage is still on the edge of crisis most of the time.
