help for film searching

[=%ISO-8859-1?Q?Luca_C._Sanso=E8?=]

I introduce my self:

My name is Luca Sansoé, I'm the president of the Cultural Association
NEONEIGA based in in Turin, Italy. Our mission
is the diffusion of Japanese cinema in Italy, through our website
www.neoneiga.it, retrospectives and books. We have worked with
different partners: the National Cinema Museum of Turin,
JapanFoundation, Far East Film Festival and others. In 2006 and 2007 we
organized with the National Cinema Museum probably the biggest  Miike
Takashi's retrospective ever made till now, with 26 movies, and a
Kurosawa Kiyoshi's retrospective, both in presence of the directors.
This years we are working with the Turin Int'l GBLT Festival scheduled 
from
April 17th to 25th. We are going to present a selection of films 
(around 15)
from the 60s to now, to trace a path trough the representation of
homosexuality in japanese cinema.
We are still looking for some titles which seem as interesting as hard 
to find:

Konuma Mararu's LESBIAN NO SEKAI: KOUKOTSU (LESBIAN WORLD: ECSTASY, 
1975).
We do not have much infos about this movie nor can we find a copy in 
DVD or VHS, even without subtitles.

The Kojima Yasushi's documentary RASEN NO SOBYO (Rough Sketch of a 
Spiral, 1991).
Probably the first documentary about homosexuality in Japan, but it 
seems impossible to find, even without subtitles.

Zeze Takahisa's SANCTUARY (aka Mrs., 2006)
We love Zeze's movies and we think that this one might be a better 
choice then other 2006 titles, like Maison de Himiko or Boys love, 
which didn't seduce us...

We would be very grateful to anyone who could help us finding these 
films. Any general suggestion or advise is also more than welcome.

My best regards,

Luca C. Sansoé
