Daigasso! Band Brothers DX's menus are in Kanji, but the song titles (It's a rhythm game) are in furigana, as is the karaoke. In my sig you can download a song pack for the game, and though the songs in the top packs have been romanized, the songs in some of the Other Packs folders are in furigana. Either way, even the romanized songs have furigana karaoke lyrics. There's also an english version of the game, titled Jam With the Band, if you want the English menus.
