This is the Japan version of the 10th Anniversary Bonus Pack. You'll easily recognize it, because it looks nearly identical to the one released in the USA. (note small Japanese writing at the bottom under the logo) It contains the exact same items the USA got: music disk, booklet of info, golden color coin, fold out interior case thing. It DOES NOT contain a copy of SA2 Battle as some things imply. This is only the bonus goods. You may be able to buy it at GameChoiceClub.com in 2011, if any remain. It will cost about 50.00 though, as it is old. (Initially, it was free with purchase, for 2 days only--they have apparently obtained old unused stock) 

The blue case for the set (That's inside that colorful cover seen above) is made out of foamcore & uses shiny gold ink for the Anniversary logo. The interior of the case has areas for the coin, book & CD

The all white book cover is very classy with it's embossed Anniversary logo. The interior of the book has the same info as the English version, & is written in both Japanese and English. The main difference between versions seems to be the outer sleeve thing.
