I mentioned already but Shoujo Tsubaki isn't truly banned, in the whole sense of the word.
Look, the film got made in the span of 5 years and released in 1992
After his initial screening in a red tent made for the movie, Harada submitted it to the Eirin Board and they requested 29 edits so the film when from 53 to 49 minutes.
It was screened privately from time to time up until 1999 when the original film print was shown outside of Japan, like for real.
When it arrived back at Japan, Japanese Customs from the airlines seized and destroyed the film print.
Harada had save only a Betamax of the film since and he learned that the negatives were destroyed by what it seemed more of a dick move, he got pissed off and refuse to let the movie being shown again afterwards.
But in 2006 he mellowed enough to allow an official DVD release on France and even made a documentary for it, it's even on YouTube (hard to watch due to being spliced with scenes from the Alpha Gory bits but what he says comes from his own mouth and it's rich).
Since, the film was shown on festival screenings at least twice in Japan as of 2013 I recall.
