From Shima Ceramics:

"Jorogumo, the Orb Weaver Spider Demon, is one of my favorite Japanese Yokai (spirits/demons)! Although she’s now known as 'entangled bride', back in the Edo period her name translated to 'spider lady'. The story is that, when an orb weaver spider lives 400 years, it grows gigantic and gains magical abilities. Jorogumo can present as either a spider with the head of a woman, or just as a beautiful woman, with the intent to seduce and exsanguinate unsuspecting men. "

There were 4 main color-ways of this design (red, black, black & gold, green). Later one-offs including all gold were made also. The run will total 50 of this design, but spread out amongst several color-ways.
