The first issue Japanese cassette release of Lionheart features the same album artwork as the UK release, but with the addition of some bold text, photos and background colour. As you may have noticed already, which I've probably neglected to mention on other posts, these cassette inserts are pretty unique with their double spines.
The inner portion of the insert is pretty boring by comparison, and most of them are pretty much like this - a basic listing of the tracks on one side and a listing for different releases printed on the other side.
The cassette shell for Lionheart has JAPAN stamped directly into it on the first side only. The early cassette shells and sticker labels are pretty much identical on all early album releases. I really can't say if this changes at all on the later releases as I pretty much stopped collecting them after Hounds of Love. By that point the inserts were looking more and more like any other common release you could find in any country - and the appeal for them was lost on me.
This release also comes with a double-sided English lyric sheet. It's a really long strip of folded paper, which I had to scan and chop into sections, otherwise you wouldn't be able to read any of it. As I've pointed out in other releases, the paper is very thin, similar to newsprint paper.
