As stated in the SPfreaks notes for the JP Oceania release ( http://spfreaks.com/?page=IMGVIEW&item=13525 ), the website http://emij.jp/sp/e/ takes you to a questionnaire regarding the purchasing of the Oceania CD. Below, you can find the translated web pages. You need a unique code to register for the prize?, so hurry up and buy a JP copy!
yeah, i don’t know. these pics came out rather crappy, i tried to improve them, but it just gets pixelated. sorry about that. i honestly don’t know exactly what is supposed to happen, but if you register, you could be one of 10 people a month to receive 5,000 Yen (roughly $60). that’s what i’m gathering out of this.
