Question: PERFECT EDUCATION 3

I wonder if the third Perfect Education is a co-production between Japan and Hong Kong. The movie isn't on the hkmdb. The director (Leung Tak Sam) and many of the actors involved (as Tony Ho and Lam Suet) are hongkies. The film is spoken both in japanese and cantonese. The three production companies are Same Way, Matsushita and Art Port. Could be one of these Sam Leung's own company?
I found some info on the Same Way's official website:

In this essay for the Udine's Far East Film Festival Catalogue Tim Young wrote: «Director Sam Leong meanwhile directed an elegant blend of erotica and art house stylings in the Hong Kong-Japan co-production Perfect Education 3, although the movie went straight to video.» Here's the complete essay: http://194.21.179.166/cecudine/datahost/fef2004/english/hongkong2004.htm.
What do you think? If you want I can post all the dvd screenshots.
