Most bewilderingly, nothing in the news reports or blog entries I’ve looked at thus far give any indication as to why, out of the tens (hundreds?) of thousands of adult doujinshi and manga published in Japan, Miyashita’s works were specifically targetted.  Consignment sales of doujinshi through bookstores is nothing out of the ordinary, and with so little concrete information, some bloggers have sinisterly posited that the investigation may have originally been spurred by tax evasion suspicions, along with far more obvious theories such as the ongoing media backlash against “lolicon” or lack of proper mosaics.
