Throne of Blood - Production

Production

The castle exteriors were built and shot high up on Mt. Fuji. The castle courtyard was constructed at Toho's Tamagawa studio, with volcanic soil brought from Fuji so that the ground would match. The interiors were shot in a smaller Tokyo studio. The forest scenes were a combination of actual Fuji forest and studio shots in Tokyo. Washizu's mansion was shot in the Izu peninsula.

In Kurosawa's own words, "It was a very hard film to make. We decided that the main castle set had to be built on the slope of Mount Fuji, not because I wanted to show this mountain but because it has precisely the stunted landscape that I wanted. And it is usually foggy. I had decided that I wanted lots of fog for this film... Making the set was very difficult because we didn't have enough people and the location was so far from Tokyo. Fortunately, there was a U.S. Marine Corps base nearby and they helped a great deal; also a whole MP battalion helped us out. We all worked very hard indeed, clearing the ground, building the set. Our labor on this steep fog-bound slope, I remember, absolutely exhausted us; we almost got sick."

Washizu's famous death scene, in which his own archers turn upon him and fill his body with arrows, was in fact performed with real arrows, a choice made to help Mifune produce realistic facial expressions of fear. The arrows seen to impact the wooden walls were not superimposed or faked by special effects, but instead shot by choreographed archers. During filming, Mifune waved his arms, ostensibly because his character was trying to brush away the arrows embedded in the planks; this indicated to the archers the direction in which Mifune wanted to move.
