Despite living in the land of Habu and Noro, I hardly ever buy Japanese yarn - the shops near my apartment stock mainly overpriced, acrylic fare - but I thought these were too pretty:
Span Jewel (about ¥715 for a 68 meter ball) is a nylon, acrylic, wool and polyester blend, with sequins (sequins!) and a fuzzy halo around a metallic base.
I also picked up one ball of Bacara Pur Fine (a nylon mohair wool blend?) to match - I'm really not too sure what I'm going to make with them. Something awesome, hopefully, which probably means that I'll reject about a million ideas on the grounds of not being awesome enough, which is what always happens when a ball of awesome yarn finds its way into my hands...
