Coo Models has made a couple of Samurai in 1/12 scale, then there's a non armored 1/12 samurai from TWToys. All are higher end figures with cloth outfits.
There are also 1/12 Samurai from Articulated Icons which are all plastic action figures, not on the same level as the ones from Coo Models. Last one that comes to mind is the Marvel Legends Silver Samurai figure, but that's not at all historical and probably not of your interest.
I don't own any except the Silver Samurai which I left in package. I wanted to get at least one Articulated Icons Samurai, but they're now all sold out and overpriced on the secondary market.
