Continuity: Spoiler: When Okaa-san says she wants to adopt Sayuri, which provokes Hatsumomo's anger, Okaa-san's cigarette keeps changing its own size, being at times totally consumed, and sometimes not.
Anachronisms: Sayuri is the Year of the Monkey, not the Rooster.
Crew or equipment visible: During the fight between Sayuri and Hatsumomo in Sayuri's room a crew member walks through the left side of the shot.
Continuity: When Mameha cuts Sayuri's leg, during the dialogue Sayuri has a red ribbon and a pink comb in her hair. The pink comb disappears and reappears throughout the shots.
Revealing mistakes: When Chiyo/Sayuri and Pumpkin are listening on Mrs. Nitta and Mameha's discussion of Chiyo's future, and the camera zooms in on the girls' eyes peering through the crack in the door, Chiyo's eyes move very fast and you can clearly see Chiyo's blue contact, since it does not move with the rest of her eye.
Continuity: When Chiyo apologizes to Mameha about the kimono; when she first bows both sleeves of her kimono are behind her arms but in the next scene when Mameha kneels beside her, the right sleeve is on top of her arm instead of behind it.
