The first two cards were issued in SCM #53 which was published in September of 2005. The cards are of Masatochi Kakuno of the Tokushima Indigo Socks and Masaki Hiyashi of the Ehime Mandarin Pirates:
It's possible that these two cards are promos for a BBM Shikoku Island league set but I've never seen or heard of one. One the other hand, I had never seen or heard of BBM's cards for the GPBL until Ryan found them last year so maybe there is one.
The other card is from 2009 and features Hideki Irabu. Irabu has last played professionally with the Hanshin Tigers in 2004. He appeared in 10 games in 2009 with the Long Beach Armada of the Golden Baseball League before returning to Japan and signing with the Kochi Fighting Dogs and appearing in two games late in the season (I'm not sure when exactly he was with Kochi - Baseball Reference says his last appearance with Long Beach was August 5 and I think Japanese Wikipedia says he pitched with Kochi in September). This was his final professional appearance. The card was issued in SCM #77 which I believe was published in late September of 2009 (which is why I'm not convinced that he only pitched for Kochi in September). The card is in the style of the 2009 BBM 2nd Version set (well, the 1st Version Update subset so it's really the style of the 1st Version set) and has a number of 810 which makes it what I call a "bonus" card for the 2009 BBM sets:
