This is a 3-CD set. Disc 1: Music CD Disc 2: Program CD with movies and games Disc 3: Card printing, lyric cards, and flashcards I purchased this when I was attending Shichida Child Academy. You can efficiently learn the locations of prefectures, prefectural capitals, and local specialties through songs. You can also create flashcards and play the music while showing them to your child. I have used it a few times. I have confirmed that it works, but please understand that this is a used item. It will be shipped in simple packaging. Please refrain from price negotiations! ・If you have any questions, please be sure to inquire in the comments before purchasing.
