The Japanese DVD features outtakes from the film. One of these shows that in one scene where a cooking pot is thrown at a girl, the pot actually did hit the actress and hurt her (although not badly). The shot where this happened does appear in the movie, but any sign of her having been hurt was edited out.

In the bungalow, two female students, Hirono and Mitsuko, are having a beef. Hirono taunts Mitsukso, who loses patience and cries out, 'I've had it! Why does everyone gang up on me, what did I do!'
