During the ferris wheel sex scene, the woman's arms change position between different shots: in every other angle, her arms are bouncing at her side, but in when she faces the screen her arms are flailing in front of her.

During the strip tease scene, the blonde stripper is shown posing in front of Takeaki's mirror wearing a bra and shorts. In the next shot, we see a reflection of the stripper topless, but in the shot after that, we see the stripper facing the screen with her bra still on.
