Visible crew/equipment: After defeating Gunbei in a duel, Itto enters a temple to pray to Buddha. As Itto walks to the altar the camera passes by a number of pillars and statues and the shadow of the camera is cast on them a couple of times. (00:34:24)

1 visible crew/equipment mistake - chronological order
Directed by: Buichi Saito
Starring: Akihiro Tomikawa, Michi Azuma, Yoichi Hayashi
Revealing mistake: At the beginning of the film O-Yuki is fighting the men in the forest and kills them one by one. When she kills the last one there is a close-up shot of her dagger entering his rib area and blood sprays out. However, if you pay close attention you can see the blood sprays out of his sleeve (presumably there is a device in there), not his torso. (00:01:18)
