Doubtless Mouse:
The law I mention appeared in 1907. From
http://www.hawaii.edu/aplpj/pdfs/v4-06-Alexander.pdf :
" ...Article 175 of the revised 1907 Criminal Code, which specified that:
A person who distributes or sells an obscene writing, picture, or other object or who publicly displays the same, shall be punished with imprisonment... or a fine.
The same applies to a person who possesses the same for the purpose of sale. Under enforcement of Article 175 of the Criminal Code, obscenity displayed in any form could not be sold, loaned, or passed to the public in any ashion for any reason. Furthermore, obscene material could not be shown to any member of the public, hether alone or in a group."
I agree that art in older Japanese, as well as other Asian, cultures often portrayed an exagerated phalus. Note that the law does not actually define what "obscene" means, an issue that we deal with today in US law. The reference cited above indicates it was customary for government censors to define any exposure of the genitals as being obscene, and therefore prohibited. However, exclusions could be made where redeeming artistic value existed. It is also indicates that Japan sought to align their definition of obscenity with that of the western world, as trade was becomming more important. Given a few years lag, this may have meant the adoption of Victorian concepts of obscenity at the time of drafting the law. In the west in the Victorian years, if you were wealthy, your prurient pictures were called Art, not pornography, and perhaps the same double standard existed in Japan.
