This is a cut and paste/recolor based on Fabrizio Prudenziati's 90mm/1:18 scale (naked) Greek Hoplite into a Japanese Ashigaru spearman in service to Takayama Shigetomo around 1582, using modular parts from his other French soldiers and armor from Niku Mansei.

Edit: 21 December 2018
Added a file with additional sashimonos, helmets, armor and bow for many more build variations.
