A 40 disc collection released in 2011-2012 by Office YK. All(?) of these were previously unavailable on DVD. The discs are Region 2 and have no English subtitles or dubs as usual. Based on the one disc I have seen, quality is alright… it was in OAR and anamorphic.
The Japanese Amazon has marked these discs as adult products so they won’t be shipping them outside Japan (unless it is a fulfilled by Amazon item that the seller has agreed to ship internationally) so only way to buy from there would be to find third party (marketplace) sellers willing to ship internationally. As long as the lists work at Amazon, you can find all 40 discs here (in two parts, and cover images can be seen only after clicking one and confirming you want to view them):
Part 1 @ Amazon.co.jp & Part 2 @ Amazon.co.jp
On the other hand YesAsia does also stock these titles and will ship them internationally. I couldn’t find an easy way to list them all so this link to YesAsia should take you to a search page with (currently) all 40 discs listed in order of release and some extra non-roman porno discs at the end. Just compare the individual item Publisher Product Codes (these discs have codes NYK-201 to NYK-240) at the item pages to make sure you have the right one (as for some reason YesAsia doesn’t even have images for 30 of the discs). I am not responsible for incorrect purchases.
