nakat hideo's pinku eiga

[robin]

Hello to all and Merry Christmas! 

I am looking for information about Hideo Nakata's achievements 
in the pinku eiga or roman porno genre.
I heard about a film called something like "Uratosatsu Nanpado" 
with Okamoto Hidetoshi (Zero Woman) and Kaoru Higuchi 
Does anyone know about this film (featured on a Nakata official web site, but with few details concerning the storyline)?
Does anyone know about other erotic films by Nakata? 
(Sorry, I don't have any Thomas Weisser book!)

Thanks to all in advance,

Robin
