Right when I saw this post I took out my Pokémon Bible. Glad I bought it a couple of months ago. *Now where did I put those magnifying glasses…*
I also can’t seem to find anything resembling it in the book nor on Bulbapedia. It looks so familiar though. Too bad it’s so small, but it’s most likely a trainer card (and somehow it reminds me of the style of illustrator Nobuyuki Habu… ).
Now I want to know which card it is…
I can’t help you with any translations, though. I can’t read symbol Japanese, and only know a word or two in Japanese written with the regular alphabet.
