Searched, didn't find anything so apologies if old.
Not sure if many here have Japanese PSN+ but if you do, a bunch of titles are currently free. List of titles: http://www.jp.playstation.com/psn/plus/123titlelineup.html
Not familiar with a lot of these, but some I know. Kings Field 1-3, Shin Megami Tensei If.., 峠MAX 2, blah blah.
If you have a JP PSN account, I believe this link (JPSN store) is a free 15 day trial for Plus.
Edit: As req.,video on how to set up JPSN account.
