Hideki Matsui identification help

I picked up this card as part of a large lot of assorted Japanese baseball cards from a fellow in the Philippines, but can't find it listed in the last two editions Gary Engel's Japanese Baseball Card Checklist and Price Guide.



Any ideas?  The front shows Matsui's first NPB home run, but judging from the back, it's probably from late 1996 or 1997.  Stadium give-away perhaps?

Fame is fleeting....

...but Ee-Yah!! is forever.
