I think it is awesome. In these ever-increasingly incorporeal days, extra special graphic design and packaging is something to be savored. I love how this is another sweet example of the Japanese artfully exploring the possibilities of paper.
Far to often, graphic artist's contributions to music releases are sadly unheralded. I grew up admiring album art designed by Hipgnosis, but at the time never realized that a seperate group, apart from the musicians, was actually responsible for the look and feel of many of my favorite records.
Nice Hipgnosis site.
